Top Tech Jobs & Startup Jobs

Design, model, analyze, and test guidance, navigation, and control systems for launch vehicles. Perform trajectory and mission analyses, Monte Carlo simulations, HITL testing, flight code development, and customer-facing mission definition and proposal support.

Design, model, analyze, and test guidance, navigation, and control (GNC) for launch and mission formulation. Perform trajectory design and optimization, Monte Carlo and HITL testing, develop flight code and automation tools, support proposals and customer reviews, and collaborate across engineering and production for classified and commercial missions.

Design, build, and test fluid components (valves, actuators, regulators) for the Neutron launch vehicle. Create analytical models, CAD and drawings, lead design and test reviews, manage vendors, run prototype builds and qualification test campaigns, perform failure investigations and update designs to improve reliability, cost, mass, and build rate.

The Test Operations Engineer is responsible for the operation of test facilities supporting rocket engine tests, collaborating with engineering teams, ensuring safety and data quality, and resolving operational issues.

As a Senior Fluid Systems Engineer at Rocket Lab, you will lead fluid system design, provide guidance to team members, and coordinate with various engineering teams to ensure system functionality and performance.

Lead design, analysis, testing, and integration of stage fluid/plumbing systems between tanks and engines for the Neutron launch vehicle. Manage requirements, mentor peers, set standards, and collaborate across propulsion, structures, and operations to ensure reliable, reusable vehicle performance.

Perform trajectory design and analysis for launch vehicles and spacecraft, including orbital propagation, rendezvous, station-keeping, maneuver planning, collision avoidance, mission design support, simulation tool development, and real-time mission operations and anomaly response.

Support and enhance Rocket Labs LN ERP for global manufacturing and supply chain: provide application support, design and deploy ERP solutions, enable LN Cloud migration, maintain global business process standards, and partner with operations and engineering teams to improve ERP-driven manufacturing and supply chain performance.

Perform tracking, navigation, trajectory planning, maneuver design, and collision avoidance for Earth, lunar, and interplanetary missions. Develop and analyze ascent, orbit insertion, orbital maneuvers, rendezvous, and station-keeping; support mission design, launch windows, delta-V budgets, contingency planning, and real-time operations. Interface with flight software and GNC, produce trajectory data products, contribute to simulation tools, and support anomaly response and post-launch analysis.

Operate vehicle systems in Mission Control for test campaigns and launches; develop and maintain test plans, procedures, and HMIs; perform real-time troubleshooting and post‑test data analysis; integrate, test, and oversee mechanical, propulsion, and fluid systems; lead testing projects, mentor junior operators, and support Neutron and Electron vehicle operations readiness.
