Founding Product Engineer

About the role

You’ll develop AI‑powered workflows and product experiences that make email and SMS easier for Shopify merchants. Our platform already combines messaging, automation, CRM, analytics and forms across web and mobile. Your work will make those capabilities simpler to understand and use. This is a full‑stack role with a focus on frontend and AI. You’ll take features from an idea to production, building the interface, backend logic and database changes they need, while collaborating with an established engineering team in Europe.

Responsibilities

• Own features from early sketches through release: build the frontend, write backend logic and APIs, make database changes, and test the complete experience.
• Build AI features from model integration through to the interface, making them useful, responsive and reliable for merchants.
• Design clear interactions around AI: show what is happening, make suggestions easy to edit, and give merchants control over what gets published or sent.
• Test AI features for usefulness and reliability. Build clear loading, empty and error states, and improve the experience when results fall short.
• Watch how merchants use what you ship, remove friction and improve both the feature and its design with the team.
• Build with coding agents such as Claude Code and Codex; demonstrate task scoping, code review, testing, and correction of generated code.

Requirements

• Proven ability to build working software and explain the problem it solves and the choices you made; personal, open‑source, or customer‑facing projects count.
• Ability to independently build and debug across the stack (frontend, APIs, backend logic, relational databases). Strong in TypeScript and React or Next.js, comfortable with NestJS and PostgreSQL; Flutter experience is a plus.
• Strong eye for good design and ability to translate it into usable interfaces, with attention to layout, interaction details, accessibility, and responsive design.
• Experience building or seriously experimenting with AI features, understanding model APIs, context, retrieval, evaluation, and ability to assess results.
• Capability to scope a useful first version, make practical trade‑offs, take features through testing, release and follow‑up fixes; knows when to seek a second opinion while keeping work moving.
• Early‑career candidates are welcome if they have substantial personal projects, open‑source work, or self‑built products; focus is on ability and learning speed rather than a long employment list.

Benefits

• 15 paid vacation days, 10 company holidays and 5 paid sick days each year.
• Medical, dental and vision insurance.
• 401(k) employer match of up to 4% of eligible pay.
• Annual offsites with the whole team; future offsites in Norway with optional sauna and ice‑cold sea dip.
• Work computer and necessary equipment provided.

Pay

$120,000–$150,000 annual base salary. We’re open to going above this range for candidates with exceptional experience and seniority. Bonus and equity opportunities are also available.

Schedule

Full‑time role. Hybrid in Austin, with at least three days together in the office each week.
