What they're building

Arc avionics and flight electronics strong signal

Today: Arc, which the company site calls an autonomous, reusable, low-cost space-based delivery vehicle; postings add hypersonic testing and national security missions

Roles: Senior Avionics Mechanical Engineer · Senior Electrical Engineer · Staff Avionics Engineer · Senior Avionics Engineer · Senior RF Systems Engineer · Electrical Test and Assembly Technician II · Senior Antenna Engineer · RF Test Engineer II · Senior Harness Engineer · Senior Avionics Test and Integration Engineer · Senior Test Engineer (Avionics) · Senior Embedded Software Engineer (Avionics) · Avionics Harness Engineer II · Avionics Embedded Software Engineer II

Requirements mention: mixed-signal · fault-tolerant and failover-capable electronics design · radiation-hardened or rad-tolerant system design · RF link budgets · IRIG-106 · environmental qualification

Inference: avionics is hiring across electrical, RF, antenna, harness and embedded software roles at once, which suggests Arc's flight electronics and telemetry are designed and qualified in-house.

Arc flight, autonomy and ground software strong signal

Today: Arc, which the company site calls an autonomous, reusable, low-cost space-based delivery vehicle

Roles: Senior Flight Software Engineer, Arc Vehicle · Staff Flight Software Engineer, Arc Vehicle · Autonomy Engineer I, Arc Vehicle · Engineering Manager, Arc Vehicle Software · Ground Software Engineer II, Arc Vehicle · Senior Flight Software Engineer · Senior Ground Software Engineer

Requirements mention: real-time flight software · fault detection, isolation, and recovery (FDIR) · Software-in-the-Loop (SIL) · Hardware-in-the-Loop (HIL) · safety-critical state machines

Inference: flight, autonomy and ground command-and-control software are all being hired for Arc, which suggests the company builds both the onboard and ground control software in-house and tests it on SIL/HIL benches.

Arc thermal protection, structures and in-house TPS/composite production strong signal

Today: Arc, a reentry vehicle (site heading: 'Advanced Reentry')

Roles: Engineering Manager, Arc Vehicle Mechanical · Senior Thermal Structures Engineer · Principal TPS Materials Engineer · Senior TPS Design Engineer · Senior TPS Technician · TPS Technician I · Senior Chemical Process Engineer · Senior Tooling Engineer · Senior Mechatronics Engineer · Senior Manufacturing Engineer · Staff Mechanisms Engineer · Structures Engineer II

Requirements mention: ablative TPS materials · carbon phenolic ablators · sol-gel infusion · scale-up · automated fiber placement (AFP) · composite manufacturing automation · Layup molds · thermal protection system (TPS) integration

Inference: alongside TPS design, Reentry is hiring for chemical process scale-up, tooling and robotic fiber placement, which suggests heat shield and composite parts are being produced in-house, not only designed.

Arc aerothermal and aerodynamic analysis moderate signal

Today: Arc, a reentry vehicle (site heading: 'Advanced Reentry')

Roles: Senior Aerothermal Engineer · Senior Aerodynamics Engineer · Staff Aerothermal CFD Methods Engineer · Staff Aerothermal CFD Engineer · Senior Propulsion and Energetics Thermofluids Engineer

Requirements mention: high-enthalpy CFD · aerothermal database · hypersonic aerodynamics · wind tunnel or arc-jet test campaigns · plasma wind tunnel

Inference: aerothermal, CFD methods and plasma wind tunnel roles together suggest the company is building its own hypersonic heating models and test capability.

Arc guidance, navigation, control and accurate landing moderate signal

Today: Arc, which the company site calls an autonomous space-based delivery vehicle

Roles: Staff GNC Engineer (Guidance) · Staff GNC Engineer (State Estimation) · Senior GNC Engineer · Staff Mission Design Engineer · Parachute Systems Engineer II · Test Engineer II

Requirements mention: trajectory optimization · real-time onboard optimization solvers · Kalman filtering · Joint precision airdrop system (JPADS) design and testing · aerial drop test campaigns

Inference: GNC hiring in both Reentry and Accurate Landing, plus parachute and drop-test roles, suggests work on guiding Arc through reentry and down to a precise landing point.

Defense hypersonic test business development moderate signal

Today: Postings describe Arc as serving hypersonic testing and national security missions; the site does not mention these

Roles: Director of Business Development, Test and Targets · Government Relations Executive

Requirements mention: procuring hypersonic flight tests · early capture activities · defense authorization and appropriations · Department of Defense

Inference: a test-and-targets business development lead and a D.C. government relations hire suggest the company is pursuing Department of Defense hypersonic test work for Arc.
