Senior Backend Engineer | Platform Quality
About The Position
Molecular You is a health tech company that turns complex biomarker science into actionable insight for everyday people. We're looking for a senior backend engineer to own platform quality — consistency across services, thoughtful tech adoption, security and compliance, and shipping things through to done. You'll also work closely with our scientific product manager to co-design new health report products, which means you'll need genuine curiosity about how biology works. You don't need a science degree — but if you've ever looked at your own lab results and wondered what they actually mean, that's the instinct.
Requirements
- Production experience with Ruby on Rails and Elixir/Phoenix — shipped and operated, not just familiar
- Distributed systems in practice: async messaging (RabbitMQ or similar), failure modes, idempotency, dead-letter queues
- Infrastructure ownership: Terraform and AWS at a level where you can drive a change, not just read one
- At least one example of reducing platform entropy — a migration, deprecation, or refactor that made a system class simpler, not just larger
- Experience owning a security or compliance decision end-to-end (HIPAA/PIPEDA context is a plus; the judgment is the requirement)
- Clear, direct communication — you can explain a technical trade-off to a scientific PM without either oversimplifying or retreating into jargon
Responsibilities
- Platform quality and consistency — you notice when two services handle errors differently and fix it, not file a ticket
- Thoughtful introduction of new technology — you're skeptical until it earns its place, then you drive adoption through
- Security and compliance balance — you've made design decisions where delivery and security were in tension, and you navigated them with judgment, not just caution
- Production improvements from diagnosis through to resolution — you close the loop
- New health report products developed alongside our scientific PM — from clinical question to shipped feature
Benefits
- Ownership of platform quality and engineering standards across a production health platform
- A role where your architectural decisions are load-bearing, and you'll know it
