Fortastra designs and delivers resilient, high-performance spacecraft that safeguard critical orbital assets and ensure freedom of action in space. We integrate advanced autonomy, sensing, and control into systems engineered for reliability, speed, and scale.
Our culture values simplicity, accountability, and disciplined execution. We expect leaders to think systemically, act decisively, and take ownership of mission outcomes. Aggressive innovation. Disciplined execution. Strength among the stars.
Our Engineering Team
You’ll join Fortastra’s Engineering Division. The mechanical engineering team is responsible for the physical realization of our spacecraft: structures, mechanisms, packaging, and integration that enable reliable, repeatable builds and rapid iteration across vehicles.
The Role
Fortastra is seeking a Sr. Mechanical Engineer focused on battery and solar integration to own the mechanical design, packaging, and integration of power subsystems on our spacecraft. You will be responsible for how batteries, solar arrays, and associated hardware are mechanically realized on the vehicle, including mounting, thermal and structural considerations, deployment interfaces, and harness routing.
This role is ideal for a mechanically strong engineer who wants to specialize in power-related hardware while still working across the full vehicle. You will collaborate closely with power electronics, avionics, thermal, and structures teams to ensure that power subsystems are robust, maintainable, and flight-ready.

Why Fortastra
We are a small, high-impact team building the next generation of autonomous orbital control systems for national security space. At Fortastra, leaders own outcomes from first principles through flight and directly shape the future of resilient, mission-critical spacecraft autonomy.
FORTASTRA TALENT & CULTURE PRINCIPLES
Values Driven by First Principles
We value engineers and operators who prioritize sound judgment, candor, technical rigor, bias for action, and intellectual honesty over corporate consensus. We care about the caliber of the system you build and the speed at which you solve problems.
Talent Density Over Headcount
A high-performing startup is built on dense talent, not organizational bloat. A single exceptional engineer designs, tests, and delivers faster than a bloated committee. We intentionally maintain a lean, elite engineering crew where every contributor directly moves the needle on the mission.
High Autonomy, High Ownership
We hire domain experts to execute, not to micromanage them. You own your systems end-to-end, from initial architecture and hardware design to testing and deployment. With absolute ownership comes the responsibility to deliver mission critical reliability.
Mission Context Over Bureaucracy
The best execution happens when teams are provided clear technical objectives, constraints, and operational context, rather than rigid top-down policies. We strip away red tape so builders can iterate, make decisions, and push hardware and flight software forward rapidly.
Disciplined Speed & Flight Rigor
We move fast because we test often and kill artificial bottlenecks, not because we cut corners. Rapid iteration on the test stand and in simulation is how we learn; an uncompromising flight-readiness bar is how we earn trust. Precision without friction, speed without recklessness.
Direct Impact, Not Career Bureaucracy
You don’t come to Fortastra to climb a corporate ladder or manage slide decks; you come to build complex, flight-ready systems from day one. Growth here is organic, driven by the magnitude of technical challenges you solve and the trust you build across the team.
Benefits
We take care of our employees so they can focus on what matters most: family, well-being, and life outside of work.
Unlimited Paid Time Off so that you have the time you need to rest and recharge.
Comprehensive Healthcare: Medical, dental, and vision coverage for you and your dependents, because peace of mind starts with feeling cared for.
Equity: Share in Fortastra's success with equity in the company you're helping build.
401(k): A 401(k) plan to help you invest in your future and plan for what's ahead.
Social Events: Regular social events, team outings, and company-sponsored activities that make this a place people are glad to be part of.
The pay range for this role is $130,000.00 - $170,000.00. Where an offer falls within that range depends on factors like your qualifications, experience, location, and interview performance, which we weigh against the market rate for the position.
Recruiters & Agencies: Fortastra does not accept unsolicited resumes or candidate submissions from recruiters, agencies, or third parties. Any candidate submitted without a signed agreement and prior written authorization from Fortastra will not be subject to any fee, and no relationship is implied. Please do not contact Fortastra employees, hiring managers, or recruiting team directly.
