About KSAT Hyper

Hyper is a strategic initiative by Kongsberg Satellite Services (KSAT) to redefine how space data is delivered, secured, and used. By extending the world's most trusted ground station network into low Earth orbit, Hyper is building a new layer of space infrastructure designed for speed, resilience, and sovereignty.

At its core, Hyper enables near-real-time access to space data anywhere on Earth. By combining an orbiting relay capability with KSAT's global ground network, Hyper drastically reduces latency between satellite tasking, data acquisition, and decision-making. This capability is increasingly critical for applications where timing, trust, and availability matter --- including Earth observation, climate monitoring, security, defense, and commercial operations.

Hyper is not a single mission or a one-off system. It is a long-term infrastructure program designed to scale over time, support multiple customers and mission types, and integrate tightly with existing and future space systems. The first Hyper satellites are scheduled for launch in 2027, marking the transition from development to operations, and the starting point for a broader constellation and service evolution in the years that follow.

Joining Hyper means contributing to the early build-out of a strategically important space capability, working at the intersection of space systems, communications, and operations. The work is foundational, technically demanding, and mission-critical; it directly shapes how satellite services will be delivered at scale in the next decade.

About Replica

Replica is our mission analysis and orchestration platform used to model and operate complex space networking scenarios. The team builds high-fidelity simulations, planning tools, and backend services that turn domain models into operationally useful outputs.

What you will do

• Design and implement simulation and modeling services that power planning and analysis workflows.

• Build robust backend components in Rust and/or Python, with an emphasis on correctness, performance, and maintainability.

• Develop domain models and compute pipelines for scenario evaluation (e.g., contact plans, network constraints, capacity envelopes).

• Collaborate closely with product, mission analysis, and other engineering teams to translate operational questions into software.

• Contribute to automated testing, CI/CD, observability, and engineering standards across the backend stack.

What we are looking for

• Professional experience developing backend applications in Rust and/or Python.

• Master's degree in a relevant field (computer science, engineering, physics, applied math, etc.); equivalent experience may compensate for a degree.

• Experience from game development (e.g., simulation loops, determinism, performance optimization) and/or scientific computing (e.g., numerical methods, modeling, data pipelines).

• Strong software engineering fundamentals: testing, code review, debugging, and performance profiling.

• A collaborative, pragmatic team player who communicates clearly and enjoys working cross-functionally.

Nice to have

• Experience building simulation frameworks or large-scale scenario evaluators.

• Familiarity with numerical computing, optimization, or discrete-event simulation.

• Experience with event-driven architectures, asynchronous Rust, or high-performance Python patterns.

• Interest in space systems, mission operations, or networking (not required).
