Responsibilities include modeling fluid systems, maintaining hydraulic actuator and control models, supporting launch and test campaign operations, and running Monte Carlo simulations. The role requires mathematical modeling, MATLAB/Simulink, Python data analysis, fluid-system control, flight software development in C/C++, and Git experience.

Design and develop composite and metallic primary and secondary structures for the Spectrum launch vehicle. Create CAD models, manufacturing drawings, integration drawings, and bills of materials. Provide technical guidance, review designs, manage development roadmaps, lead design reviews and trade studies, address production non-conformities, coordinate suppliers, define requirements and engineering changes, and mentor structural design engineers while collaborating across multidisciplinary aerospace teams.

Supports launch vehicle assembly, flight hardware integration, component and assembly testing, test setup, workflow improvements, cleanliness standards, and detailed technical documentation within the Launcher AIT team.

Owns fluid engineering modules for rocket propulsion test facilities and launch infrastructure across the full system lifecycle. Coordinates requirements, design, commissioning, procurement, delivery, risk management, and design reviews. Develops standardized engineering approaches, ensures regulatory and internal compliance, and applies fluid mechanics, thermodynamics, cryogenic systems, and pressure-gas expertise. Provides technical guidance to junior engineers and collaborates with propulsion, launch vehicle, and design teams.

Develop and maintain software testing systems for aerospace ground control systems. Responsibilities include creating test plans and automated tests, supporting CI/CD and DevOps workflows, extending SIL/HIL test setups, conducting integration, verification, validation, qualification, and regression testing, documenting results, analyzing failures, and collaborating with PLC and software engineers. The role requires RTOS testing experience, TwinCAT and Python expertise, test-rig experience, and familiarity with real-time automation systems.

Own the engine cycle and top-level technical architecture for a pump-fed liquid rocket engine. Build and validate cycle models, lead performance trade studies, size the engine, define requirements and interfaces, coordinate multidisciplinary development and testing, manage technical roadmaps, and guide propulsion design decisions through analysis and test evidence.

Own and evolve developer enablement platforms supporting secure, reliable software delivery across Ground Systems. Design scalable CI/CD pipelines, promote GitOps practices with ArgoCD and GitLab, automate infrastructure using IaC and scripting, and implement monitoring and SRE practices. Establish platform standards, documentation, and operational playbooks while mentoring engineering teams and leading communities of practice. The role also drives developer productivity, software quality, incident response, and adoption of internal platform capabilities.

Design, develop, and operate scalable data and backend systems for ingesting, processing, storing, and serving engineering and operational data. Build APIs, pipelines, data products, and ETL/ELT processes; contribute to data architecture, quality, governance, observability, and documentation. Collaborate cross-functionally and mentor less experienced engineers while working with streaming, time-series, analytical storage, cloud data platforms, and event-driven architectures.

Organize national and international transportation of goods and materials by coordinating carriers, brokers, freight forwarders, warehouses, and internal teams. Responsibilities include scheduling shipments, negotiating vendor contracts, managing transport documentation and invoices, tracking costs and service performance, maintaining compliance with customs, export controls, dangerous-goods, and industry requirements, and optimizing logistics processes to meet deadlines and budgets.

Leads the end-to-end supply chain for a space development program, integrating planning, purchasing, supplier management, and fast-make prototyping. Owns material and capacity planning, sourcing, supplier performance, risk mitigation, procurement spend, prototype manufacturing capability, KPIs, and transition from development into production. Partners closely with Engineering, Operations, and Programme Management to ensure build readiness and milestone delivery.

Support the full talent acquisition lifecycle through candidate sourcing, application screening, interview coordination, first interviews, job posting, ATS maintenance, recruiting analytics, KPI tracking, and recruiting events. The intern will also identify process improvements and assist with talent attraction projects while working onsite at least two days per week.

Leads compensation programs, salary benchmarking, offer reviews, annual salary cycles, bonus and commission plans, HR budgeting, workforce cost forecasting, and monthly reporting. Partners with HR, Finance, Talent Acquisition, and business leaders to improve compensation governance, automate processes, and support employee participation programs. The role requires strong analytical skills, advanced Excel, budgeting and forecasting experience, and stakeholder management in an international environment.

Leads indirect procurement and a small buyer team while managing selected categories hands-on. Responsibilities include category strategy, sourcing events, supplier evaluations, negotiations, contract awards, supplier performance, savings, process improvements, stakeholder engagement, procurement KPIs, governance, risk, and compliance across transport, facilities, professional services, tools, IT equipment, and related operational spend.

Advise senior leaders on people strategy, organizational design, talent planning, succession, DEI, employee relations, performance, and change management. Ensure compliant and scalable HR processes, collaborate with Works Councils and international teams, lead cross-functional initiatives, and use Workday for reporting and organizational updates. The role requires strong German and English skills, German HR expertise, international HRBP experience, and occasional travel.

Lead and develop the HR Business Partner team while advising senior leaders on organizational design, restructuring, workforce strategy, FTE planning, manager effectiveness, and leadership alignment. The role drives HRBP transformation across multiple countries, supports workforce budgeting, navigates country-specific labor considerations, and creates organizational clarity in a fast-changing aerospace environment.

The Senior Accountant will oversee accounting processes, ensure timely closings, prepare financial reports, optimize processes, and provide insights for cost control in Norway and Sweden.

Design and procure propulsion valves from prototype through serial production.
