Clarity - Web: Full Stack Tech Lead

• 50% Build — design & ship • Build responsive React (TypeScript) frontends (state mgmt, data viz, virtualized tables, forms, charts, file uploads, accessibility). • React (TypeScript) • Implement FastAPI services (async I/O, Pydantic v2, background jobs, caching) with robust testing. • FastAPI • Design Elasticsearch models & queries • Elasticsearch • Integrate AI features (streaming responses, structured outputs, eval hooks) to accelerate prototyping and user value. • 25% Scale & operate • 25% Scale & operate • Ship and run services on AWS and/or GCP (ECS/EKS/Lambda or Cloud Run/GKE), containerized with Docker. • AWS and/or GCP • Own CI/CD (GitHub Actions), IaC (Terraform), logging/metrics/tracing (OpenTelemetry, CloudWatch/Stackdriver, Grafana/Prometheus), and SLOs. • CI/CD • OpenTelemetry • Optimize p95 latency, throughput, and cost; manage secrets, networking, VPCs, and build resilient retries/backoffs. • p95 latency, throughput, and cost • 15% Collaborate • 15% Collaborate • Work closely with design/PM on specs and UX polish; pair with back-end/ML on data contracts and APIs. • Partner with the Insights team on taxonomy/schema changes and with Data/ML on search & analytics expectations. • 10% Align & showcase • Write crisp docs, PRDs/tech notes, and demo your work to execs & customers. • Contribute to on-call for your services and drive post-mortems to closure. • What makes you a great fit • Owner’s mindset: you take ideas from zero → shipped → observed → iterated; you sweat details and outcomes. • Owner’s mindset • AI-native builder: Cursor, v0, Claude Code (and friends) are daily drivers for rapid prototyping and refactors. • AI-native builder • React + TypeScript mastery: component design, hooks, performance, testing (Vitest/Jest, Playwright). • React + TypeScript • FastAPI expertise: async patterns, Pydantic schemas, pagination, auth (OAuth2/OIDC), rate-limits, background jobs. • FastAPI • Elasticsearch fluency: mappings/analyzers (ngrams, synonyms), aggregations, filters, sorting, performance tuning. • Elasticsearch • Cloud & DevOps: solid experience on AWS and/or GCP, Docker, Terraform, GitHub Actions, monitoring/alerts. • Cloud & DevOps • AWS and/or GCP • Datastores: Postgres (SQL, migrations), Redis (caching/queues). • Datastores • Quality & security: code reviews, type safety, lint/format, secrets mgmt, least-privilege IAM, basic SOC2 hygiene. • Quality & security • Communicates clearly with product sense; ships value weekly.
