What You'll DoAs our Staff Firmware Engineer, you'll serve as a principal technical authority - shaping the firmware architecture, driving strategic initiatives, and mentoring the broader engineering team - while remaining deeply hands-on in the development of next-generation Class III active implantable devices:
- Set technical direction - Define and own the long-range firmware architecture, partnering with technical leadership to drive the roadmap and set engineering standards across embedded subsystems.
- Deliver safety-critical firmware - Lead design, implementation, and verification of firmware for power management, ASIC interfaces, BLE communication stacks, and security subsystems, with an uncompromising focus on safety and correctness.
- Own BLE security - Drive BLE security architecture from the ground up - including secure pairing/bonding, AES-CCM encryption, MITM protection, secure key storage, and firmware signing - establishing iota's security posture for connected implantable devices.
- Enable innovation and quality - Integrate and debug complex subsystems, lead root-cause investigations, and support reliability, verification, and compliance activities aligned with IEC 62304 and related medical device standards.
- Elevate the team - Serve as a technical mentor and collaborator across mechanical, electrical, systems, and quality teams, as well as external partners, from concept through clinical readiness.
Responsibilities:- Architect and lead the development of embedded software for iota's devices across the full product lifecycle, defining patterns and standards for the firmware team.
- Own the BLE security posture for iota's connected implantable devices: design and implement secure pairing/bonding, AES-CCM encryption, MITM protection, secure key storage, and firmware signing; establish threat models and drive security reviews.
- Optimize RF/BLE power delivery and control systems on embedded platforms; apply modern software techniques to support multiple products while maximizing reuse.
- Collaborate with software engineers to design the data infrastructure for efficiently routing all required data from embedded processors to application software, cloud backend, and configuration services.
- Lead and own the process of verifying embedded software to medical regulatory standards, maintaining an industry-leading development pace.
- Elevate team software development processes and infrastructure, including DevOps activities, code review standards, and onboarding of junior engineers.
What you'll bring:- B.S. in Computer Science, Electrical Engineering, or related field with 10+ years of industry experience programming in C/C++
- OR M.S. in Computer Science, Electrical Engineering, or related field with 8+ years of industry experience programming in C/C++
- Demonstrated BLE security experience - pairing/bonding procedures, AES-CCM encryption, MITM protection, secure key storage, and firmware signing
- Deep expertise in Real-Time OS (RTOS) for embedded platforms
- Extensive experience with Bluetooth Low Energy (BLE) protocol stacks and wireless communication subsystems
- Proven track record of leading firmware architecture decisions and mentoring engineers across a team
Preferred qualifications:- Experience with test automation tools (e.g., Jenkins) and modern software test/deployment methodologies
- Comfortable working in a Python environment for tests and prototyping
- Substantial experience with ISO 13485 (QMS), ISO 14971 (risk management), and/or IEC 62304 (medical device software)
- Experience authoring technical design documentation, threat models, and security risk assessments
- Prior experience in Class II/III medical device development or other highly regulated embedded domains
