About OneTablet
OneTablet is a restaurant delivery management platform that helps restaurants sell more and operate better across DoorDash, Uber Eats, Grubhub, and other ordering platforms. We optimize the signals that platform algorithms use to rank restaurants, enhance menus with AI, and expand sales surface — so restaurants make more money, measurably, in dollars.

We operate AI-first. AI isn't a buzzword here — it's how we actually run. We use AI agents internally to monitor stores, investigate issues, and handle operational work that traditional teams do manually. Our support team is built around this: smaller, sharper, more technical, and every person has real ownership over outcomes — not just tickets.
 

What you'll do

- Build and own product features end-to-end (backend + frontend)
- Design and implement business logic and workflows used daily by restaurants
- Work with and extend autonomous agents, MCP servers, skills, hooks, and sub-agents as part of daily development
- Build automations across the software development lifecycle — not just AI-assisted coding, but autonomous systems that plan, execute, verify, and iterate
- Collaborate closely with product and design — not just "implement tickets"
- Proactively improve existing development practices and push the boundaries of what's automatable

What we expect

- AI-First Development (critical)
- 1+ year of hands-on AI-first development — AI is your default, not an add-on
- Proficiency with Claude Code, Cursor, or similar tools at a deep level — not tab completion, but agentic workflows, harness engineering, background agents
- Practical experience with MCP (Model Context Protocol) — building servers, designing tools, connecting agents to systems
- Experience creating and managing AI agents: skills, sub-agents, hooks, back-pressure mechanisms, context architecture
- Understanding of the full agentic engineering stack

Engineering
- Strong full-stack experience (Node.js / TypeScript + React)
- Hands-on experience with GraphQL in production
- UX sensitivity — you care how things feel, not just if they work

Product & Ownership
- Strong product vision — you think about what to build, not just how
- High ownership: you ship, you fix, you improve
- Ability to lead the full engineering process e2e — from discovery to production
- Startup / small team experience

Big plus

- Ability to improve existing development practices — introducing better workflows, tooling, automation patterns
- Desire to develop and grow AI development expertise within the team
- Experience with dashboards, admin tools, or B2B products
- GCP, PostgreSQL
- React Native

What you'll get

- Fast-growing, reliable tech startup with a long-term product and vision
- Work alongside experts in their domain who are passionate about AI-first development
- A team that genuinely burns for building with AI — not just talks about it
- Long-term project with real customers and real impact

How we work

- Small senior team, no micromanagement
- High trust, high ownership
- Fast decisions, short feedback loops
- You build it → you own it

If you do NOT want to disappear inside a large company doing small, invisible tasks for months – surrounded by people who don’t care, buried in bureaucracy, time tracking, and performance reviews that lead nowhere – this role may be for you.
 

If you DO want to work somewhere your contribution counts, where you can grow fast and work on real problems that actually matter – keep reading.
 

What the work actually looks like

• Design, deploy, and manage AI agents that automate real workflows
• Ship internal tools, external tools, and small applications end-to-end
• Solve practical engineering problems fast — integrations, scripts, automations, backend logic

We care more about how you think than what you’ve already shipped.

You’ll likely fit this role if:

• You use AI tools naturally as part of how you work
• You scope problems before writing code — and know what to skip
• You notice details others miss
• You’re honest about what you don’t know, and quick to figure it out
• You’ve built something recently, even if it was small

What we don’t care about

• Your years of experience
• Whether you’ve worked at a well-known company
• A perfect CV

Stack

We use what fits the problem. You should be comfortable with Python, basic deployment, and working directly with APIs and LLM-based tools.

Our hiring process

• Short assessment (~45 min)
• Interview with the founder
• If it clicks, we move fast

Short assessment

We use a testgorilla for our short assessment. No trick questions. No algorithm puzzles. Just practical scenarios that reflect what the job actually looks like.
