Job summary

Heaviside Industries, Inc. is seeking an experienced software engineer to develop robust C/C++ and Python software for autonomous precision munitions in Linux/RTOS environments.

You will collaborate with electrical, mechanical, RF, and systems engineers to take capabilities from prototype to production, building interfaces to sensors, radios, actuators, and cameras. The role emphasizes fast iteration through simulation, hardware-in-the-loop testing, and streamlined CI processes.

Qualifications

• Strong proficiency in C and C++, with Python experience for tooling or integration.
• Hands-on embedded Linux or RTOS, cross-compilation, hardware/software debugging.
• Experience with UART, SPI, I2C, CAN, Ethernet and network programming.
• Experience integrating sensors, radios, actuators, or hardware into production/field systems.
• Familiar with Git and collaborative software development workflows.

Responsibilities

• Write robust C, C++, and Python for real-time, resource-constrained environments on Linux/RTOS.
• Collaborate with electrical, mechanical, RF, and systems engineers to move capabilities from prototype to production.
• Design and maintain software for autonomous systems including embedded and mission software.
• Build interfaces to sensors, radios, actuators, cameras and other hardware; validate on bench and in field.
• Develop simulation, hardware-in-the-loop, and automated test infrastructure for rapid iteration.
• Support integration campaigns and field-test events with debugging on live hardware.
• Contribute to lightweight engineering practices: code review, CI, and pragmatic documentation.

Job description

ABOUT HEAVISIDE INDUSTRIES

Heaviside Industries builds multi-domain autonomous precision munitions for U.S. and allied special operations and conventional forces. While modern warfare has rapidly evolved with the proliferation of unmanned systems, hyper-precise munitions in contested environments are the future of the battlefield. Economical precision strike capabilities are critical to U.S. and allied war efforts, enabling successful defeat of enemy military assets and infrastructure. Heaviside builds precision munitions designed to operate in GPS-denied and spectrum-jammed battlefields—where traditional systems degrade or fail—without inflated prices or sacrifice to performance.

All engineering and manufacturing is conducted in-house in Heaviside's Los Angeles, CA headquarters and Oslo, Norway office.

Heaviside is backed by Felicis, Hedosophia, Interlagos, Friends & Family Capital, Menlo Ventures, Flume Ventures, Cantos, and others.

WHAT WILL YOU DO

• Write robust C, C++, and Python for resource-constrained, real-time environments on Linux and RTOS targets.
• Work directly with electrical, mechanical, RF, and systems engineers to take new capabilities from prototype to production.
• Design, implement, and maintain software for autonomous systems, including embedded software, mission software, and supporting ground tools.
• Build and own software interfaces to sensors, radios, actuators, cameras, and other hardware; validate them on the bench and in the field.
• Develop simulation, hardware-in-the-loop, and automated test infrastructure that lets the team iterate quickly with confidence.
• Support integration campaigns and field-test events, including debugging on live hardware and turning findings into fixes.
• Contribute to engineering practices that keep a small team fast: code review, CI, and pragmatic documentation.

WHAT WE ARE LOOKING FOR

• 5+ Years of experience
• Strong proficiency in C and C++, with practical Python experience for tooling, automation, or system integration.
• Hands-on experience with embedded Linux and/or real-time operating systems, cross-compilation, and debugging at the hardware/software boundary.
• Knowledge of common hardware interfaces such as UART, SPI, I2C, CAN, and Ethernet, along with network programming fundamentals.
• Experience integrating sensors, radios, actuators, or other hardware into a production or field-tested system.
• Experience with Git, code review, and collaborative software-development workflows.
• Comfort operating with ambiguity in a small, fast-moving team.
• U.S. Person as defined by ITAR (22 CFR §120.62)

NICE TO HAVE

• Nix or NixOS experience, particularly reproducible development or deployment environments.
• Ability to use oscilloscopes, logic analyzers, JTAG/SWD debuggers, and serial-console tooling.
• Experience with autonomy, robotics, controls, estimation, navigation, signal processing, communications software or ROS.
• Experience with simulation, hardware-in-the-loop testing, automated test infrastructure, or hardware bring-up.
• Experience developing SDKs, libraries, or interfaces used by other engineering teams.

Additional:

Compensation bands are determined by role, level, location, and alignment with market data. Individual level and base pay is determined on a case‑by‑case basis and may vary based on job‑related skills, education, experience, technical capabilities and internal equity. In addition to base salary, for full‑time hires, you may also be eligible for long‑term incentives, in the form of stock options, and access to medical, vision & dental coverage as well as access to a 401(k) retirement plan.

Heaviside will consider qualified applicants with criminal histories, including arrest or conviction records, consistent with the City of Los Angeles Fair Chance Initiative for Hiring Ordinance, the Los Angeles County Fair Chance Ordinance for Employers, and the California Fair Chance Act. Heaviside intends to review criminal history after a conditional offer. Heaviside reasonably believes criminal history may have a direct, adverse, and negative relationship with the following duties, potentially resulting in withdrawal of the offer: (1) accessing export‑controlled technical data and defense articles; (2) handling and maintaining inventory of controlled components, tools, and equipment; and (3) accessing secure facilities, laboratories, and field test sites.
