Senior Software Engineer II, Web Platform

As Senior Software Engineer II, Web Platform at Biofire, you will take ownership of the platform behind our customer-facing website — the system of record for everything from browsing and account access to checkout on a regulated product. You'll start by getting to know the stack inside and out: assessing its architecture, integration points, and technical debt, then turning that assessment into a pragmatic roadmap for how the platform needs to evolve to support Biofire's growing digital marketing efforts and rising traffic.

From there, you'll build the platform capabilities that let Marketing move independently — self-service content publishing, analytics, and experimentation infrastructure — while also raising the bar on reliability: consolidating observability, setting clear SLOs for critical journeys like authentication and checkout, and strengthening release infrastructure so the team can ship frequently and with confidence. This is a full-stack, full-ownership role: you'll work across frontend, API, data, and infrastructure, and partner closely with Marketing, Design, and CX to keep the platform's evolution grounded in what the business actually needs.
