The role carries two mandates: acting as GalaxEye's technical authority over a turnkey ADCS procured from an external vendor, and building our internal ADCS design and analysis capability in parallel. You must be able to independently reproduce and challenge the vendor's analysis rather than manage it at arm's length.\nResponsibilities\nOwn ADCS requirements, pointing budgets - accuracy, knowledge, stability, jitter, agility, settling - and their flow-down from mission needs\nOwn the ADCS SRD and the ADCS-to-bus ICD\nRun vendor technical evaluation and selection; review and independently verify vendor design data packs, analysis and simulation results\nDefine and agree the acceptance test campaign; witness and accept vendor testing\nOwn sensor and actuator accommodation - mounting, alignment, FOV, thermal, magnetic cleanliness, EMC\nBuild and own GalaxEye's internal closed-loop 6-DOF ADCS simulation, including flexible body dynamics and environmental disturbances\nDesign attitude determination and control: sensor fusion and estimation, control laws, mode design and transition logic, FDIR and safe mode\nSize actuators and define momentum management strategy\nRun Monte Carlo campaigns for performance and robustness verification\nProvide mass properties, MOI, CG and alignment constraints to the mechanical team; ADCS processing and telemetry requirements to C&DH\nInterface with the Missions team on manoeuvres and attitude control during burns\nOwn GNC content at MCR, PDR, DDR, CDR and FRR; own on-orbit commissioning and ADCS performance characterisation\nRequirements\n7+ years in spacecraft GNC/ADCS\nHas taken at least one ADCS through to flight and on-orbit operation\nDeep attitude dynamics and control fundamentals - able to derive, not only apply\nHas built closed-loop ADCS simulations in MATLAB/Simulink, Python or equivalent\nAttitude estimation - Kalman filtering, sensor fusion, star tracker and gyro integration\nPointing budget derivation and allocation across error sources\nActuator sizing and momentum management\nHas specified or accepted an ADCS or comparable subsystem from an external supplier\nDesirable\nEarth observation mission GNC - agile, slew-intensive tasking\nSmallsat ADCS in the 100-500 kg class\nFlexible body dynamics and jitter analysis\nHardware- or processor-in-the-loop test setup\nFlight software interface - algorithm handover and V&V\nOrbit determination and GNSS processing\nOn-orbit commissioning and anomaly resolution\nFamiliarity with the ADCS supplier landscape\nQualifications\nDegree in Aerospace Engineering, Control Systems or a closely related discipline; postgraduate qualification preferred\nBenefits\nWhat We Offer\nFair Compensation in line with current market standards.\nStart-up Culture: Be part of a high-growth, innovation-driven team.\nOpen Culture: Freedom to explore, propose, and implement new ideas and processes.\nLeadership Exposure: Opportunity to work directly with the Founding Team at GalaxEye.\nIndustry Mentorship: Work with advisors and mentors holding senior positions and decades of industry experience.","description_format":"text","description_chars":3136,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Satellite Manufacturing","Earth Observation"],"lifecycle":[{"event":"open","at":"2026-10-21T10:40:16Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":27,"reasons":["conf:2","velocity","win:early"],"computed_at":"2026-10-23T05:54:15Z"},"pay":null,"html_url":"https://alion.io/job/galaxeye-space-gnc-lead","json_url":"https://alion.io/job/galaxeye-space-gnc-lead.json","meta":{"generated_at":"2026-10-24T00:48:39Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":1230,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":59381},"rest":"https://alion.io/mcp/rest/get_company?id=59381"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fgalaxeye-space-gnc-lead"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fgalaxeye-space-gnc-lead"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fgalaxeye-space-gnc-lead"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/galaxeye-space-gnc-lead\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgalaxeye-space-gnc-lead"}]}
