Clarity is redefining customer experience with AI. Our mission is to empower businesses to deliver faster, smarter, and more human service interactions. By combining cutting‑edge AI with intuitive design, we enable customer service teams to operate more efficiently while providing customers with seamless, personalized experiences.
As a Full‑Stack Web Developer at Clarity, you’ll own end‑to‑end product surfaces—from sleek React UIs to FastAPI services and Elasticsearch—shipping fast, safely, and beautifully. You’re AI‑native, comfortable in both AWS and GCP, and you treat infra & DevOps as part of building great product, not an afterthought. You’ll collaborate directly with engineers, PMs, and the CTO to turn specs into production features used by brands like Grubhub, Booking, Dropbox & Uber.
What you'll do
- 50% Build — design & ship
- Build responsive React (TypeScript) frontends (state management, data visualisation, virtualised tables, forms, charts, file uploads, accessibility).
- Implement FastAPI services (async I/O, Pydantic v2, background jobs, caching) with robust testing.
- Design Elasticsearch models & queries.
- Integrate AI features (streaming responses, structured outputs, eval hooks) to accelerate prototyping and user value.
- 25% Scale & operate
- Ship and run services on AWS and/or GCP (ECS/EKS/Lambda or Cloud Run/GKE), containerised with Docker.
- Own CI/CD (GitHub Actions), IaC (Terraform), logging/metrics/tracing (OpenTelemetry, CloudWatch/Stackdriver, Grafana/Prometheus), and SLOs.
- Optimise p95 latency, throughput, and cost; manage secrets, networking, VPCs, and build resilient retries/backoffs.
- 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.
- AI‑native builder: Cursor, v0, Claude Code are daily drivers for rapid prototyping and refactors.
- React + TypeScript mastery: component design, hooks, performance, testing (Vitest/Jest, Playwright).
- FastAPI expertise: async patterns, Pydantic schemas, pagination, auth (OAuth2/OIDC), rate‑limits, background jobs.
- Elasticsearch fluency: mappings/analyzers (ngrams, synonyms), aggregations, filters, sorting, performance tuning.
- Cloud & DevOps: solid experience on AWS and/or GCP, Docker, Terraform, GitHub Actions, monitoring/alerts.
- Datastores: Postgres (SQL, migrations), Redis (caching/queues).
- Quality & security: code reviews, type safety, lint/format, secrets management, least‑privilege IAM, basic SOC2 hygiene.
- Communicates clearly with product sense; ships value weekly.
Perks and bonuses
- Remote‑first freedom & flexible hours.
- Regular off‑sites & monthly virtual game nights.
- Unlimited vacation (minimum 20 days encouraged).
- Learning budget for conferences, courses & books.
- Startup equity in a rapidly growing market.
