Job description

Own the architecture, ship the code and help shape a growing engineering team.

A growing technology business is hiring a Senior Backend Engineer to take ownership of substantial backend projects and help introduce new AI capabilities into its product.

You’ll join a small, experienced team where engineers make decisions and carry their work from initial idea through to production. With a busy integration roadmap and plans to expand engineering, you’ll have meaningful influence over both the platform and how the team builds it.

The opportunity

• Own backend services and complex partner integrations from design through deployment and production support.
• Make architectural decisions across data integrity, security, scalability and performance.
• Build practical AI features using existing models, APIs and agent frameworks.
• Work directly with product and engineering to scope ideas and ship useful improvements quickly.
• Help shape engineering practices, with potential to grow into technical leadership as the team expands.

Your experience

• Strong hands-on backend development using TypeScript and Node.js.
• Examples of substantial services or integrations you’ve personally designed, built and operated.
• Experience with SQL, relational data modelling, APIs and cloud production systems.
• Sound architectural judgement and confidence making progress with incomplete requirements.
• Practical AI or agent implementation experience, commercially or through personal projects, would be particularly relevant.

You may currently be a Senior Backend Engineer, a backend-focused Full Stack Engineer or a Technical Lead who wants to remain close to the code. Experience in a small product team, startup or independently building and launching products would be valuable.

Package & location

• Competitive base salary plus a substantial share-option package.
• Flexible hybrid working, with a Dublin City Centre office. Typically one day on site per week.
• Hands-on individual contributor role with broad technical ownership.
• Opportunity to join ahead of planned team expansion and develop towards technical leadership.
