Every system we build is in service of a simple idea: space should be more accessible, responsive, and capable. Joining Portal means stepping into a team that believes in bold engineering, fast iteration, and the power of small groups to change what’s possible. If you want your work to directly shape the future of in-space mobility, join us. ### Position Summary Portal is seeking a Mission Engineer reporting to the Chief Product Officer. This is a multi-disciplinary role with an exciting opportunity to help shape a wide range of functions and systems at Portal spanning mission design, planning, and operations. Broadly, you will make orbital missions a success at Portal. Early focus will center on mission operations; however, the role will present opportunities for upstream work in mission and trajectory design, mission and vehicle performance studies, and external engagement with launch vehicle, regulatory, and customer stakeholders. ### Core Responsibilities ### Mission Operations - Plan and execute operations on console in Portal’s Mission Control Center - Develop protocols and train fellow engineers for console operations - Generate GUIs, procedures, alerts, and mission rules - Schedule ground passes, spacecraft tasks and maneuvers, and coordinate with external space traffic coordination groups - Develop automations to increase capability of a growing fleet while reducing burden on operators ### Mission Design - Develop Concept of Operations (CONOPS) for upcoming missions - Develop and execute 3DOF (degree of freedom) simulations to identify unique mission capabilities and solutions - Track vehicle performance and perform vehicle trade studies to achieve customer needs ### Mission Management - Identify and manage mission needs and customer requirements - Identify, plan, and close launch, regulatory, and customer deliverables - Coordinate internally with Program Management, Engineering, and Supply Chain to ensure mission success and on-time delivery - Plan detailed logistics for launch campaigns and support activities at the launch site …and other duties as assigned. We’re a startup – expect a wide range of learning & development & leadership opportunities. ### What You Bring to Portal This is a formative role in a startup engaged in real mission operations. Successful candidates demonstrate extreme ownership: they embrace ambiguity and broad responsibilities with an ability to distill concepts into disciplined operations with rigorous attention to detail. The ideal candidate will come with a deep functional knowledge in one or more spacecraft disciplines, and experience spanning design/analysis, development & test/launch/mission operations. ### Basic Qualifications The successful candidate will have: - Minimum 3 years of experience in launch vehicle or spacecraft development or operations - Bachelor’s degree in engineering - Experience in development engineering or similar activities that require ownership across several portions of the product lifecycle - Experience in test, launch, or mission operations, or other similar activities requiring real-time operations support ### Bonus Points - Experience obtaining regulatory approvals from FCC, ITU, NOAA, Range, etc. - Deep familiarity with SSCMAN 91-710, SMC-S-016, and/or SMC-S-025 - Direct familiarity with one or more space traffic coordination systems - Experience with 3DOF simulation tools such as STK, Copernicus, FreeFlyer - Demonstrated past ownership and successful delivery of complex systems - Willingness to obtain security clearance ### Work Expectations - Primarily onsite support with travel up to 25% time - Willingness to support in real-time mission operations with shifting on-call support Pay Range: $130,000 - $175,000 ### Compensation and Benefits Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience. --- Data: alder (https://alderhq.app).
