Fullstack Engineer- SDE IV

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.
