Senior Software Engineer – Federal Systems

At MatrixSpace, we are building technology that bridges the physical and digital worlds — combining embedded systems, radar sensing, cloud computing, and AI to unlock powerful real-world intelligence.

We are seeking a Senior Software Engineer to join our Federal Systems team. This role supports the product across the product life cycle – including design, prototype implementation, field test, and productization. The ideal candidate brings strong hands-on experience across C/C++, Python, and embedded software, with exposure to Software-Defined Radio (SDR) platforms, secure communications, and ISR-relevant sensors. This requires technical depth, system-level thinking, and the ability to operate effectively in regulated and classified environments. The role is primarily onsite in Burlington, MA, with flexibility for hybrid work as project requirements allow.

### Key Responsibilities:

• Design, implement, and maintain embedded and real-time software systems.
• Extend commercial products to the military domain and austere environments.
• Use military domain knowledge to recommend software product improvements.
• Design, implement, and maintain different operating modes for the SDR: radar, EW, mesh comms, passive RF, etc.
• Integrate MatrixSpace sensor system data into commercial and military C2 systems, such as ATAK, FAAD-C2, Lattice, etc.
• Support hardware/software co-design, collaborating with electrical engineers on SoC, FPGA, PCB, and RF-adjacent systems.
• Develop operator, analyst, or engineering-facing tools, including GUI applications, visualization interfaces, and web-based dashboards.
• Participate in system integration, lab testing, verification, and validation, including hardware-in-the-loop testing and design of unique testing scenarios.
• Contribute to technical design reviews, requirements decomposition, and interface control documentation (ICDs).
• Support customer demonstrations, test events, and operational evaluations.
• Mentor junior engineers and contribute to engineering best practices within the Federal Systems team.

### Required Skills and Experience:

Candidates must be legally authorized to work in the United States without employer sponsorship and may be required to obtain and maintain a U.S. government security clearance in the future.

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or related discipline.
• At least 5 years of professional experience in embedded systems for federal, defense, aerospace, robotics, or sensing applications.
• Demonstrated proficiency for design, implementation, and maintenance of embedded and real-time software systems using C++, C, and Python for Linux-based embedded platforms, including ARM, SoC-based systems, GPU-accelerated edge devices, and FPGA-integrated architectures.
• Experience designing and performing tests to validate new software features at the unit level to system level.
• Experience using Git-based version control, Agile workflows, and CI/CD pipelines.
• Strong written and verbal communication skills.

### Preferred Skills and Experience:

We recognize that candidates may bring deep expertise in some areas and working knowledge in others. This role emphasizes embedded and sensor-facing software; experience in other areas is a plus but not required on day one.

• Experience with radar systems, RF signal processing, GPS/GNSS, or ISR platforms.
• Experience with distributed systems, REST APIs, WebSocket-based services, or data visualization pipelines.
• Experience writing and deploying containerized software with Docker and DevSecOps pipelines.
• Experience with outputs from convolutional neural networks (CNNs).
• Experience contributing to secure and mission-critical system design, including cryptographic interfaces, key handling workflows, and system hardening concepts.
• Previous experience evaluating and implementing RMF controls.
• Previous demonstrated integration of military C2 systems such as TAK, FAAD-C2, SAPIENT, Lattice, etc.
• Familiarity with MATLAB, simulation environments, and hardware-in-the-loop testing.

### Why Join Us

• Join a team that thrives on innovation and collaboration.
• Work on cutting-edge technology bridging embedded systems, cloud computing, and AI applications
• Collaborate with world-class engineers solving complex distributed systems challenges
• High ownership, fast iteration, and opportunities to lead architecture and innovation initiatives
• Competitive compensation, equity options, and a culture that values innovation and technical excellence.
