Software Engineer (Backend-Focused)

What you will do

• You will work on software projects in client engagements, and over time, internal platform capabilities. You will:
• Build and maintain backend services for our LLM gateway — routing, rate limiting, key management, and observability in front of the inference fleet.
• Contribute to sandboxing and isolation infrastructure that keeps agent-generated code safe to execute, working alongside our security-focused engineers.
• Support Kubernetes-based platform services, including operators and autoscaling logic adjacent to our inference platform.
• Write high-performance backend code in Go, Rust, or async Python (FastAPI/Starlette), working with infrastructure like Envoy and gRPC.
• Instrument services with OpenTelemetry so behavior, latency, and cost stay observable as the platform scales.
• Collaborate across the gateway, sandbox, and inference platform teams, flexing across areas as priorities shift.

Core Qualifications - Technical and foundational

• 4+ years of experience in backend engineering fundamentals: distributed systems, API design, and production experience in Go, Rust, or async Python.
• Familiarity with LLM-specific backend concerns (rate limiting, caching, token accounting) is a plus, though not required on day one.
• Exposure to Kubernetes and containerization; interest in sandboxing or security is a plus.
• Comfort working across a range of platform concerns rather than one narrow specialty — this role is intentionally broader than our specialist infra profiles.
• Eagerness to grow into deeper specialization in gateway, sandbox, or inference infrastructure over time.

Values and Culture Qualifications

• High emotional intelligence and a learning mindset
• Strong collaboration skills
• Enjoy others' success and a fun, positive environment.
• Comfortable making decisions in the face of ambiguity and course correcting as needed.

Bonus Qualifications (not required but a huge plus)

• Experience in both startup and enterprise environments
• Past work in energy, real estate, utilities, climate or related fields
