Software Developer jobs in United Kingdom

Hi there!

We're looking for a C++ Engineer (Unreal Engine) to join the growing team at Heroic Labs. Our cornerstone offerings—Nakama, Hiro, Satori, and Heroic Cloud—comprise the Heroic Game Stack, an integrated platform delivering unparalleled performance and flexibility.

We are simplifying the lives of game developers and providing incredible technology that can be integrated into any game on any platform as easily as possible. Nakama is already powering many games around the world, including multiple Top 50 titles on the Apple App Store and Google Play.

Heroic Labs works with independent developers, mid-tier and AAA game studios, and many publicly listed, Fortune 500 companies across the globe to power games that individually make over 90 billion requests per month into our infrastructure.

We're seeking an experienced C++ Engineer specializing in Unreal Engine to help build and maintain our client SDKs and work directly with game studios implementing our technology stack.

You’ll be responsible for developing and maintaining our C++ and Unreal Engine SDKs, with particular emphasis on network programming and real-time multiplayer functionality. Working closely with game studios during their onboarding process, you’ll also implement feature requests and debug networking issues.

This is primarily a technical implementation role where you’ll collaborate with both our internal engineering teams and external game studios to deliver high-quality solutions that scale to millions of players.

SDK Development & Maintenance:

• Develop and maintain C++ SDKs and client libraries for Unreal Engine
• Focus on network programming and real-time multiplayer functionality
• Optimize client-server communication patterns for performance and reliability
• Create comprehensive unit tests and integration tests for SDK components

Customer Implementation & Support:

• Work directly with game studios during onboarding, implementing agreed-upon features
• Debug networking issues in customer projects
• Collaborate with customers to design and implement scalable multiplayer architectures
• Provide technical guidance on best practices for integrating our technology
• Occasionally embed with customer teams for extended implementation periods

Technical Excellence:

• Write clean, maintainable, and well-documented C++ code
• Implement advanced networking features (latency compensation, state synchronization, prediction)
• Optimize memory usage and performance for various platform targets
• Contribute to architectural decisions for client-side implementations

Cross-functional Collaboration:

• Collaborate with Developer Relations team to ensure comprehensive SDK documentation and understand common implementation challenges
• Work with Product and Engineering teams to align SDK features with platform capabilities

We would love to hear from you if you have:

• 5+ years of experience with C++ development in game development contexts
• Strong experience with Unreal Engine C++ development
• Deep understanding of network programming concepts (TCP/UDP, client-server architecture, latency compensation, state synchronization)
• Experience building multiplayer games and/or multiplayer netcode
• Proven ability to debug complex technical issues in production environments
• Strong understanding of memory management and performance optimization in C++
• Experience working with SDKs or client libraries
• Excellent problem-solving skills and attention to detail
• Ability to work independently and manage multiple priorities

We’d be super excited if you have:

• Experience with other game engines (Unity) and languages (C#, Go, Lua, TypeScript)
• Understanding of backend game services and server architecture
• Experience with WebSockets, gRPC, or other modern networking protocols
• Knowledge of authentication protocols and security best practices in multiplayer games
• Experience in Professional Services or customer-facing engineering roles
• Experience with cross-platform development (PC, console, mobile)

For the past 10 years, Heroic Labs has been on the forefront of providing cutting edge technology to the games and entertainment market. We do this because we love developers and we love games!

We always choose the right tool for the job. We believe that with the right tools, you can have a big impact with less hassle. We believe in small teams. Small teams are fast and nimble. Small teams mean less bureaucracy and less management and more getting things done.

Location: We're looking for candidates based in Europe or Canada, with flexibility to work remotely. We have team members across 4 different timezones and value asynchronous collaboration.

Compensation:

• Competitive salary (we don't use remote as an excuse to pay less)
• Unlimited vacation policy. Plus we require you to take at least 2 weeks off each year (and observe local holidays)
• At least yearly company all-hands and getaways
• Pick your own equipment. We recommend Macs, but we don't worry if you choose something else!
• Work with a loving team that treats everyone as family

Send an email to us with your resume, and a cover letter highlighting why you'd like to join Heroic Labs. If you have any technical content, open-source contributions, or video content you've created, we'd love to see it!

After you apply, you are going to hear back from us, even if we don't seem like a good fit. In fact, throughout the process, we strive to make sure you never go more than seven days without hearing from us.
