Job summary

E-Space is actively seeking a Mission Systems Engineer to own mission requirements, manage interface definitions, and drive verification and validation across a multi-discipline team. The role reports to the CSE/Program Manager for a government contract and requires deep MBSE experience and system-level thinking.

With 8+ years in space or defense, you will coordinate across payload, bus, RF/comms, and ground segments, ensuring traceability and compliance with design baselines and ICDs.

Qualifications

• 8+ years of progressive systems engineering experience in space or defense, including requirements ownership, ICDs, or verification on at least one program.
• Experience navigating government contract reviews, CDRLs, and government-furnished requirements.
• Direct responsibility for requirements traceability and verification closure; capable of presenting status at formal reviews.
• Hands-on experience in a subsystem or mission engineering role to coordinate across disciplines.

Responsibilities

• Mission requirements ownership: decompose customer requirements and allocate to subsystems and budgets.
• Interface control: baseline mission ICDs and coordinate changes with subsystem owners and CSE.
• Verification & Validation: develop and execute V&V plans, define TPMs, plan environmental tests, disposition data.
• Integration & Test support: plan and execute AI&T campaigns, including FlatSat and HWIL activities.
• Program interface: act as technical point of contact to government customer and PM, prepare reviews and close actions.
• Configuration management: maintain mission configuration baseline and manage engineering change orders.
• Digital MBSE: ensure traceability between requirements, design artifacts, verification evidence, and as-built records.
• Contract deliverables: assist in preparing CDRLs and other government deliverables.

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.

What you will do:

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.

What you bring to this role:

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.
