At TWG Global, your contributions will support our goal of sustained growth and superior returns, as we deliver rare value and impact across our businesses. 

The Role:

As a Principal Machine Learning Engineer (UK), you will be embedded in the UK Data Science team and play a critical role in accelerating delivery of AI solutions. Reporting to the Head of the UK AI & Data Science team, you will work alongside Data Scientists to take prototypes and translate them into reliable, production-ready services for business stakeholders.

This is a hands-on technical leadership role: you will set direction, architect solutions, and mentor peers. The remit is squarely focused on last-mile delivery — taking prototypes built by Data Scientists and making them usable in real business settings by packaging them into services or APIs, wiring them into data sources, building lightweight feature and inference pipelines, and adding basic monitoring and retraining logic. You will accelerate pilot deployments so stakeholders can see value quickly, and then hand the solution off to the Central Engineering and Data team, who are responsible for firm-wide platforms, scaling, and long-term support.

The ideal candidate will also bring applied data science skills and be comfortable moving between ML engineering and data science work. You should be able to contribute to model development and analysis when needed, in addition to owning deployment and operationalization.

Responsibilities:

• Translate data science prototypes into production-ready pilot ML services tailored to business use cases.
• Build lightweight pipelines (feature engineering, model packaging, inference services) that integrate smoothly with central platforms while meeting immediate delivery needs.
• Champion pragmatic MLOps practices (CI/CD for ML, monitoring, observability) to improve reliability without duplicating central engineering’s enterprise frameworks.
• Partner closely with Data Scientists to operationalize models, and collaborate with central engineering to plan handoffs of successful pilots for hardening and scale.
• Apply emerging ML engineering techniques (LLM deployment, RAG, vector databases) to accelerate delivery of applied projects.
• Develop reusable components and lessons learned that central teams can adopt into firm-wide platforms.
• Ensure ML workflows comply with governance, audit, and regulatory requirements.
• Collaborate with central Engineering, Data, Product, and Security teams to ensure alignment with firm-wide platforms and standards.
• Provide technical mentorship to ML engineers, raising the bar for applied delivery and model deployment.
• Flex into data science tasks when needed: feature engineering, model experimentation, and analytical insights, reflecting the versatility required in a fast-moving team.

Requirements

• 8+ years of experience designing, building, and deploying ML systems in production.
• Proven track record of leading ML engineering projects from prototype to production delivery.
• Deep expertise in modern ML frameworks (TensorFlow, PyTorch, JAX, Ray, MLflow, Kubeflow).
• Proficiency in Python and at least one backend language (e.g., Java, Scala, Go, C++).
• Strong knowledge of cloud ML infrastructure (AWS SageMaker, GCP Vertex AI, Azure ML) and containerized deployments (Kubernetes, Docker).
• Hands-on experience with ML pipelines, distributed training, and inference scaling.
• Familiarity with monitoring stacks (Prometheus, Grafana, ELK, Datadog).
• Experience in regulated industries (finance, insurance, healthcare) with compliance and governance needs.
• Strong communication and collaboration skills, with the ability to mentor others and influence technical direction.
• Working knowledge of data science techniques (e.g., supervised/unsupervised ML, model evaluation, causal inference, feature engineering).
• Bachelor’s or Master’s degree in Computer Science, Machine Learning, Data Science, or a related technical field (PhD a plus).

Preferred Experience:

• Experience integrating with Palantir platforms (Foundry, AIP, Ontology) as a user/consumer.
• Practical exposure to LLM and GenAI delivery (fine-tuning, RAG, vector search, inference).
• Experience optimizing GPU clusters or distributed training workloads.
• Familiarity with graph databases (Neo4j, TigerGraph) in applied ML contexts.

Benefits

• Work at the forefront of AI/ML innovation in life insurance, annuities, and financial services.  
• Drive AI transformation for some of the most sophisticated financial entities.  
• Competitive compensation, benefits, future equity options, and leadership opportunities.

We are looking for someone who is as excited about Unitary’s mission as we are, who wants to have a large impact at an early-stage startup, and be a key part of defining Unitary’s future as one of our early employees. We need versatile people who are happy to get stuck into whatever needs doing, and are ready to learn and grow with the company.

For this particular role, we need a proactive software engineering expert who is familiar with using AI tooling and prompt engineering, and who is comfortable engaging with customers and exploring and presenting new ideas. Strong communication skills are essential, as you'll lead technical deliveries and bring others along on the journey. You embrace a product mindset in everything you do and should demonstrate a genuine curiosity for solving current and future customer challenges.

We would love to hear from you if you:

• Have strong Python and engineering skills, with experience using and applying AI to solve customer problems
• Can (or want to learn to) develop agentic AI systems that can automate human processes
• Have an understanding of (or want to learn) how software is deployed through Kubernetes, and with the capability to deploy some infrastructure elements independently
• Can demonstrate problem solving and project management skills in order to analyse workflows and design automated solutions
• Thrive in a collaborative environment where group output and team achievements weigh heavier than individual input
• Can travel to our company-wide offsites three times per year

It would be even better, but not essential, if you have:

• Experience working in a fully remote, international team
• Previous startup experience
• A background in building and operating agentic AI systems
