Infrastructure Engineer (DevOps)
WeMachines brings chat, tasks, docs and calls together for start-ups and their AI teammates. It runs on Cloudflare Workers and Durable Objects, Supabase Postgres, AI models from several providers and a desktop app we ship ourselves. Today the engineers who build features also run all of that. You’d be our first dedicated infrastructure engineer, responsible for reliability, security and cost.
On a B2B contract. Equity package included.
What you’d actually do
- Own the production setup: Cloudflare Workers, Durable Objects, Supabase, storage, DNS and secrets.
- Make deploys boring. CI, database migrations, preview environments, desktop and mobile release pipelines.
- Set up monitoring and alerts that tell us something broke before a customer does, and be the one who fixes it.
- Keep the AI side reliable - model providers go down, rate-limit and change prices, and the product should barely notice.
- Watch the cloud and AI bill, and cut it without making anything slower.
- Help with security and compliance work as bigger customers ask for it.
Who this fits
- You’ve run production systems that real people depended on, and been on call for them.
- You know Postgres well - migrations, performance, backups, access rules.
- You write infrastructure as code and automate what you do twice.
- You’re comfortable reading and fixing application code, not only the layer under it.
- You use AI tools in your own work and want to push that further.
Bonus points
- You’ve worked with Cloudflare Workers, Durable Objects or Containers.
- You’ve been through SOC 2 or a similar audit.
- You’ve shipped signed desktop apps and know what notarisation is.
