Senior Software Engineer II, Internal Systems

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.

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.

As a Senior Software Engineer II, Internal Systems at Biofire, you will play a pivotal role in developing Biofire's internal systems. You will own Biofire’s internal systems architecture end-to-end, partnering closely with system owners and cross-functional stakeholders to understand how our systems work today and where they break down. This role is accountable for turning ambiguity into a clear current-state map, a prioritized roadmap with measurable outcomes, and working MVPs that remove meaningful manual work and close critical data and traceability gaps. You’ll connect heterogeneous systems through production-grade integrations that hold up under real operations, while improving the stability and effectiveness of existing workflows during buildout and delivering a pragmatic migration strategy.
Success requires high autonomy, evidence-based problem solving, strong technical writing, and a security-by-default mindset.

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

• Take ownership of internal systems end-to-end: understand current architecture, workflows, and operational constraints by working directly with existing system owners;

• Assess the internal systems landscape to produce a prioritized plan (technical debt, risks, and velocity blockers across access/tooling/resourcing), align stakeholders on the roadmap, and document decisions and tradeoffs clearly;

• Ship a small set of high-impact MVPs that reduce manual work and close data/traceability gaps, and quantify outcomes with meaningful operational metrics;

• Design and implement resilient integrations across heterogeneous systems (API/event/batch), with observability that supports real operations;

• Improve stability of existing workflows during buildout, and deliver a pragmatic migration strategy aligned to the roadmap.

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 ownership of internal systems architecture end-to-end, delivering working solutions across a mixed buy/build stack with strong prioritization and iterative execution;

• Proven experience integrating enterprise systems across business and operations (e.g., inventory, manufacturing execution, product lifecycle, customer systems) and delivering production-grade API/event/batch workflows that stay reliable under real operations, using patterns like idempotency and robust retry/recovery;

• Proven ability to design end-to-end workflows and maintain consistency across systems of record using canonical IDs, lifecycle/state models, and approaches that resolve “systems disagree” failures;

• Strong technical writing and stakeholder alignment skills, including documenting decisions, risks, dependencies, and tradeoffs clearly;

• Comfort bridging business systems with manufacturing and operations realities, including uptime/cycle-time sensitivity and traceability needs.

In addition to competitive pay, as a full-time employee at Biofire you are eligible for:

• Stock Options in Biofire, 401(k), HSA - and other financial benefits

• Medical Insurance - including plan options with $0 payroll deduction

• Dental, Vision and Life Insurance Plans - with $0 payroll deduction

The compensation range for this role is $180,000 - $210,000/annual salary + stock options + benefits.

Pay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience. The total compensation package for this position may also include other elements dependent on the position offered. Details of participation in these benefit plans will be provided if an employee receives an offer of employment.

This is a full-time, salaried role. Our dog-friendly, state-of-the-art headquarters is located in beautiful Broomfield, Colorado, between Boulder and Denver. The team regularly engages in collaborative in-person sessions at our vibrant office space, but you will be offered the flexibility to work from home as needed.
We expect you to bring your very best, and in return, we will provide the support necessary for you to excel. You'll collaborate with colleagues you appreciate, respect, and find inspiration from, and have access to all the technical resources needed.

We’re bringing innovation to a technological problem that has persisted for decades, so we depend on diverse, inclusive, and collaborative teams to break new ground and do great work.
