Job description

Forj Medical designs and develops custom electromechanical devices driven by safety-critical embedded software. We work in 4 major Technology Segments: Fluid & Gas Management, Optical Systems, Surgical Energy and Stimulation/Active Wearables. Our projects typically involve 'greenfield', bespoke designs - giving our engineers both depth and breadth in design challenges - opportunities to learn & grow abound.

What you'll do

As a Principal Software Engineer at Forj, you'll be one of our most trusted technical leaders—helping teams turn our clients' most difficult medical-device challenges into safe, secure, and maintainable embedded software. You'll combine deep hands-on engineering with broad influence: shaping product and platform architectures, guiding critical technical decisions, and raising the quality of software work across projects. You'll work with significant autonomy, but not alone—partnering closely with clients, program leaders, and engineers across systems, electrical, mechanical, test & quality.

Core responsibilities include:

• Applying expert knowledge of the Forj Quality Management System, FDA regulations, IEC 62304, and cybersecurity standards to software system development.
• Proactively identifying the highest technical and program risks early; evaluating alternatives, making thoughtful tradeoffs, and communicating recommendations clearly to technical and nontechnical stakeholders.
• Leading requirements definition, architectural design, and technical decision-making across software-intensive medical device systems.
• Providing detailed estimates in support of project milestones and software deliverables; delivering medium to highly complex software projects within scope, schedule, and budget constraints.
• Applying a unique feature-focused method of breaking down software system functionality; you'll iteratively lead your software team through architecture, design, implementation, testing and integration of software features in an agile workflow.
• Leading and mentoring a team of software engineers through work planning, task delegation, and coordination of execution.
• Design, implement and test project source code, especially in critical areas, including debugging difficult system issues, navigating integration challenges, and demonstrating effective engineering practices.
• Owning the technical quality of all software artifacts – ensuring architectural integrity, code quality and design robustness.
• Driving software process improvements, reusable platforms, and engineering initiatives that benefit multiple projects.
• Serving as a trusted advisor to clients, engineering leadership, and cross-functional teams on high-impact technical decisions.

You'll have a chance to make a meaningful impact on the lives of patients – our recent products help clinicians treat cancer, sustain life and alleviate pain.

To top it off, we think you'll enjoy working with other smart, curious and talented engineers as you bring medical devices to life.

What you bring

• BS, MS, or equivalent degree in Computer/Software Engineering, Computer Science or similar field.
• 10+ years' experience in embedded software development in medical device or other regulated industry, including in a lead role with a track record of successful software delivery using an inspirational and effective leadership style.
• A record of technical leadership on complex products or platforms, with influence extending beyond a single feature or project team.
• The ability to create clear technical narratives and diagrams, explain difficult concepts to varied audiences, and build trust with clients, peers, and leaders.
• Significant experience with embedded Linux development on SoMs – particularly with Yocto Project/BSP and driver configuration.
• Deep expertise in embedded software architecture, design, implementation, integration, and test using C and/or C++; experience with C#, Python, or other supporting languages is helpful.
• Demonstrated proficiency in solving high-complexity software problems – including a methodical, reasoned approach to reproducing and fixing bugs.
• Strong experience with microcontrollers, RTOS-based systems (e.g. ThreadX), device drivers, interprocess or interprocessor communications, and hardware/software integration.
• Experience with one or more of the following: communication protocols; Qt/QML, LVGL or other GUI frameworks; automated builds and CI/CD; static analysis; Python or other scripting languages; medical-device cybersecurity.
• Experience creating reusable software components, influencing engineering practices across teams, evaluating shared technologies, or contributing to proposals and technical strategy is especially valuable.
