Job summary

Rune Technologies in the United States is seeking a Backend Software Engineer focused on Maps & Routing to own the routing layer end-to-end within TyrOS. You will design, implement, and maintain the ground routing engine built on Valhalla, addressing multi-modal and time-dependent requirements for tactical edge operations.

You will work with engineers, product designers, and military stakeholders to ensure reliable, scalable routing capabilities, integrating weather, terrain, and road data

Qualifications

• 4–6 years of software engineering with focus on routing, navigation, or transportation systems.
• Hands-on experience building or extending a routing engine (Valhalla, OSRM, Graphhopper, or equivalent).
• Proficiency in C++ or Rust as a primary language; familiarity with Go is a plus.
• Comfort owning a technical layer – design, implement, debug, and iterate independently.
• Strong sense of ownership and a bias for action.

Responsibilities

• Own the design, development, and ongoing maintenance of Rune’s routing layer, built on Valhalla, as the sole engineer responsible for this system.
• Extend the existing routing foundation with new capabilities, including multi‑modal transport routing, time‑dependent cost modeling, and integration with operational data sources such as weather, terrain, and road availability.
• Collaborate with the broader platform team to expose routing functionality through clean APIs and integrate it into TyrOS workflows.
• Participate in technical design discussions and code reviews, contributing to a culture of engineering rigor and mission focus.
• Triage and debug routing issues in production, ensuring reliability and rapid iteration in support of operational needs.
• Work closely with engineers, product managers, and military stakeholders to ensure the routing layer meets real‑world sustainment requirements at the tactical edge.
