About Four Sea Group, Inc.

Four Sea Group is a 100% employee-owned technical mission support company based in Denver, Colorado. Founded by an aerospace industry veteran and PhD astrophysicist, we support complex defense, space, software, systems, and mission-focused programs for government and industry partners. What sets FSG apart is the caliber of our people and the way we operate: we are a reputation-driven team of highly skilled engineers and technical experts who are brought in for their depth, judgment, and ability to solve difficult problems. As an employee-owned company, we have built our compensation, benefits, and culture around a simple idea: when the company succeeds, that value should go back to the people doing the work.

About the role

We are seeking a Systems Integration & Test Engineer (SEIT) to support site hardware deployment, software integration, checkout, and verification activities for complex mission systems. This role is responsible for executing integration and test efforts through verification complete, troubleshooting system interaction issues, and supporting reliable delivery in a fast-paced engineering environment.

The ideal candidate brings strong integration and verification experience, practical system-level understanding, and the ability to work independently within assigned scope while coordinating effectively across software, hardware, and test teams.

What you'll do

Support site hardware deployment, integration, checkout, and test activities through verification complete.
Execute hardware/software integration and verification activities for complex mission systems.
Support verification of satellite ground software systems, including command and control and space vehicle mission management capabilities.
Develop, maintain, and execute automated test scripts to support integration and verification testing.
Analyze integration failures, diagnose software deficiencies, and support resolution through log analysis, debugging tools, and root-cause investigation.
Identify patterns across related technical issues and communicate findings clearly to developers and stakeholders.
Collaborate across engineering teams to resolve interaction problems and improve system behavior through integration and test feedback.
Support technical documentation, issue tracking, test results, and status reporting for assigned efforts.
Participate in agile execution environments and support continuous improvement in test, automation, and delivery practices.

Required Qualifications

Bachelor’s degree in Engineering, Computer Science, Systems Engineering, Aerospace Engineering, or another relevant technical field, or equivalent practical experience.
6+ years of relevant experience in systems integration, test, verification, or mission-focused engineering environments.
Active TS/SCI Security Clearance
Experience with site hardware deployment, integration, checkout, and test through verification complete.
Experience with satellite ground software system verification, including command and control and space vehicle mission management.
Experience with Python for scripting, automation, or test support.
Strong system architecture understanding, including the ability to comprehend how components interact and identify integration points.
Experience creating and maintaining automated test scripts used for verification testing.
Strong troubleshooting and diagnostic reasoning skills, including experience analyzing integration failures, using logs and debugging tools, tracing root cause, and identifying issue patterns.
Strong communication and collaboration skills, including the ability to clearly document issues and coordinate across development and engineering teams.
Ability to work independently on defined integration and test efforts in a complex technical environment.

Preferred Qualifications

Experience with Python automation frameworks, including BDD, Robot Framework, or similar tools.
Experience with Matlab, C, or C++ in integration, simulation, or verification environments.
Experience with MBSE concepts, models, or system artifacts that support integration and verification activities.
Experience with the Atlassian Suite, Bitbucket, or similar collaboration and configuration management environments.
Experience with Systems Tool Kit (STK).
Experience working in Agile program execution environments.
Experience with Docker, Kubernetes, or other containerized integration/test environments.
Experience supporting full CI/CD workflows, including GitLab.
Experience in space, satellite ground, mission management, or other mission-critical defense environments.

Salary: The salary range for this role is $120,500.00- $160,700.00 per year. The salary range provided is a good faith estimate representative of all experience levels. Four Sea Group, Inc. considers several factors when extending an offer, including but not limited to, the role, function and associated responsibilities, a candidate’s work experience, location, education/training, key skills, and market conditions.

Application Deadline: This position is expected to remain open through September 30, 2026. The company may adjust this deadline based on business needs and will update the posting as appropriate.

Benefits: FSG is 100% ESOP-owned, which means our employees share directly in the company’s growth. We offer competitive compensation, a strong employer-funded retirement plan, generous PTO and flexible time-off options, comprehensive health, dental, vision, life, short-term disability, and long-term disability benefits, plus a generous medical stipend that gives employees more choice and flexibility. Our model is intentionally built to keep more value with employees through salary, retirement, benefits, and ownership. You will work alongside experienced engineers and technical leaders on meaningful defense, space, software, systems, and mission support work, with room to grow as a technical expert, mentor, program contributor, or future leader.
