Senior Backend Engineer | Node.js, TypeScript & AWS

Location: Bristol, London, Birmingham, Manchester, Edinburgh - Two days/week in the office starting next year.

Package: Circa £90,000 total package incl cash benefit & pension.

The Opportunity

We're working with an established, product-led technology business looking for a Senior Backend Developer to join its engineering team.

This is an opportunity for an experienced backend engineer to take ownership of key product features, contribute to technical decisions and help build and maintain scalable, reliable software. You'll work closely with engineering colleagues, product stakeholders and designers to turn requirements into high-quality solutions that deliver genuine value to users.

The successful candidate will bring strong hands-on experience with Node.js, TypeScript and AWS, alongside a passion for clean code, sound engineering practices and continuous improvement.

The Role

As a Senior Backend Engineer, you'll play an important role throughout the software development lifecycle, from initial design and planning through to implementation, testing, deployment and ongoing optimisation.

Your responsibilities will include:

• Designing, developing and maintaining robust backend services and APIs.

• Taking ownership of features from initial concept through to production release and ongoing support.

• Writing clean, maintainable and well-tested code in line with established engineering standards.

• Contributing to technical discussions, solution design and architectural decisions.

• Improving automated testing, deployment pipelines and development processes.

• Monitoring, maintaining and optimising existing services to ensure reliability and performance.

• Collaborating with product managers, designers and technical leads to plan and deliver roadmap objectives.

• Supporting and mentoring other engineers, sharing knowledge and encouraging best practice.

• Participating in code reviews and helping maintain consistent standards across the engineering team.

• Working within an Agile environment, adapting to changing priorities while keeping delivery quality high.

Technical Skills & Experience

We're looking for someone with strong backend engineering experience and a solid understanding of modern software development principles.

Essential experience:

• Strong commercial experience with Node.js, TypeScript and AWS.
  

• Experience building backend services and RESTful APIs.

• Familiarity with NestJS or a comparable Node.js framework.

• Experience developing and deploying applications using AWS.

• Understanding of software architecture, design patterns and maintainable coding practices.

• Experience with automated testing, ideally using Jest.

• Proficiency with Git, pull requests and collaborative code review workflows.

• Experience working with relational databases and SQL.

• A commitment to code quality, testing and continuous improvement.

Technologies that would be beneficial:

• AWS ECS and Lambda.

• AWS CDK and infrastructure as code.

• AWS SNS and SQS for messaging and event-driven systems.

• DynamoDB and AWS X-Ray.

• PostgreSQL, T-SQL or Presto.

What We're Looking For

Beyond technical ability, you'll be someone who can work independently, take responsibility for outcomes and collaborate effectively with a wider engineering team.

You should be comfortable explaining technical concepts to different audiences, contributing ideas to improve the product and helping less experienced colleagues develop their skills.

You'll thrive in an environment where priorities can evolve, teams work collaboratively and engineers are encouraged to challenge existing approaches and find better ways of working.

Why Consider This Opportunity?

This role offers the chance to contribute to a live software product, influence technical direction and take ownership of meaningful engineering work. You'll be part of a collaborative team where engineering quality, knowledge sharing and continuous product improvement are valued.

If you're a Senior Backend Developer with strong Node.js, TypeScript and AWS experience and enjoy building reliable, scalable software, we'd be keen to hear from you.
