Backend Engineer

We’re a venture-backed startup with two years of runway and preparing to raise our Series A at a ~$100M valuation in the coming months. We’re building fast, shipping constantly, and looking for a backend engineer who can operate with founder-level intensity and ownership.

Role Overview

• You’ll architect and build the core systems that power intelligent, autonomous decision-making in dynamic, high-stakes environments. The work centers on distributed systems that must perform reliably under uncertainty — the backbone of our multi-agent simulation engine.
• If you have range across systems, data, infrastructure, or adjacent fields, that perspective is a superpower here. This is a role for someone who wants to build and evolve the core of the product, not just maintain it.

This role is onsite in Bellevue four days per week.

What You Bring

• 2–6 years of hands-on backend experience, ideally with C#/.NET Core, Linux, or Python
• Strong grasp of system design, distributed architectures, and scalable backend patterns
• Ability to own components end-to-end — from architecture to deployment
• High autonomy: you unblock yourself, move fast, and ship impactful code
• Comfort operating in high-pressure, high-ambiguity environments
• Alignment with the mission and problem space — we work with clients in the defense and DoD ecosystem, so comfort operating in that domain is important
• A builder’s mindset — you take pride in creating systems that are robust, elegant, and production-ready

Benefits & Compensation

• Excellent health, dental, and vision coverage
• Significant equity as a core part of the compensation package
• Opportunity to join early and meaningfully influence the architecture, infrastructure, and technical direction as the company scales into its Series A and beyond
