Top Tech Jobs & Startup Jobs in Los Angeles, CA

Perform computational fluid dynamics analyses supporting the design and qualification of rocket combustion hardware, including injectors, thrust chambers, heat exchangers, and igniters. Review test and flight data to validate models, collaborate with hardware designers, and apply fluid mechanics and heat-transfer expertise to influence designs. Develop analysis methods that reduce iteration time using meshing, boundary conditions, pre/post-processing, and engineering scripting.

Manage inbound and outbound shipping, order fulfillment, freight coordination, export documentation, customs brokerage, and international shipments. Classify shipments using HTS codes and ECCNs, develop dangerous goods and trade compliance procedures, package shipments, operate forklifts, maintain shipping areas, and resolve questions with internal and external partners. The role requires physical material handling, inventory accuracy, and process improvement in a fast-paced aerospace manufacturing environment.

Partners with Engineering leaders to align people strategy with business priorities. Advises on organizational design, workforce planning, performance, change management, and employee relations; coaches leaders, supports high-performing teams, translates business insights into practical solutions, and communicates recommendations clearly. Requires 7+ years of progressive HR experience, including HR business partnering.

Owns end-to-end material planning for avionics hardware from development through production. Responsibilities include forecasting demand, analyzing BOMs and engineering changes, identifying long-lead risks, managing supplier material flow and shortages, allocating constrained components, supporting build readiness, and improving MRP and ERP planning accuracy. The role collaborates across engineering, sourcing, manufacturing, integration, testing, and launch teams.

Leads company-wide precision cleaning, contamination control, passivation, and special-process reliability for rocket hardware. Establishes process standards, qualification and validation frameworks, cleanliness criteria, inspection methods, technician certification, and governance. Scales clean-line capabilities from development through production, resolves complex contamination issues, leads root-cause investigations and corrective actions, and influences cross-functional engineering and manufacturing decisions while mentoring technical teams.

Develops, validates, and improves manufacturing test assets and processes for mechanical, electrical, and pneumatic rocket systems. Responsibilities include test equipment and tooling design, test sequencing, work orders, training, safety compliance, shop-floor support, test data analysis, root-cause investigations, and corrective actions. The engineer collaborates with design, manufacturing, production, supply chain, and quality teams to deliver scalable and reliable production testing.

Owns the design and evolution of scalable manufacturing and supply chain workflows, including MRP, procure-to-pay, material movement, factory automation, and change management. Builds technical infrastructure, integrations, and process-as-product solutions while improving data integrity, reliability, automation, and operational performance. Partners with manufacturing, supply chain, engineering, finance, and operations stakeholders to define requirements, implement changes, and establish governance, documentation, and technical standards.

Executes software testing and release tasks, writes Python automation for validation and artifact handling, supports release candidate publication and Run-for-Record campaigns, and assists with deployment validation, troubleshooting, CI/CD improvements, documentation, and data reviews under senior-engineer guidance.

Protect Relativity Space’s systems, people, and technical data by automating security operations, strengthening identity and access controls, implementing DLP, enabling secure development pipelines, and continuously enforcing CMMC and NIST controls. The role partners across IAM, cloud, AppSec, infrastructure, and GRC teams to investigate risks, remediate vulnerabilities, and improve security processes.

Owns forming operations for rocket primary structures, including roll forming and press brake process development. The role brings a large-sheet press brake work center online, creates work instructions and specifications, standardizes manufacturing processes, resolves shop-floor issues, provides design-for-manufacturing feedback, and leads process improvement projects. It requires engineering fundamentals in forming, metallic processing, mechanics of materials, inspection, GD&T, and aerospace manufacturing collaboration.
