Opaxa | Founding Full-Stack Engineer | San Francisco | Full-time | $200K–$300K + founding equity | opaxa.ai

Opaxa is the AI agent platform that runs restaurant back-office operations. Not another dashboard — agents that take the work off the operator's plate and act: build the schedule and push it to action, place the order with distributors, audit the invoice for overcharges, draft the review reply. The operator approves what matters; the rest gets done.

The unfair part: the founder owns and runs a 40-location restaurant company with over 750 employee's — so Opaxa's first customer is a real, operating restaurant group with real data and real stakes from day one. Deep domain expertise is built in, and your work runs in real restaurants immediately, not after a six-month hunt for a design partner. Well-funded.

A working prototype is already built. Now I'm hiring a founding full-stack engineer to take it from prototype to production: own the architecture, the agent runtime, the backend, and the integrations the agents act through (Toast, Paycom, Sysco, and more), set the technical bar, and grow the team behind you.

You'd work directly with me — I own product, customers, and the domain; you own the AI and the build. We'd be hiring additional engineers and account managers within the first year.

You're a fit if you: - have shipped agentic systems to production — plan-and-act, not chatbots or wrappers - are a strong full-stack builder (Python and/or Node, Postgres, real infra) - use the latest AI tooling (Claude Code / Cursor) as your default want to own a whole product as the first engineer, and eventually lead

Stack: React/TypeScript, Python/Node, Postgres, the Anthropic API, integrations across the restaurant stack.

To apply: email me at colton@opaxa.ai with the most impressive agentic system you've personally shipped — what it did, what you owned, and what made it hard — plus your resume or links. I read every one and reply. Please write it yourself; if it's clearly AI-generated, I'll pass.

Snowflake | Forward Deployed Engineer | Menlo Park, CA | ONSITE

I’m part of Snowflake’s Applied AI / Forward Deployed Engineering team, and we’re hiring for two roles: Forward Deployed Engineer and Senior Forward Deployed Engineer.

We work directly with strategic customers to design, build, deploy, and improve production AI systems on Snowflake. That includes LLM applications, RAG and agentic workflows, evaluation frameworks, guardrails, observability, and production iteration using Snowpark, Cortex, and Snowflake’s native AI capabilities.

For the FDE role, we’re looking for strong engineers who can build and ship customer-facing AI systems end to end, especially if you’ve worked on LLM apps and care deeply about evals and quality. For the Senior role, we’re looking for someone who can lead multi-engineer AI engagements, mentor other engineers, and still be hands-on in architecture and implementation.

Both roles are customer-facing and involve travel, including at least 25% onsite time with strategic customers.

If you like working in ambiguity, building real AI systems instead of demos, and partnering closely with customers to get things into production, these roles are a good fit.

z0.ai | Full Time | Founding Engineer | On Site 5 days a week | NYC | $140-$180k USD + equity

We're helping non technical users adopt AI by making usage visible. Power users become role models and people can upskill to gain value rather than lose their jobs to AI.

It's a complex problem because we need to balance trivial UX, with a slew of security and compliance requirements.

This is the first non founder developer role on the z0.ai codebase. We need someone who can own the full stack end to end: product surfaces people enjoy using, services that stay correct, and the taste to make both feel like one product.

We're funded and are live with our first customer already. We expect to onboard our next customer later this week and are actively ramping up sales efforts.

Check out the full job posting at https://www.z0.ai/careers/founding-engineer/ and send an email to join@z0.ai

Paymail | Engineer | REMOTE | Startup Equity Only

Paymail is an invoicing and money transferring service over email. Because it's alot easier to send $50 to email@example.org than to send it to a long series of digits representing a branch and account number. In a way Paymail is an internet native payments competitor to x402.org. I'm the founder and I'm on a mission to make every bank your email provider. I spent the last year working for a banking outsourcing company and it gave me some good insights into what's possible in the FinTech world. I'm currently searching for a React+Typescript developer with good design instincts to give a huge chunk of equity to and become a cofounder of the company working with a well written medium sized React+Typescript codebase that represents our product.

Startups are busy but to get the product to an MVP stage is not very far away at all so it would suit someone looking for a potentially profitable side hustle or on a full time basis as well.

TypeSafe AI (https://typesafe.ai/) is a well-funded stealth mode company making a new class of AI models which enable a reliable way to embed composable intelligence into traditional software, founded by a co-author of ChatGPT/RLHF/GPT4 (answering the questions "If AI is so smart, why are we barely automating any work? Why does today's AI always need a human-in-the-loop?").

We're especially looking for people to join our Synthetic Data research team - no previous data experience needed (synthetic or otherwise). We need strong engineers who care deeply about the end use cases and whose instincts are to NOT trust LLMs blindly and look at the reality of their generations (much more investigator in the spectrum of investigator vs optimizer).
