As a Software Engineer at Innoflight, your day-to-day work will involve a mix of individual coding, system integration, and cross-functional collaboration. You will be responsible for the entire software lifecycle, from initial architectural design to final hardware-in-the-loop validation.

Your primary responsibilities will include:

• Designing and developing reliable, deterministic embedded software and firmware in C and C++ for flight computers, software-defined radios, and digital modems.
• Collaborating closely with FPGA, hardware, and systems engineers to define hardware-software interfaces, register maps, and communication protocols.
• Implementing and optimizing digital signal processing (DSP) algorithms to run efficiently on embedded microprocessors and microcontrollers.
• Writing comprehensive unit tests, integration tests, and hardware-in-the-loop (HIL) test suites to validate software performance against strict aerospace requirements.
• Participating in design reviews, documenting software architectures, and ensuring compliance with industry and military standards for safety and reliability.

To be competitive for a Software Engineer position at Innoflight, you must possess a strong foundation in both software engineering principles and hardware concepts. The ideal candidate enjoys working close to the metal and has a proven track record of delivering reliable embedded systems.

• Must-have skills – Strong proficiency in C or C++ programming for embedded systems, experience working with real-time operating systems (RTOS) or bare-metal environments, and a solid understanding of low-level hardware interfaces (such as SPI, I2C, UART).
• Nice-to-have skills – Experience with FPGA design (using VHDL or Verilog), familiarity with digital signal processing (DSP) concepts, experience with MATLAB/Simulink for system modeling, and a background in aerospace or defense electronics.
• Experience level – Typically requires a Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field, along with several years of hands-on experience in embedded software development.
• Security and Location – Due to the nature of defense contracts, candidates must typically be US citizens capable of obtaining a security clearance, and willing to work onsite or in a hybrid capacity at the San Diego, CA facility.

Q: How technical is the take-home test, and what does it evaluate? The take-home test is highly practical and directly reflects the type of work you will do at Innoflight. It evaluates your ability to write clean, modular, and well-documented C/C++ code, your attention to edge cases, and your understanding of embedded system constraints. Treat it as a production-level deliverable.

Q: What is the company culture like for engineers? The engineering culture is highly collaborative, technical, and mission-focused. Because the systems being built are destined for space, there is a strong emphasis on quality, rigorous peer reviews, and cross-disciplinary communication.

Q: How long does the entire interview process take? The process typically takes about three to four weeks from the initial recruiter contact to the final offer, depending on how quickly you complete and submit the take-home technical test.

Q: Is remote work available for this position? Because the role involves significant hardware-software integration, testing with physical equipment, and collaboration with hardware and FPGA teams, most engineering roles require a consistent onsite presence at the San Diego, CA office, though some hybrid flexibility may be available depending on the team.

To maximize your chances of success during the Innoflight interview process, keep the following practical tips in mind:

• Brush up on hardware fundamentals: Even if you are applying for a pure software role, be ready to discuss basic hardware concepts. Understanding how a processor interacts with memory, how interrupts work, and how data flows across a serial bus will set you apart.

• Showcase your testing philosophy: Don't just talk about how you write code; explain how you prove that your code works. Highlight your experience with unit testing, integration testing, and hardware-in-the-loop validation.
• Be prepared for a direct interview style: Some technical interviewers may have a very direct, no-nonsense communication style. Remain confident, focus on the technical details of your answers, and don't hesitate to ask clarifying questions if a scenario is ambiguous.
• Document your take-home code thoroughly: When completing the technical test, write clean code and include clear documentation explaining your design choices, assumptions, and how to build and run your tests. This demonstrates professionalism and respect for the reviewer's time.

A Software Engineer position at Innoflight offers an exceptional opportunity to build software that operates in the challenging environment of space. By preparing thoroughly for evaluations in embedded systems, digital communications, and hardware integration, you can position yourself as a strong candidate for this highly impactful role.

Focus your preparation on mastering low-level C/C++ concepts, understanding the nuances of real-time operating systems, and practicing how you would explain complex hardware-software debugging scenarios. Remember that the hiring team values practical execution, attention to detail, and a collaborative mindset just as much as theoretical knowledge.
