Full Job Description
Role Summary

Weekend is looking for a Senior Software Engineer to join our Platform Team - the team that owns the foundational backend services powering all of Weekend's AI-powered games. You'll work on identity management, payment systems, leaderboards, party systems, controller integrations, and developer tooling. You'll also help bring Weekend to new platforms like TVs and consoles, and contribute to the agent harnesses we're building to autonomously develop new platform features.

This is a high-ownership, high-impact IC role at a time when the team needs to move fast across a broad scope. You'll be a technical partner to game teams and other stakeholders, driving platform services from design through production.

This job opportunity offers a hybrid work arrangement, and we are specifically seeking candidates who are comfortable with on-site attendance in our Bay Area office 2-3 times per week and are either currently residing in or near the Bay Area or willing to relocate for on-site work.

What You'll Do at Weekend
  • Expand Weekend's footprint to additional TV and console platforms, building and maintaining the platform-specific integrations each one requires
  • Partner with game engineering teams to scope cross-cutting capabilities such as social features and identity, translating shared needs into reusable platform services and delivering them end to end
  • Develop and enhance the team's agent harness, extending its capabilities to debug issues, handle platform support requests, and investigate incidents autonomously
  • Expand subscription systems to support additional payment providers as well as TV-platform account and billing systems
  • Build features that ensure a consistent customer experience across all of Weekend's games, such as social features and leaderboards
  • Serve as a reliable on-call partner for the team's broad platform support scope
We're Excited About You Because You Have
  • 5-8 years of software engineering experience, with a strong track record owning backend or platform services
  • Experience building foundational infrastructure that multiple products depend on - identity/auth, payments, subscriptions, shared APIs, or similar
  • Comfort serving as the primary technical contact for product and design partners: scoping cross-cutting work, pushing back on scope creep, and surfacing 80/20 opportunities
  • Deep sense of ownership across the full software development lifecycle - from requirements through production support
  • Ability to develop a strategy or plan for solving a problem without much direction, execute flawlessly, and build repeatable processes
Bonus Points
  • Experience in gaming, real-time/multiplayer systems (party, leaderboards), or other consumer products at scale
  • Background building internal developer tooling or improving developer experience with a bias toward automation
  • Experience building AI/LLM tooling and agentic workflows
Our Stack
  • Typescript, Golang, Node.js, React, SQL, AWS, Kubernetes
The Hiring Process
  • Stage 1 (Preliminary Video Call): with a member of our recruitment team
  • Stage 2 (Virtual Engineering Panel): Manager Screen (30 min) + Technical Screen (60 min)
  • Stage 3 (Onsite Interview): with various partners and team members
  • Stage 4(Founder Chat) with our Founders

As an AI company, we're a huge believer in the value of AI tools. That being said, the interview process is intended as a conversation - we want to get to know you and your experience. Please refrain from using AI tools during your conversations unless otherwise specified.

What's in it for You
  • Your medical, dental, and vision insurance is 100% covered by Weekend, for yourself and all dependents and we match 401k!
  • We offer a flexible, hybrid work-from-home and in-office work model.
  • We offer unlimited paid time off (enforced 2-week minimum), 14 paid holidays, 40 hours of bereavement leave, and unlimited sick days.
  • Our generous parental leave policy includes 24 weeks at 100% pay for birthing parents and 12 weeks at 100% pay for non-birthing parents.
  • We offer visa support for eligible candidates, making relocating for the job smoother and more streamlined.
