Mythwright is a new games publisher, established by industry veterans with a proven track record of delivering successful titles. We care deeply about supporting creative teams and building long-lasting, collaborative relationships grounded in trust and shared vision. Our focus is on Steam, where we are curating a portfolio of Simulation, Management, Strategy, and adjacent niche games designed for passionate, highly engaged player communities. We believe in championing developers, supporting creative vision, and publishing games that earn lasting loyalty.

This is a 12-month contract.

We’re looking for a Senior Designer to work on a Simulation Game. This is a highly hands-on role, with the majority of your time spent directly working on the build. In this role, you’ll own major features and systems, helping shape the player experience from early prototyping through to polished implementation, all while balancing creativity, clarity, and scalability, enabling fast iteration and clean, maintainable systems. You’ll work closely with a small, multidisciplinary team to build imaginative and replayable simulation games that serve a distinct genre audience and connect with players.

• Own Core Systems and Features: You’ll be responsible for designing and driving key gameplay systems and features from concept through implementation. This is a hands-on role, so you must be familiar with Unreal Engine and comfortable prototyping, tuning, balancing, and iterating directly in the build while working closely with the team to bring ideas to life.
• Drive Playtesting and Iteration: You’ll use playtesting, feedback, and observation to refine the game throughout development. You’ll be expected to identify what’s working, what isn’t, and where design changes will have the biggest impact, then iterate quickly and thoughtfully in collaboration with the wider team.
• Collaborate across Disciplines: You’ll work as a senior designer within a small, collaborative team. You’ll communicate intent clearly, keep work aligned across disciplines, and help ideas move smoothly from concept to in-build implementation.

• Proven experience as a Senior Designer or equivalent on shipped games, ideally in the simulation genre.
• Strong experience designing and owning gameplay systems, mechanics, progression, or feature sets from concept through implementation in Unreal Engine.
• Comfortable working hands-on in-engine, with a practical understanding of how to prototype, tune, and iterate quickly.
• Strong grasp of systemic design, player motivation, balance, and long-term engagement.
• Excellent collaboration and communication skills across design, art, engineering, and production.
• Pragmatic approach to design, focusing on what moves the game forward and creates the best player experience.
• Experience using playtesting, feedback, and data to refine features and improve outcomes.
• Passion for simulation games and a drive to turn strong design into player delight.

Please note: This is a 12-month contract, remote-working position, open to anyone within the UK & Europe.

Our benefits include a 2-week company summer break and a 2-week winter break to rest and recharge, in addition to your normal holiday allowance.
