Senior Backend Engineer (Integrations and Infrastructure)

OneTablet builds software used daily by restaurants to run their online ordering across Uber Eats, DoorDash, Grubhub, and more — reliably, at scale, without chaos.

We’re an early-stage product company with real customers, real traffic, and real production problems. We’re looking for a senior backend engineer who owns systems end-to-end, is comfortable with ambiguity, and likes building infrastructure and integrations that don’t break at 7pm on Friday.

What you’ll do

• Build and own deep third-party integrations (DoorDash, Grubhub, POS systems, delivery platforms)
• Design reliable backend systems: ingestion, sync, reconciliation, retries, monitoring
• Work on infrastructure & scalability (GCP, Pub/Sub, queues, background workers)
• Use AI in daily work: debugging, refactoring, automation, internal tools, agents
• Take ownership from design → production → incidents → improvements

What we expect

• Strong backend experience (Node.js / TypeScript)
• Experience with integrations, APIs, webhooks, async flows
• Startup / product environment experience (early-stage, small teams, fast iteration)
• Production mindset: logging, monitoring, edge cases, failure modes
• High autonomy: you don’t wait for specs, you clarify and move
• Comfort using AI tools as part of development (Cursor, Claude, etc.)

Nice to have

• Experience with payments, ordering, POS, or marketplace platforms
• GCP, Pub/Sub, BigQuery, PostgreSQL
• Interest in automation and AI-first workflows

How we work

• Small senior team, no micromanagement
• High trust, high ownership
• Direct communication, fast decisions
• You build it → you own it
