Backend Engineer

Walt is an agentic data platform that runs in real enterprise environments. That means high-throughput APIs, long-running agent workflows, secure data access, reliable orchestration, and cloud infrastructure that doesn't fall apart under load.

We're an early team with high trust and low ego, working on deep technical problems across AI, data, and distributed systems. We value directness, intellectual honesty, and people who care about building great systems.

Why This Role Exists

Cloud / Backend Engineers build the backbone of Walt.

This role is about building durable systems: the services, workflows, and infrastructure that allow AI and data agents to operate safely, reliably, and at scale. You'll design core backend services, cloud deployments, and execution frameworks that everything else depends on.

If you enjoy system design, distributed services, and making complex systems boringly reliable, this role is for you.

What You'll Do

Build core backend services

• Design and implement APIs that power Walt's agent execution and data access
• Build services for job orchestration, task execution, and state management
• Handle long-running workflows, retries, and failure recovery

Design scalable system architecture

• Design service boundaries, data flows, and contracts
• Make thoughtful tradeoffs between simplicity, performance, and extensibility
• Ensure systems scale with customer usage and data volume

Own cloud infrastructure

• Design and operate cloud deployments (AWS / GCP / Azure)
• Build secure, production-grade environments for enterprise customers
• Manage networking, IAM, secrets, and environment isolation

Enable reliability and observability

• Implement logging, metrics, and tracing across services
• Design health checks, alerts, and monitoring
• Make failures debuggable, not mysterious

What We're Looking For

• Strong software engineering fundamentals
• 4+ years building production backend systems
• Strong Python (or similar backend language)
• Deep understanding of APIs, services, and distributed systems

System design experience

• Comfortable designing systems from first principles
• Experience with queues, workers, schedulers, and async processing; database and optimization
• Understands tradeoffs around consistency, latency, and reliability

Cloud and infrastructure knowledge

• Hands-on with AWS, GCP, or Azure
• Experience with containers (Docker) and orchestration (Kubernetes preferred)
• Familiar with CI/CD, infrastructure-as-code, and deployment pipelines

Operational mindset

• You think about failure modes, not just happy paths
• You design systems that can be monitored, debugged, and evolved
• You care about performance, cost, and security

High ownership

• Comfortable owning services end-to-end
• Will dive into unfamiliar parts of the system to fix real problems
• Bias toward action and clarity

What Makes This Role Different

• You're building the platform that AI systems depend on, not just CRUD APIs
• Reliability and correctness matter as much as speed
• You'll influence architecture decisions early, before things calcify
• Your work directly impacts every customer deployment

Why Walt

• Real customers, real data, real scale
• Early team with high trust and low ego
• Deep technical problems across AI, data, and distributed systems
• We value directness, intellectual honesty, and people who care about building great systems
