Hello!
Innersloth is a small team scattered mostly in North America. We released Among Us in 2018 and its popularity and ongoing development updates means we need help with our growing backend team! We’re looking for someone to help us build and refine the real-time multiplayer systems behind Among Us and our future titles. Your hard work will affect millions of players around the world (and help our other Backend Programmers take a nap).
Your focus will be on networked gameplay: designing, implementing, testing, reviewing, and maintaining the neworked gameplay systems. You'll also contribute to our broader backend systems and infrastructure, including matchmaking, server-authoritative security and anti-cheat, and deployment pipelines.
You’ll report to our Backend Programming Director and take technical direction from our Backend Architect, working alongside the rest of the Backend team and our external development partners. We don’t want to overscope this, but because we are a small team, sometimes responsibilities overlap - a willingness to learn and help is essential. You will not be working alone, and our team prioritizes providing support and ensuring you are thriving in your role.
We especially encourage marginalized groups and people from underrepresented backgrounds, genders, and locations to apply. Diverse voices make Innersloth better, and we strive to continue creating a diverse and welcoming space from the ground up.
Please note this is not an entry-level position, but we'll consider strong candidates with general experience working in games, backend development, or distributed systems that accounts for the required skillset, even without 5+ years of "official" experience matching the expectations set below. Please absolutely include these things in your application!
What we're looking for: Proactivity, independence, and accountability are extremely important for this position. If you show an aptitude for working well with others, handling conflict, and understanding backend technology, we want to hear from you! AI-dependent workflows are not a fit for this position. Candidates should be able to demonstrate their work, reasoning, and problem-solving without AI assistance.
The following points outline the experience and skills that we strongly prefer. None of these are strict dealbreakers, but reflect the type of experience we feel would lead to finding the right candidate for this position.
Our expectations:
- 5+ years of experience and excellent knowledge of C#
- Excellent knowledge of server-side programming
- Experience with version control/asset management systems
- Excellent written and oral communication skills and the ability to clearly articulate your ideas, and suggestions
- The ability to give, process, and accept feedback
- Can collaborate and work well in a team-based, dynamic, cross-functional setting
- Highly organized and able to work independently
- Strong attention to detail
- Experience and comfort diving into an existing codebase
- Experience with real-time multiplayer games, particularly server-authoritative models
- Experience with real-time state synchronization, including physics state synchronization
- Strong debugging and investigative skills
- Experience creating maintainable, scalable systems and architectures
- Experience with, or the ability and willingness to learn, technologies including RUDP (we use Hazel), NATS Messaging, MongoDB, Orleans, Postgres, Redis, Kubernetes, Docker, Multiplay, Linode, and Ubuntu
- Collaborative, respectful, and kind approach to working with others
- Experience following and refining inter-department processes (task tracking, asset handoff, sprints, etc)
Nice to have:
- Experience working in games, particularly live service games
- Comfort with Go and/or Typescript
- Experience with low level network programming
- Experience with designing or implementing skill-based matchmaking algorithms
- Familiarity with the Among Us IP
- Education related to the role is an asset but not required
What you'll be doing:
- Design, implement, and review networked gameplay systems using appropriate server-authoritative, host-authoritative or client-authoritative models
- Design, implement, and review state synchronization, replication, prediction, interpolation, and reconciliation systems
- Profile and optimize networked gameplay systems for reliability and performance
- Implement general backend features to support multiplayer game titles
- Contribute to backend infrastructure design, implementation, operations, and maintenance
