What role will you play? 

As a Full Stack Engineer, you will play a pivotal role in our development team, bridging the gap between the visual elements and the server-side infrastructure. You will be instrumental in developing full-fledged, scalable applications by combining the art of design with the science of programming. With your expertise in both front-end and back-end technologies, you will ensure the entire stack is designed and built for speed and functionality.  

Your day to day will involve designing and developing dynamic, high-quality web applications, leveraging the Node.js and python for the back end services and React/Angular for the front end. Close collaboration with UI/UX designers will be essential, allowing you to bring web designs to life while ensuring high performance and responsiveness. Additionally, you will actively participate in coding, debugging, and testing to deliver reliable solutions whilst also working closely with other developers, designers, and product managers, fostering a collaborative environment to meet project goals and deadlines effectively. 

What you offer 

• Proficiency in Typescript and a good understanding of React  
• Solid experience with the Node.js, including the ability to develop RESTful APIs 
• Experience with containerisation of service using Docker 
• Knowledge of modern authorisation mechanisms, such as JSON Web Token (JWT)  
• Familiarity with SQL databases, such as PostgreSQL 
• Experience with Kafka or other event driven tools and tech 
• Nice to have some experience integrating with LLMs through open AI, Gemini etc. 
• Nice to have exposure to AI tooling – Claude, Copilot, Cursor etc. 
• AWS experience is a nice to have 

Job Responsibilities:

• Design an API, not only implement one.
• Reason about indexes, query plans, transactions, migrations on live tables.
• Handle vendor and third-party integrations, done well: authentication, retries, idempotency, webhooks, rate limits, sandbox-to-production rollout, and reconciliation when the other side fails mid-flow.
• Work directly with a vendor's technical team to get an integration over the line.
• Manage Queues, background jobs and scheduled work, including what happens when a job runs twice.
• Perform React with TypeScript.
• Execute Component design, state management, forms that hold up under real user behaviour.
• Build a clean screen without a pixel-perfect design handed to you using enough CSS and layout sense.
• Ensure Performance and correctness on the browser side: loading states, error states, the ugly edge cases.
• Write Tests you actually write.
• Maintain Git discipline, CI/CD, and enough DevOps grounding to be self-sufficient: containers, environment configuration, pipelines, deployments and rollbacks.
• Understand AWS fundamentals: how your service runs, scales and fails.
• Instrument what you build logs, metrics, alerts so problems surface on a dashboard rather than in a customer complaint.
• Read monitoring output and act on it: triaging an alert, finding the root cause, and closing the loop with a fix or a tuned threshold rather than muting it.
• Keep an eye on infrastructure cost.
• Know roughly what your service costs to run, spotting the query, log stream or API call pattern that is quietly expensive, and factoring that into design decisions.
• Understand the problem first-hand.
• Spend time with the product owner or the ops team that has the problem, and see how the work happens today rather than working from a requirements document alone.
• Design, build and ship end to end.
• Take it to production and keep it healthy.
• Deploy it, monitor it, and act on what the monitoring tells you.
• Watch for Errors, latency, failed jobs and data quality and ideally spot the issue before someone reports it.
• Be mindful of what it costs to run.
• Think about instance sizing, storage, query patterns, log volume and the cost of third-party API calls before you ship, and raise it early when something is likely to get expensive.
• Integrate cleanly with vendors and partners.
• Work well with vendor teams, reading their documentation carefully and handling their failure modes gracefully.
• Be accountable for what you commit to.
• Give estimates you believe in, flag slippage early, and keep the status visible.
• Leave it documented.
• Build securely by default.
