Senior Software Engineer II, Web Platform

WHO WE ARE

Biofire Technologies is on a mission to give gun owners better tools for reducing preventable gun injuries and deaths, especially among children. We believe our technology, combined with a best-in-class customer experience, will define the future of firearms safety for the next generation. Our mission-driven approach has earned support from the firearm community, the tech world, and the media. Biofire employees encompass a diverse range of talents, including world-class engineers who have designed and tested firearms, medical devices, robots, cars, satellites, rockets, and supersonic jets; expert technicians from aerospace, defense tech, special forces, and gunsmithing; and elite operators from high-tech, advanced manufacturing, and regulated industries. Whether building the product or powering the company behind it, every Biofire team member is united by an obsession with safety, reliability, and operational excellence.

OUR CULTURE

Reducing accidental firearm injuries and deaths requires original thinking and authentic collaboration, so we’re deeply invested in building a team and culture that can achieve our mission together. Team members enjoy autonomy and flexibility from day one, so expect to be immediately tasked with solving challenging problems and building new systems that work. We’ll hold you accountable for executing audacious goals, giving and receiving honest feedback, and helping your teammates succeed. You’ll receive respect, kindness, and support from every direction while you figure out how to get it all done.

ABOUT THE ROLE

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.

KEY RESPONSIBILITIES

Day-to-day responsibilities of the role will include:

• Design, build, and ship changes across the full stack — frontend, API, data, and infrastructure — without needing a specialist at any layer;

• Own Biofire's customer-facing web platform end to end: assess the current architecture, set a pragmatic technical roadmap that supports the company's digital growth, and personally build the changes it calls for;

• Build platform capabilities that enable self-service digital marketing, including CMS-driven content publishing, analytics pipelines, and experimentation infrastructure;

• Improve platform reliability and observability, establishing dashboards, alerting, and SLOs for critical user journeys such as auth, checkout, and account access;

• Strengthen release infrastructure so the team can deploy to production frequently and with confidence;

• Plan and roll out architectural changes deliberately, weighing the potential impact of each change and documenting the rationale for major decisions;

• Partner with Marketing, Design, and CX to surface technical constraints early, propose practical alternatives, and define clear ownership boundaries between engineering and stakeholder teams.

QUALIFICATIONS

We understand that not all applicants will possess skills that perfectly align with our job qualifications. At Biofire, we appreciate diverse experiences from various industries, and we encourage all individuals who meet the necessary qualifications to submit their applications. While having the "desired" qualifications may strengthen a candidate's profile, we also welcome applicants with alternative experiences to apply.

• Demonstrated end-to-end ownership of production web platforms across multiple projects or problem domains;

• Proven full-stack fluency across the modern web stack (Next.js, TypeScript, React, Prisma, GraphQL) including the operational layer — deployment, CI/CD, auth, CMS integration, and payment processing;

• Strong system design instinct, including the ability to spot structural weaknesses in a production codebase and its deployment pipeline and address them without introducing new risk;

• Track record of shipping quickly and delivering work that holds up over time without a tail of rework;

• Comfort operating in a commerce- and regulatory-heavy domain where data correctness is non-negotiable, including orders, payments, and regulated inventory state;

• Strong cross-functional partnership skills: clear recommendations, honest and early communication, and reliable delivery with non-engineering stakeholders.
