Job Summary
Build the Future of Wellbeing
Do Your Lifes Best Work
If modern wellbeing were redesigned from scratch it wouldnt live in a GPs office or a cluttered supplement aisle. It would be digital-first beautifully curated and powered by data that actually helps you feel your best.
Thats what were building at Healf. An ecommerce platform at the intersection of personalised health and curated wellbeing. We connect customers with the worlds most effective products across EAT MOVE MIND and SLEEP and were just getting started.
We combine culture-shaping storytelling cutting-edge health tech (like our new blood testing platform Healf Zone) and a best-in-class product experience to help people build rituals that work.
Backed by investors behind Soho House Alo Yoga Cult Beauty and Innocent were scaling fast and redefining how the world shops and lives well.

The Role
Were scaling rapidly across Web/Frontend and Backend/AI. To keep pace we need a hands-on technical leader who can balance deep execution with architectural foresight. Youll bridge strategy and implementation: co-creating architecture and engineering standards with the Head of Engineering while directly leading teams to build systems that scale sustainablywithout bottlenecks.
Where Youll Make An Impact
Build high-throughput asynchronous APIs and microservices in Python with FastAPI.
Design and evolve Postgres schemas migrations and performance tuning (query plans indexes connection pooling).
Implement authentication/authorisation (OAuth2/JWT) input validation rate-limiting and robust error handling.
Add observability for services: structured logging tracing metrics and actionable dashboards/alerts.
Design scalable secure AWS infrastructure (ECS/EKS Lambda ElastiCache S3 DynamoDB) using infrastructure-as-code preferably Pulumi.
Ship via containerized CI/CD (GitHub Actions ArgoCD) with automated tests blue-green/canary deployments and rollbacks.
Collaborate with product and design to turn requirements into well-scoped production-ready features; write clear docs and participate in code reviews.
What Youll Bring
5 years backend Python experience building production services and APIs.
Mastery of async Python patterns (asyncio uvicorn pydantic v2) and strong typing discipline.
Hands-on experience architecting cloud-native horizontally scalable systems on AWS.
Deep familiarity with Postgres (schema design performance resilience) and ORMs (e.g. SQLAlchemy or equivalent).
Solid grounding in DevOps practices: IaC (Pulumi or Terraform) automated testing (pytest) security scanning and performance profiling.
Nice to Have (Not Required):
Experience with FastAPI dependencies background tasks and websockets at scale.
Caching and messaging (Redis/**ElastiCache** SQS/SNS Kafka).
Exposure to LLM tooling (e.g. LangChain) and retrieval patterns (embeddings/RAG) useful but not required.
Working knowledge of ML concepts and/or model training pipelines (bonus only).
