Software Engineer, Web Application

JOB SUMMARY Iambic is building a secure, cloud-based platform for running our ML-driven drug-discovery workflows. You'll own and evolve our web application - the primary surface through which scientists interact with our drug-discovery platform. You'll work across the full stack, from the interface through the FastAPI HTTP layer down to the service layer, building features that are usable by non-engineers (chemists, biologists) and trustworthy with sensitive scientific data. This role suits an engineer who enjoys shipping end-to-end features on a product surface, cares about UX for a technical-but-non-developer audience, and is comfortable that the web layer is a thin, secure adapter over a shared service layer rather than a place for business logic. This position is based out of our new Ireland office. KEY RESPONSIBILITIES - Build and evolve a Python web application - its interface, the API layer behind it, and the supporting workflows. - Work across the stack: server-rendered UIs (HTMX), FastAPI route handlers, and the underlying service layer. - Work with domain experts (primarily chemists and biologists working on drug discovery projects) to understand requirements. - Design interfaces that are usable and legible for non-engineers; contribute to onboarding materials and in-product guidance. - Keep the web/HTTP layer a thin contract over the service layer - no business logic in route handlers - so the same logic is reusable by future entry points. - Treat sensitive data with care: enforce authorization and access scoping on every request, and surface clear, safe error states rather than silent failures. - Participate in design discussions, code reviews, and documentation. QUALIFICATIONS - Strong full-stack engineering skills with production Python, including building server-rendered UIs (e.g. HTMX). - Experience building and operating production web applications or SaaS-style products. - Comfort with HTTP API design and well-structured backend services (FastAPI or similar). - Experience with relational databases. - A track record of building usable interfaces for real users and iterating on feedback. - Comfortable working closely with scientific or domain users on data-intensive problems. - Awareness of web security fundamentals (authn/authz, session handling, handling sensitive data) preferred - Familiarity with containerization and CI/CD preferred. - Strong written communication and the ability to work effectively in a distributed team. TECH STACK & ENVIROMENT - Python with modern tooling (e.g. uv, pixi) - FastAPI with a clean service-layer architecture - Server-rendered UIs (HTMX) - PostgreSQL and object storage (S3) - AWS (ECS and related services) - Infrastructure-as-code and automated CI/CD; containerized services - Agentic coding tools (e.g. Claude Code) as part of day-to-day development ABOUT IAMBIC THERAPEUTICS Iambic is a clinical-stage life-science and technology company developing novel medicines using its AI-driven discovery and development platform.
