Senior Full-Stack Engineer, Webshops

About the role

We're hiring for a Senior Full-Stack Engineer to join our LiveOps team. We are building a first‑party webshops platform that lets game developers route players to browser‑based stores instead of in‑app purchases; unlocking up to ~20% additional margin versus traditional platform fees. You'll join a small, senior founding pod responsible for shipping the initial GA product and rapidly iterating it with real game studios. You will own large pieces of both the player‑facing webshop experiences and the multi‑tenant backend services that power them. You'll work closely with a small team in a highly autonomous, AI‑native development environment where using AI tools is expected. The webshop is the player-facing surface of Unity's broader Commerce Management Platform; a new initiative that gives developers a single dashboard to manage their entire digital catalog, pricing, promotions, and payment providers across mobile app stores, web, and PC. More than 70% of the top 1,000 mobile games are already built with Unity, and the IAP SDK already manages their in-game economies. The web shop is what closes the loop: a branded, direct-to-player storefront that's natively integrated with the catalog and entitlements developers already manage through Unity, with Stripe as the launch payment partner. This is a hands‑on, product‑minded role for someone who loves building from 0 to 1, moving fast with a small team, and shaping not just the code, but the product and the engineering model itself.

Responsibilities

• Design, build, and maintain conversion‑focused webshop front‑ends and multi‑tenant backend services with strong reliability and SLA expectations.
• Ensure end‑to‑end quality across the stack, including performance, security, observability, and maintainability.
• Work in a small team to ship the initial GA version of Unity's webshops product.
• Rapidly iterate on features based on real customer usage and feedback.
• Prototype and refine features directly with game teams integrating the webshop into their titles.
• Collaborate with the team to shape requirements, propose UX flows, and influence the roadmap.
• Translate high‑level product ideas into concrete specs, technical designs, and shipped software.
• Use AI tools aggressively throughout the development lifecycle for coding, scaffolding, refactoring, debugging, and exploratory design.
• Help the team define what AI‑first engineering best practices look like in reality.
• Help define the technical foundations that will support many shops and customers; i.e. multi‑tenancy, configuration, extensibility, etc.
• Influence how this effort evolves into a larger platform, organization, or dedicated product line over time.

Requirements

• Extensive full‑stack engineering experience, with a proven track record of independently building and shipping user‑facing web products end‑to‑end.
• Strong front‑end skills with modern JavaScript/TypeScript frameworks (e.g., React, Vue), with attention to UX, performance, and conversion‑oriented design.
• Strong backend skills building scalable, multi‑tenant services and APIs, including reliability, observability, and performance tuning in production.
• Comfortable working across the full stack, from database to UI; language‑flexible, with Golang experience as a plus.
• Actively uses AI today to enhance development and is excited to push the limits of AI‑assisted workflows.
• Experience working closely with PMs to shape requirements and make tradeoffs, comfortable with ambiguity and incomplete specs, and inclined to propose solutions rather than wait for direction.
• Genuine interest in games and the gaming ecosystem.
• Thrives in small, autonomous teams with high expectations and a strong bias for shipping v1s quickly.
• You might also have
• Experience in game monetization, webshops, e‑commerce (especially loyalty, personalization, or growth mechanics), payments and checkout infrastructure, or developer‑facing platforms.
• Additional information
• Relocation support is not available for this position
• Work visa/immigration sponsorship is not available for this position
