We are building a high-fidelity software platform for space. The system spans a high-performance physics simulation engine, a scientific data pipeline, a REST and event-streaming backend, and a native desktop client with 3D rendering.

This is not an architecture-only role. The Principal Software Engineer is the final technical authority and is expected to be hands-on across all layers — writing simulation code, designing data interfaces, making HPC infrastructure decisions, and being the person who can sit down, open an editor, and solve the hard problem anywhere in the system.

You will own the architecture, make and document the decisions that stick, and be directly accountable for correct implementation across the team.

What You Will Actually Do

Own the end-to-end software architecture and be the final arbiter of all design decisions across every layer
Write and review production-quality numerical simulation code in a compiled systems language




Design and implement the data access layer that sits between HPC job output and the application backend — handling large binary scientific datasets, incremental writes, and on-the-fly computation at query time
Define and enforce interface contracts between the simulation core, the data layer, the API backend, and the desktop client
Design the HPC job lifecycle — submission, monitoring, interactive and batch execution modes, command channels, and event streaming to connected clients
Build and maintain the application backend including real-time event fan-out, role-based access control, and report generation
Make technology selection decisions with explicit written rationale that survives team turnover
Write detailed design documents that junior engineers implement from — unambiguous, complete, and correct
Mentor engineers across the stack; conduct reviews with the depth of someone who wrote the code themselves

Requirements
