Job description

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!

E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service deliveryassociated with traditional satellite and terrestrial IoT systems.

We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.

TheMissionSystemsEngineer(MSE) is the single point of technical accountability forsystemsengineering on an assigned government contract or task order. The MSE owns thatmission's requirements baseline, interface control, verification and validation planning, and requirements compliance closure — reporting to the Program Manager and/or the ChiefSystemsEngineer(CSE), as assigned. The MSE operates within the enterprise system architecture and electrical ICD framework owned by the CSE, and is the CSE's forward-deployed counterpart on the contract: translating fleet-level architecture and standards intomission-specific requirements, schedules, and customer commitments.

Missionrequirements ownership — decomposing customer/contract requirements, allocating them to subsystem and payload budgets, and maintaining the requirements compliance matrix for the assignedmission.

Interface control — developing and baseliningmission-specific ICDs consistent with the enterprise electrical and system ICD framework; coordinating interface changes with subsystem owners and the CSE organization.

Verification & Validation — building and executing themissionV&V plan, defining and tracking Technical Performance Measures (TPMs), planning environmental test campaigns (TVAC, vibration/acoustic, EMI/EMC), and dispositioning test data and anomalies for the assignedmission.

Integration & Test support — supporting AI&T campaign planning and execution for themission, including FlatSat/Hardware in-the Loop activities, test readiness reviews, and anomaly investigation formission-specific hardware and interfaces.

Program and customer interface — serving as the technical point of contact to the government customer and Program Manager for the assigned contract; preparing for and presenting at contract technical reviews and milestones (e.g., SRR, PDR, CDR, TRR) and closing associated action items.

Configuration management — maintaining themission's configuration baseline, participating in the Configuration Control Board process, and managingengineering change orders affecting the assigned contract.

Digital thread / MBSE — maintainingmission-level traceability between requirements, design artifacts, verification evidence, and as-built records within the enterprise digital thread; working familiarity with MBSE tools (DOORS NG, Cameo, SysML).

Contract deliverables — supporting preparation of contract data requirements list (CDRL) items and other government deliverables related tosystemsengineering.

8+ years of progressivesystemsengineering experience in the space or defense industry, including direct requirements, ICD, or verification ownership on at least one program from early design review through delivery or on-orbit operations.

Government contract experience — prior work on a U.S. government space, satellite, or space-adjacent program, with familiarity navigating customer technical reviews, CDRLs, and government-furnished requirements.

ICD and design review experience — direct responsibility for requirements traceability and verification closure; has presented technical status or baselines at formal design reviews before a customer or internal review board.

Prior subsystem ormissiondepth — hands-on experience in a subsystem (payload, bus, ground, RF/comms) ormissionengineering role prior to or alongsidesystemsengineering responsibilities, sufficient to credibly coordinate across disciplines.

Digital communications familiarity — working knowledge of RF link design, phased arraysystems, modem/waveform, or OSI Layer 1–2 protocol architecture is a plus.

Independent judgment under oversight — ability to make and defendmission-level technical decisions and risk trade-offs, escalating to the CSE or Program Manager where enterprise-level authority is required.

Security clearance — active Secret or Top Secret clearance, or the ability to obtain one, as required by the assigned government contract.

This is a full time, exempt position, based out of our Saratoga office. The target base pay for this position is $100,000 - $200,000 annually. The total compensation packaged will be determined by various factors such as your relevant job-related knowledge, skills, and experience.

We are redefining how satellites are designed, manufactured and used—so we’re looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in-orbit activities. If that’s your experience – then we’ll be immediately wow-ed.

E-Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role.

Why E-Space is right for you:

As a member of our team, you will play a crucial role in driving our success. Our team members have a strong sense of dedication and responsibility; this includes a strong commitment to our mission to create an entirely new suite of global capabilities to improve lives, business efficiencies and build a smarter planet. This means that there will be times when extra hours, including nights and weekends, may be needed to meet critical deadlines and mission goals. In return, we offer a dynamic work environment with opportunities for professional growth and development and the chance to make a meaningful impact in a high-growth industry.

We want you to make the most of your journey at E-Space. That’s why we support and invest in the physical, emotional and financial well-being of our team members and their families.
