We are looking for Principal Frontend Developers (we call them Software Craftspeople) who share the same values of pragmatism, professionalism and transparency that we do. We are not your typical consultancy! We believe in having a great work/life balance so we won’t be asking you to travel all over the place! Any travel would be restricted to your main office branch (London). Any client work that is outside of these locations would be undertaken remotely.

We support our clients in many ways and you will have the opportunity to work on a wide range of different internal and client projects. Perhaps you’ll work on a client project from our offices with our team delivery approach. This may be a greenfield project for a startup, or helping to build a mission-critical system for a large enterprise client. Perhaps you’ll work as an embedded craftsperson, working within our client's existing development to help them to get better at writing their own software. Or maybe you're more interested in helping to introduce the values of Craftsmanship to an organisation through coaching & mentoring.

Location: London. Please note that we are not able to offer visa sponsorship at this time.

What about you?

You consider yourself a Software Craftsperson. For you, writing code is part of your job and also a source of joy. Test-Driven Development is how you like to or would prefer to write code - preferring to work in small increments, trying things out and iterating rapidly, tightening the feedback loop as much as possible, and letting your tests drive the design of the code.

You are a team player. You understand that software lives on long after it is first delivered and that many different people will contribute to it over its lifetime.

As a curious developer, you spend time investing in your craft, learning new technologies and practicing different techniques and approaches.

Requirements

What about you?

As someone performing this role, these are some of the things we are looking for:

• Client Engagement: You are able to actively build relationships with strategic stakeholders within the client, acting as an advisor and partner in helping them identify and solve problems. You are good at helping people come up with a vision and helping them get aligned behind it.
• Broad technical knowledge and skills: You are able to advise on multiple technology stacks at both high and low levels. You can even help a product team with value discovery through prototyping, research, and are able to quickly gain a deeper understanding of the business domain. (We mainly work with the React, Angular, or Vue.js, alongside cloud technologies).
• Project Management: You have a proven track record of executing and planning a technical or product strategy, and identifying and managing risks.
• Communication and Leadership: Versatility in leadership and communication styles is key for a role like this. Facilitation skills are a key part of this job.

It would be an added bonus if you:

• Actively participate in a technical community.

• Have experience of working in a software consultancy, or have been part of implementing some kind of organisational transformation (Agile, Lean, Digital).

• Have a deep understanding of software development best practices, working with legacy code, re-architecture, cloud technologies, software design, etc.

Benefits

• Personal learning budget - access to Learnerbly, our online learning and development tool, to support your personal development and career progression here
• Training - no fixed training budget. So long as the course is relevant for the company and you’ll do a lightning talk on the subject, we’re happy to pay for it
• Life cover and private medical - Long term sickness cover. Private medical cover including dental, hearing and optical
• Long service awards - two additional days of holiday when you enter your third year (on top of 25 days), two additional days after five years, two additional days after eight years (31 days in total) and a month fully paid sabbatical after ten years of service
• Pension (4% top-up) and income protection - Option to choose from an employer pension top-up to 5% or a holiday voucher for the value of £1000 after 5 years of service. 8% pension top-up or a holiday voucher for the value of £2000 after 8 years of service
• Employee assistance program (EAP) including access to well-being support (counselling, therapy)
• Enhanced parental leave
• Electric car and cycle to work scheme

Everyone should have the right to bring their whole self to work and be celebrated for who they are. Our people are hired purely on their commitment to these values and their ambition to deliver outstanding results for our clients. Codurance is proud to be an Equal Opportunities Employer and is committed to fostering an inclusive workplace.
