Job Description:

Title : Backend .Net developer

Location: Bellevue, WA (4 days onsite)

Job type (Fulltime/ Contract) : Fulltime

Stack: C#, .NET, AWS (Secret Environment), Docker, Kubernetes

Join a well-funded, high-caliber startup tackling some of the most complex technical challenges in the contested logistics and national security space. As a Backend Engineer, you'll help architect and build the core simulation engine powering intelligent, autonomous decision-making in dynamic, high-stakes environments.

You’ll work directly on distributed systems that must operate reliably under uncertainty, driving breakthrough performance using modern engineering practices and secure infrastructure. This isn’t a maintenance role—it’s for a builder who can own and evolve systems at the core of our product.

What You'll Do:

• Design and scale the backend for our multi-agent simulation platform
• Own distributed system components from architecture to deployment
• Collaborate with AI and frontend teams to power real-time decision loops
• Work in secure cloud environments to deliver production-grade systems

Ideal Candidate:

• 2–6 years of hands-on backend experience, preferably in C#/.NET
• Strong grasp of system design and distributed architectures
• Ownership mindset with a bias toward shipping impactful code
• Comfortable navigating high-performance, mission-driven teams

• This is more than just engineering—it’s a chance to protect lives, shape national security, and be part of a team that’s building what others only theorize.
