## Job description

## About the Role

As a Senior Product Engineer on our Product Engineering team, you'll own features from idea to production — and stay accountable for whether they actually work for users. Depending on where the biggest challenges are, you could be working across our Core ai, Apps, Marketplace, or Integrations.

This isn't a role where someone hands you a ticket. On Monday you might prototype a new conversation-to-application flow with a designer. By Wednesday you're debugging a tricky inference issue. By Friday it's live and you're watching how users respond. The cycle is short because the team is small and the surface area per person is large.

## What You'll Actually Do

- Take product problems end-to-end — from data model to deployed interface — without waiting for someone to scope a lane for you
- Prototype fast, ship often, and instrument everything so you know what's working before anyone asks
- Push back when something doesn't feel right — UX, architecture, scope — and bring an alternative, not just the objection
- Use AI aggressively to move through unfamiliar territory — we build AI tools, and we expect you to use them to build faster than any one person should be able to
- Work directly with product and design to shape what gets built, not just how

You Might Be a Great Fit If…

- You've shipped products where you owned the product decisions, not just the technical ones — and you can point to something real that users loved
- You instinctively reach for AI when facing an unfamiliar part of the stack — not because you can't learn it, but because you know the faster path to a working solution
- You care as much about how software feels as how it's built — a clunky interaction bothers you the same way a bad abstraction does
- Ambiguity doesn't stall you — you create enough structure to move, then stop structuring and ship
- You close loops without being prompted — options, not problems
- You're energised by small teams where your work reaches real users within days, not quarters

Practicalities

- Location: Zürich, Switzerland — full-time on-site. We don't offer remote or hybrid arrangements.
- Stack: TypeScript across the stack — React, Node.js, SQL/NoSQL. Familiarity matters more than years.

## About Caffeine.ai

## Company Overview
- **One-liner**: Caffeine.ai is an AI-powered development platform that lets users create and update full-stack applications through natural language chat, built on a self-writing open tech stack.
- **Entity Type**: Private (funding stage not publicly disclosed)
- **Headquarters**: Redwood City, California, USA (with a second office in Los Angeles and a significant engineering hub in Zurich, Switzerland)
- **Founded**: Year not publicly disclosed (emerged as part of the DFINITY ecosystem)
- **Founders**: Not publicly disclosed

## Core Business
- **Primary industry**: AI-powered software development / No-code / Low-code development platforms
- **Target customers**: SMBs and enterprises across operations, finance, sales, and support teams who need internal tools without writing code; also individual builders creating apps and websites
- **Mission**: "Create the future internet, one app at a time" — enabling people to build software by describing it, so non-engineers can build, run, and iterate on tools without a traditional engineering team

## Products & Services
- **Caffeine Chat-Based App Builder**: The core platform where users chat with AI to create and update applications. Each chat session relates to a specific app being created or modified, with draft/live versioning for production updates.
- **Caffeine Ask**: A cross-app querying feature that reads across all apps built on the platform and answers questions in plain language — no dashboards needed.
- **Self-Writing Tech Stack**: A proprietary stack built on the Internet Computer Protocol (ICP) using Motoko, a programming language designed for AI. This provides security guarantees, prevents data loss during updates, and makes apps tamperproof and resilient.
- **OpenCloud / Private Cloud Deployment**: Apps can run on Caffeine's public cloud (with TEE privacy protection), on private cloud networks, or on single servers — with clean, exportable code and data to prevent vendor lock-in.
- **Deep Web3 Functionality**: Native smart contract interaction, token custody, and DeFi integration capabilities (currently restricted, planned for full unlock in 2026).

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: "Thousands of internal tools built without writing a line of code" (per company marketing)
- **Notable Investors/Partners**: Not publicly disclosed; the company is closely tied to the DFINITY Foundation and the Internet Computer Protocol (ICP) ecosystem
- **Growth Signals**: 
  - Expanding from a niche Web3-focused tool to a broader no-code platform targeting ops, finance, sales, and support teams
  - Maintaining a small, selective team (~33 employees) with deliberate, careful hiring
  - Planning major 2026 releases: private cloud deployment tools, open-source products, and full Web3 functionality unlock

## Competitive Advantages
- **First self-writing tech stack**: Unlike vibe-coding platforms like Lovable and Replit, Caffeine uses a purpose-built stack (Motoko + ICP) designed as a force-multiplier for AI, enabling more sophisticated app construction.
- **Anti-vendor-lock-in**: Apps are sovereign and portable — users own their code and data and can run apps anywhere, unlike competitors moving to proprietary cloud platforms.
- **Safety guarantees**: Tamperproof apps, resilience to server failure, auto-scaling, and protection against data loss during updates.
- **Cross-app intelligence**: The "Ask" feature reads across all apps for unified answers, a differentiator versus single-app tools.
- **Deep Web3 integration**: Native smart contract and token capabilities position Caffeine for the AI-agent economy and stablecoin-based payments.

## Strategic Focus
- **2026 roadmap**: Unlock full Web3 functionality, release open-source products for private cloud deployment, and expand capabilities for AI-agent integration with blockchain networks (including those operated by Stripe and Google).
- **Enterprise expansion**: Moving beyond individual builders to position as an all-in-one platform for internal tooling across business functions.
- **Engineering excellence**: Maintaining a small, senior team with end-to-end ownership and short feedback cycles.

## Why Work Here
- **Small team, real ownership**: Employees take features from idea to production, with direct influence on product direction.
- **Engineering culture**: Emphasis on "beautiful, reliable, performant experiences" and sweating details — not just shipping.
- **On-site in Zurich**: The company builds together in person, with quick conversations, tight loops, and shared context. On-site work is the norm.
- **Cutting-edge problems**: Work alongside researchers pushing on hard problems in AI, full-stack development, and on-chain applications.
- **Compensation & benefits**: Company equity offered, diversity-focused Employee Resource Groups, family medical leave, and healthcare benefits (per Built In).
- **Immediate impact**: Short feedback cycles mean what you build reaches real users almost immediately.
