About Revolution Space

We are building advanced space systems for the 21st century. Every employee works on projects that are critical to our company’s future by ensuring our products work on orbit every time.

Position Summary

We are looking for an experienced, dynamic, growth-oriented Software Test Engineer to contribute to the development of our space propulsion products through system verification. This engineer will integrate with the existing technical team to:

• Execute testing, debugging, and troubleshooting of software applications
• Collaborate with other members of the software team including developers and system engineers
• Work full‑time remotely or in a hybrid role in Boston, MA or Lanham, MD

Responsibilities

• Design, document, and execute comprehensive test plans (unit, integration, and system‑level) and procedures for flight and ground software.
• Perform validation of Flight and Ground SW functional tests at the unit, integration, system, and acceptance levels.
• Validate embedded software via test automation where possible.
• Ensure software compliance through hardware‑in‑the‑loop (HITL) or simulation‑in‑the‑loop (SITL) with actual hardware endpoints or avionics rigs as needed.
• Verify system, subsystem, and component‑level requirements for space system interfaces with spacecraft power, thermal, and command & data handling subsystems.
• Communicate with software developers and engineers to verify requirements, review code, and implement testability features.
• Identify, develop, maintain, and utilize automated test scripts within a continuous integration (CI) environment where possible.
• Manage requirement traceability (requirements design verification) in tools such as MS Excel, DOORS, or equivalent.
• Lead or support verification planning and closure activities, including verification‑by‑analysis, similarity, inspection, test, and demonstration.
• Collaborate closely with propulsion design engineers, test engineers, and mission assurance teams to define test objectives, success criteria, and acceptance plans for vacuum chamber, thermal‑vacuum, and life‑cycle testing.

Required Qualifications

• Bachelor’s degree in computer science/engineering, aerospace engineering, mechanical engineering, electrical engineering, physics, or related discipline.
• 7+ years of total experience with a minimum of four years in software testing, preferably in aerospace.
• Familiarity with verification and validation (V&V) processes in aerospace or high‑reliability industries.
• Working knowledge of requirement management tools (MS Excel, DOORS, or equivalent).
• Strong communication and documentation skills to effectively collaborate with cross‑functional teams across engineering disciplines.
• Ability to adapt in a fast‑paced environment.
• Ability to obtain and maintain U.S. Government security clearance or ITAR compliance (U.S. Persons required).

Preferred Qualifications

• Hands‑on experience or academic background in testing for space systems and subsystems.
• Experience with script development or designing (e.g., Python or similar language or equivalent generation tools).

Benefits

• Paid holidays, sick time and unlimited vacation
• Excellent health and dental plans with 80% employer contribution
• 4% company matching 401(k) with immediate vesting
