Senior Full Stack Engineer

Full Stack Development LeaderWe're looking for an experienced Full Stack Development Leader to own features end-to-end: backend services, frontend experiences, and the data flows that power them.Your primary strength is building web applications and APIs, and you have some experience working with databases or analytics, plus a clear interest in doing more with data integration and pipelines.You'll design and build APIs, UIs, and supporting infrastructure, and you'll also build and maintain frontend SDKs (Next.js/React) that other teams can use to integrate with the platform.Product Feature Delivery: Design, build, and ship user-facing features across backend and frontend; own requirements from spec to production rollout.Backend Services: Implement and maintain RESTful (and occasionally event-driven) services; design clean request/response contracts; handle auth (OAuth2/OIDC/JWT), rate limiting, idempotency, validation, and auditing.Frontend Development & SDKs: Build responsive, accessible UIs using React/Next.js + TypeScript (dashboards, admin/ops views, analytics-flavored screens). Design and maintain a frontend SDK (hooks, components, and utilities) that product teams can use to integrate with backend APIs and data services. Provide example Next.js integration patterns and reference implementations.Data-Aware Design: Work with product and data teams to design schemas and models that support both product workflows and analytics; understand how data will be queried and reported on.Integration with Data Pipelines: Collaborate with data engineers to consume and expose curated datasets; design APIs and services that sit on top of warehouses/lakes and operational databases.Infrastructure & DevOps: Use Terraform or similar IaC to provision and manage app infrastructure; automate build/test/deploy with CI/CD; write solid shell scripts for glue/ops tasks.Observability & Reliability: Instrument structured logs, metrics, and traces across services and UIs; define alert policies and on-call runbooks; help track SLOs and drive root-cause prevention.Security Fundamentals: Apply least-privilege access, secrets management, and encryption in transit/at rest; support secure-by-default patterns in API, SDK, and UI design.Quality & Tests: Write unit, integration, and end-to-end tests (for both backend and frontend); contribute to contract tests and data-quality checks where the app touches data pipelines.Collaboration & Documentation: Communicate clearly in writing and in person; produce concise docs (API specs, SDK docs, data contracts, feature runbooks, UI flows); work closely with product/engineering/analytics.Required Skills and QualificationsCore Engineering Experience: 5+ years building and operating web applications or SaaS products as a full-stack or backend engineer.Backend Expertise: Strong experience with at least one modern backend stack (e.g., Node.js/TypeScript, Python/FastAPI/Django, or similar); familiarity with REST best practices and common patterns.Frontend Proficiency: Proficiency with React and Next.js using TypeScript or JavaScript. Experience building reusable UI components and hooks, handling routing, data fetching, and basic performance tuning. Comfort designing and maintaining a frontend SDK (client library + components/hooks) that wraps backend APIs.APIs and Authentication: Practical experience with REST patterns, pagination, validation, rate limiting, and OAuth2/OIDC/JWT.Databases and SQL: Proficient in SQL (query tuning, indexing, query plans) and good RDBMS fundamentals (e.g., Postgres, SQL Server, MySQL); comfortable modeling application data.Data Engineering Exposure: Experience integrating with data pipelines or warehouses (e.g., consuming tables/views, working with ETL/ELT outputs, or equivalent exposure to data platform).Cloud Infrastructure: Strong experience with Azure or AWS (e.g., app hosting, storage, identity, monitoring - such as Azure App Service / Container Apps, API Management, Front Door, or AWS Lambda, ECS / Fargate, API Gateway, CloudFront, Cognito) and comfort navigating core services and IAM in at least one CSP.IaC and CI/CD: IaC fundamentals (Terraform is good, but Serverless Framework / CloudFormation / CDK, etc. are also acceptable); CI/CD experience (version control workflows, automated tests, environment promotion, release strategies).Testing Mindset: Habit of writing tests for backend and frontend code; comfortable with fixtures/test data and running tests in CI.Communication: Clear, concise writing and verbal communication; comfortable in async chat and live sessions.Ai Tooling: Ready to use Claude Code and/or GitHub Copilot from day one to accelerate work - while exercising judgment, understanding code deeply, and writing your own tests.PREFERRED QUALIFICATIONS (NICE TO HAVE)Data/Analytics Collaboration: Experience working closely with data engineering / analytics teams (e.g., defining data contracts, coordinating schema changes, supporting BI/analytics features).SDK and DX: Experience designing developer-friendly SDKs (clear APIs, good DX, documentation, versioning and deprecation strategies).Analytics Concepts: Exposure to analytics concepts (dim/fact modeling, event tracking, BI consumption patterns) and how product design affects them.Eventing and Messaging: Familiarity with event streaming/message queues (e.g., Kafka, Event Hubs, SQS/SNS) and when to use them vs. HTTP APIs.Data-Driven UIs: Experience with data-driven UIs (dashboards, reports, filters, exports) and performance considerations.Data Platform Awareness: Data platform architecture awareness (storage/layout choices, basic catalog/lineage/governance concepts) is a plus.Observability: Familiar with logs/metrics/traces, dashboards, and actionable alerts for both backend services and key frontend flows.Monitoring: Experience with cloud monitoring stacks (Azure Monitor/Application Insights, CloudWatch, Datadog, New Relic, etc.).Internal Tools: Comfort prototyping simple internal tools or admin panels using component libraries.
