The posting

ABOUT NUMERAL:

Numeral is transforming how taxes get done. Digital businesses are currently bogged down by a painful web of regulations across 47 states and 70+ countries. We’re eliminating this burden so teams can focus on their core mission.

We’re the largest and fastest-growing AI-native tax solution. Started in 2023, Numeral has raised over $57M from Benchmark, Mayfield, Y-Combinator, and many others. We now serve over 3,000 paying customers and have more than tripled our revenue every year in our history.

ABOUT THE ROLE:

We’re looking for a Foundational AI Engineer who thrives in ambiguity, enjoys building real-world AI systems end-to-end, and wants to define the technical and architectural foundations of an early-stage startup.

This is a hands-on role for someone who wants to design and implement LLM-powered automation systems: model orchestration, tool calling, MCP-style integrations, agentic workflows, and automation-driven tooling.

WHAT YOU’LL DO:

- Design, build, and operate production AI systems, including tool-calling agents, model orchestration layers, and RAG.

- Implement and maintain AI integrations using modern frameworks, MCP servers, and external model providers.

- Build and evolve scalable backend services and APIs that power automated workflows and customer-facing features.

- Think in automation and workflows: design systems using tools like n8n, Claude Code-style agents, or similar orchestration approaches.

- Make architectural decisions that balance latency, cost, reliability, and iteration speed.

- Own infrastructure, observability, and performance for both AI and non-AI services.

- Collaborate closely with product, design, and data teams to ship features that solve real customer problems.

- Help define engineering best practices, AI safety/reliability norms, and our overall technical culture.

WHAT YOU’LL BRING:

- 7+ years of experience building products in high-growth environments.

- 2+ years of experience building with LLMs.

- Avid use of state-of-the-art AI development tools such as Cursor and Claude Code.

- Fluency with backend technologies like PostgreSQL, Redis, and cloud services (AWS preferred).

- Experience with frontend development, especially TypeScript and its ecosystem.

- Strong product sense, balancing performance, flexibility, and speed.

- Comfortable working in dynamic startup environments with evolving needs.

- Excellent communication and collaboration skills.

- Startup mindset: Not scared of ambiguity and hungry for rapid growth

- Intensity & Ownership: This is not a 9-5 — we’re scaling rapidly and have a massive opportunity ahead of us.

- Customer Obsession: You deeply care about the user experience and solving their problems

NICE TO HAVES:

- Experience in payments, tax, accounting, or regulatory tech.

- Experience with automation tools (n8n, Zapier-style systems, workflow engines) or building internal automation platforms.

- Familiarity with MCPs, tool calls, agent frameworks, or model orchestration patterns.

- Understanding of vector databases and concepts (such as Pinecone, HNSW).

LOCATION:

- This role is hybrid (3 days a week in our NYC office)

WHAT WE OFFER:

- Competitive salary and equity - you'll share directly in the company's success

- Full medical, dental, and vision coverage

- Wellness perks like Headspace and the Peloton One App

- 401(k) to help you build long-term financial security

- Relocation assistance to NYC or SF (if needed)

- Lunch and snacks when you're in the office

- Regular team offsites and company events as we grow

- A culture built on ownership - your work matters and people will see it!

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
