Unity Engineer Manager Jobs in California (NOW HIRING)

The opportunity
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.
What you'll be doing

• 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.

What we're looking for

• 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
