Senior Full Stack Engineer, Wordware

• You have 5+ years of engineering experience building and operating backend systems in production. You've been on-call
• You're fluent in TypeScript and comfortable working across the stack, but your instinct is to go deeper on the backend
• You've built real-time systems: WebSockets, SSE, event streaming, or message queues in production
• You have distributed systems intuition, you understand consistency tradeoffs and have opinions about them
• You've shipped infrastructure to real users, not just internal tooling

Desirable

• You’ll write and ship full-stack features end to end, from the agent runtime and backend APIs, to the web and desktop UI that users interact with every day
• We're still ~15 people and shipping to our first paying users. You won't just be building features, you'll be making the decisions that determine whether this system holds at 1000x the current load
• You'll work directly with our CTO. Here are a few examples of the kinds of things you might work on:
• Build and operate the sandbox infrastructure where agents execute code, process isolation, resource limits, secure credential handling across thousands of concurrent sessions
• Design the deployment and migration pipeline for a Cloudflare Workers + Fly.io architecture, including blue-green rollouts and canary patterns
• Instrument real-time workloads end to end: SSE streaming, task queues, and multi-model LLM provider routing
• Ship new backend capabilities, tool integrations, scheduled task execution, memory indexing, and see them used by real people the same week
• Reduce operational toil for a small team: structured logging, tracing, monitoring, and incident response tooling that actually works at our scale
• Stack:
• TypeScript, Cloudflare Workers, Durable Objects, Hono, Driz

• We keep our process simple. Exceptional candidates go from first touch to offer within 2 weeks
• Application: Submit your resume and answer a few short questions
• 15-minute intro call: Quick check to align on location, motivation, and logistics. If it's a go, we move fast from here
• 45-minute technical interview: You'll work through a real backend problem. We're looking for fluency, depth, and how you think about systems
• System design interview: A deep dive into how you architect systems. We'll walk through a real Wordware problem together
• Final conversation: We answer your questions and scope out the work trial
• Work trial: Paid trial to work on a real project in person with us, usually a few days to two weeks (flexible to do what works for you). See how we work and whether this feels like the right fit on both sides
