About Seapoint
Seapoint is building the financial home for European startups and scale-ups. We're an AI-powered business account that handles everything from payroll and expenses to invoice payments and reporting - all in one place.

Founded by Sean Mullaney (former European CIO at Stripe) and a team of alumni from Stripe, Wise, Wayflyer, Nubank and Tide, we've just raised $3M in pre-seed funding led by Frontline Ventures. After 9 months of building, we're now in private beta with dozens of VC-backed startups who are finally getting the bird's-eye view of their finances they've always needed.

The problem we're solving is real: European startups are stuck between neobanks (too small) and traditional corporate banking (too big). They're juggling 4-6 different financial products, running processes manually, and earning no interest on cash deposits. We're changing that with AI automation that handles the tedious financial work, so founders can focus on building their businesses instead of managing spreadsheets.

Read more about what we’re building here .

About the role
Build intelligence into the financial stack.

You'll develop AI-powered features that automate transaction categorization, generate instant management accounts, and predict cash flow needs. Working at the intersection of machine learning and financial services, you'll ship systems that save founders hours every week.

We value engineers who approach problems with genuine curiosity and are willing to experiment with quickly evolving AI tools and development practices. You'll work alongside ex-founders and veterans from Stripe, Wise, and Tide who understand what startups need to scale.

Note: Open to candidates authorised to work in Ireland/UK. Exceptional remote candidates across Europe considered.

Requirements

Essential Qualifications:

  • Experience in ML engineering - a minimum of 3 years relevant experience
  • Fluency in Typescript or one major programming language like Java, Ruby, Go, Python, etc
  • Experience training ML models and/or optimising RAG with LLMs
  • Strong product instincts—showcase prior experience in designing and developing key customer features supported by AI
  • A passion for utilising AI to address genuine financial challenges.

Interested in learning more about our project? We would love to discuss it with you.

Benefits

  • Competitive salary with meaningful equity in a fast-growing fintech startup
  • Work directly with experienced founders and engineers from Stripe, Tide, Wise, Nubank, Wayflyer and other fintech unicorns
  • Front-row seat to building category-defining financial infrastructure for Europe's startup ecosystem
  • Flexible hybrid working from our Dublin base
  • Learning and development opportunities in fintech and AI

About 9fin

The world's largest asset class, debt, operates with the worst data.

Technology has revolutionized equity markets with electronic trading, quant algos and instantaneous news. However, in debt capital markets, the picture is completely different. It still behaves like it’s in the 1980s; trillions of dollars of trades are placed over the phone, news is slow, and corporate credit information is imperfect and scattered.

Our mission is to change this.

9fin's proprietary technology delivers fast and comprehensive financial, credit, legal & ESG analysis. Our clients are able to make faster, more informed decisions, win more business and most importantly, save time.

Our fast growing list of clients include 9 of the top 10 Investment Banks, leading Asset Managers, Hedge Funds and Law Firms.

What you'll work on
  • This role is the opportunity to take on the technical leadership on projects, defining and designing systems, making quick proof of concepts and working closely with Product and our Clients.
  • Write code and lead others in the team in delivering new service functionality, implementing API’s, data routing/processing and automation mechanisms.
  • Development and engineering primarily on the backend services and web application hosted tools and systems of the 9fin platform.
  • Taking a leading role within project teams as a senior IC, running code reviews and mentoring of junior developers, involvement in early research and experimentation with new technologies providing input for new features and products.
  • Continually improve on the 9fin codebase taking the chance to automate, refactor and document when you can.
  • Variety: Our web platforms are incredibly diverse, from complex financial data modelling, capturing environmental, emission, energy data, incorporation of ML/AI prediction services, data visualisation serving and automation systems.
  • Collaboration and teamwork: Cross functional teams are formed for all projects including the appropriate domain expertise from 9fin financial, legal and editorial colleagues. This allows the best quality information and feedback to go directly to engineering project teams. Your ability to explain and break down complex projects to non technical audiences will enable productive and efficient team progress.
  • Developer Experience: Through managed automated preview environments, feature flags and well maintained non production environments. You will be able to move with velocity and get feedback and iterate quickly.

Our Backend Stack

  • Python is the dominant backend language used
  • Flask & FastAPI
  • Typing is used within our Python stack to power automated documentation and API definitions
  • Relational Databases (PostgreSQL) at the heart of majority of services
  • We’re AWS for Cloud hosted services
  • Heavy use of AWS lambda Serverless
  • Docker (AWS ECS) for uniform development/deployment from dev to prod

Requirements

This role will be a great fit if you:

  • Can effectively plan and reason about your software, understanding where it fits into systems and the overall business
  • Can think about how data will pass through your software; from persistent storage through to API endpoint
  • Experience with Python and its web frameworks (we currently use Flask, and are moving to FastAPI with Typing)
  • Strong experience delivering APIs, Service Oriented Architecture
  • Good working knowledge of SQL statements for retrieving data
  • A good collaborator and communicator with cross functional engineering teammates and others within 9fin
  • Code Quality: Through writing testable, maintainable code, and by engaging in code review for your own work and for reviewing others

Benefits

We’re a scaling start up and we enjoy sharing our success, when the company succeeds, we always reinvest that in our people. We also offer huge amounts of responsibility, an abundance of opportunity for growth and a platform to truly excel.

Financial & Insurance

  • Competitive Salary(our salary bands are benchmarked at the top end of the market)
  • Equity options
  • Pension (your minimum contributions are 4% with 9fin matching up to 7%)
  • Private Medical Insurance
  • Paid sick leave with Income Protection for long periods of illness
  • Group Life Assurance
  • Season Ticket Loan & Cycle to Work schemes

Time off

  • 25 holiday days per year
  • Local public holidays (with the ability to exchange them for alternative days)
  • Hybrid working model, to allow you the flexibility to decide how, where and when you do your best work
  • Work abroad for up to 3 months a year
  • 1 month paid sabbatical after 5 years of service
  • Enhanced parental leave & flexible working arrangements available

Training & Culture

  • Professional learning and development budget
  • Quarterly team socials
  • Summer and Winter company social events
9fin is an equal opportunities employer

Don’t meet every single requirement? At 9fin we are dedicated to building and promoting a fair and inclusive workplace where everyone can flourish, reach their full potential and truly belong. We recognise diverse teams allow a more creative and productive environment. So, if you’re excited about this role but your experience doesn’t perfectly align with the job description, we encourage you to apply anyway.

London
Business Area
Engineering and CTO
Ref #

**Description & Requirements**
Are you passionate about building high-performance systems that are fast, resilient, and operate at global scale? Join Bloomberg's Application Middleware SRE team, where you'll combine software engineering and systems expertise to keep the backbone of the Bloomberg Terminal running smoothly for hundreds of thousands of users around the world.
We're not your typical SRE team. We're embedded in a group that powers real-time connectivity, and we own systems where uptime isn't just important-it's essential to the global financial system. This is your opportunity to engineer resilience at scale, automate critical infrastructure, and shape reliability practices across one of the world's most powerful tech platforms.
**The Team**
We're the Site Reliability Engineering team within Bloomberg's Application Middleware group. Our mission: ensure that Bloomberg's core connectivity and messaging layers are resilient, scalable, and fully observable.
We own systems that operate at high throughput and low latency, including:
+ Gateways: Secure, high-performance TCP/SSL entry points to our data centers
+ HFN & NSTP: A global HTTP CDN and SOCKS5 proxy network delivering fast access from any geography
+ Playlist Services: Dynamic path configuration systems optimizing user connectivity in real-time
+ PGM Relays: Infrastructure for reliable multicast data delivery
We use automation, observability, and software engineering to detect issues before they impact customers and reduce manual toil wherever we can.
**What You'll Do**
+ Build production-grade software that powers Bloomberg's global infrastructure
+ Design and implement scalable, fault-tolerant systems with a focus on observability, performance, and automation
+ Collaborate across engineering teams to introduce automated, self-service operational workflows
+ Conduct deep systems analysis and root cause investigations for complex, distributed systems
+ Propose and prototype innovative approaches to reliability and risk mitigation
+ Contribute to design docs, runbooks, and post-incident reviews-clear communication is part of the job
**You'll Need to Have**
+ A degree in Computer Science, Engineering, Mathematics, or equivalent practical experience
+ Strong software engineering skills in any high-level language (we mainly use Python and C++)
+ A deep understanding of software system reliability and risk management-including how to identify potential points of failure and design mitigation strategies.
+ A good understanding of data structures, algorithms, and system design
+ Experience navigating and improving large, distributed codebases
+ An ability to identify system risks and engineer around points of failure
+ Clear written and verbal communication, including technical documentation and incident analysis
**We'd Love to See**
We are building a team with a breadth of expertise and value depth in any of the following areas:
+ Systems Knowledge: A strong grasp of operating systems, fundamental networking protocols (TCP, UDP, multicast), or core database concepts as they apply to modern infrastructure.
+ Cluster Management: Experience with deployments, staging, and configuration management. Direct experience with Argo and/or Kubernetes or other Pipeline Management Platforms is a significant advantage.
+ Machine Management at Scale: Experience with capacity planning and automating the lifecycle of large machine fleets.
+ System Observability and Monitoring: Deep understanding of SLIs/SLOs/SLAs, alerting, and building dashboards for complex systems.
+ Reliability in Distributed Systems: Knowledge of fault tolerance and the unique challenges of network and node failure in distributed environments.
+ Mentoring: Proven experience mentoring and growing junior Engineers
Bloomberg is an equal opportunity employer and we value diversity at our company. We do not discriminate on the basis of age, ancestry, color, gender identity or expression, genetic predisposition or carrier status, marital status, national or ethnic origin, race, religion or belief, sex, sexual orientation, sexual and other reproductive health decisions, parental or caring status, physical or mental disability, pregnancy or parental leave, protected veteran status, status as a victim of domestic violence, or any other classification protected by applicable law.
