Software Engineering Intern

Astro Mechanica is a vertically integrated aerospace company developing a scalable technology platform to power critical infrastructure, mission operations, and the future of flight. We apply aerospace engineering and quality standards across our products, delivering high performance, reliability, and efficiency for the most demanding operating environments. Astro Mechanica is backed by leading venture and strategic investors, including Andreessen Horowitz (a16z), Giant Step Capital, United Airlines Ventures, and Voyager Ventures.

We’re a team of passionate engineers dedicated to advancing aerospace. We’re generalists with specialist depth, united by a flat structure and a shared obsession with building things that work well. We move fast, stay pragmatic, and let engineering excellence speak louder than hierarchy.

Astro Mechanica is seeking an intern to join our Software Engineering Team for the summer of 2027 (program begins on June 7, 2027 for semester schools and June 27, 2027 for quarter schools). This is not a sandbox internship. You’ll be embedded with the team in our San Francisco office, working on real projects that ship and contribute directly to our hardware and flight programs. The ideal candidate is curious, learns quickly, and is excited to write software that touches real aircraft systems. You’ll work alongside full-time engineers, take part in design discussions and code reviews, and own meaningful pieces of work from start to finish. Your work will move fast in a dynamic startup environment and will have a direct impact on our mission.

• Work as an embedded member of the software team, joining standups, design reviews, and planning alongside full-time engineers

• Own a scoped, real-world project from design through implementation, testing, and delivery, with mentorship from senior engineers

• Contribute to flight software, simulation, test infrastructure, or internal engineering tools

• Test your code on real flight hardware (flight computers, embedded microprocessors, engine hardware)

• Write clean, testable, and maintainable code, including unit and integration tests

• Collaborate with mechanical, electrical, propulsion, and controls engineers to understand software requirements

• Debug issues across the stack and learn how software integrates with embedded and real-time systems

• Present your work to the team at the end of the summer

• Currently pursuing a Bachelor’s, Master’s, or PhD in Computer Science, Engineering, Math, or a Science discipline

• Experience with C++, Rust, Python, or another programming language, through coursework, projects, research, or prior internships

• Solid fundamentals in data structures, algorithms, and object oriented programming

• Familiarity with version control (Git) and software testing practices

• Ambition to work in a fast-paced environment and take ownership of your work

• Available for a full-time, in-person internship in San Francisco during Summer 2027 (approximately 10–12 weeks)

• Competitive hourly pay

• Hands-on mentorship from experienced engineers

• Company-funded perks, including team lunches, game nights, and other activities

At Astro Mechanica, we highly value in-office work to foster collaboration and strengthen our company culture. We consider working in the office five days a week an essential part of the employee's role.

Astro Mechanica is an equal opportunity employer. We proudly recruit and hire a diverse workforce and are committed to creating an inclusive environment for all employees.
