## Job description

We’re looking for an Optimisation Engineer to join the Stellar Entertainment mission!

The Studio

We are a video game development studio with offices in Guildford, UK and Utrecht, Netherlands. Sitting within the heart of thriving communities of game developers and publishers, we focus on quality and excellence, and our partners and players are always at the front of everything we do.

Games are not just about gameplay. We believe in the importance of balancing every single aspect of a game that you, as a player will interact with; what you see, how you play and how it makes you feel.

An exciting new project is taking shape at Stellar. You'll be joining a specialist team who are ready to provide technical solutions and optimisations.

## The Role

As an Optimisation Engineer, you will be a part of the core tech team working closely with graphics, gameplay, engine and tools. Day to day you will:

- Profile and analyse CPU and GPU workloads, identifying performance bottlenecks
- Define, track, and enforce frame time, memory, and bandwidth budgets across all game systems in collaboration with leads and the Technical Director.
- Collaborate with artists, designers, and programmers to ensure visual quality
- Provide hands-on mentoring and code review support to mid-level engineers on performance-sensitive coding practices

## Requirements

What we’re looking to see on your CV:

- Experience in game development through all stages of the process from design to shipping
- Experience in the games industry, in a performance, platform, or core technology role.
- Strong C++ skills, including knowledge of multithreading, software design patterns, and systems architecture
- Experience and understanding of low-level CPU and GPU profiling tools
- Experience working with large code bases
- Familiarity with game engine architecture across multiple engines
- Good problem solving and debugging skills

Bonus points for:

- Any additional coding languages under your belt
- Understanding of hardware architecture

## Benefits

What you can expect from us:

- Flexible hybrid working (we work 3 days per week on-site, and have core hours of 10:00 – 16:30)
- Holiday Accrual Scheme
- International AAA game projects;
- Access to cutting-edge hardware;
- Discretionary bonus scheme
- Private Healthcare Plan incl. Dental and Eye care
- Pension Plan
- Life Assurance
- Employee Assistance Programme - Wellness Support
- Regular Team Incentives and Social Events

We’re on an important journey with our teammates, candidates and industry partners to tackle barriers to equality and promote diversity, inclusion and accessibility across the markets we work in. If you need any support during the interview process or any feedback on our processes, please let us know.

We're unfortunately unable to provide visa sponsorship or relocation support for this role, so you'll need to be based in the UK with the Right to Work here.

## About Stellar Entertainment Software Ltd

## Company Overview
- **One-liner**: Stellar Entertainment is a people-centric game development studio that partners with high-profile industry partners to create high-quality interactive entertainment software.
- **Entity Type**: Private (Bootstrapped/Independently owned)
- **Headquarters**: Guildford, United Kingdom (also has an office in Utrecht, Netherlands)
- **Founded**: 2016
- **Founders**: Not publicly available (scan of leadership shows alumni from AAA studios)

## Core Business
- Primary industry: **Video Game Development** (Ready-made interactive leisure and entertainment software)
- Target customers: B2B (publishing partners) and B2C (gamers/players)
- Mission: "To create & amaze" — delivering work of exceptionally high quality that speaks for itself.

## Products & Services
Stellar Entertainment is known as a **co-development partner** rather than an original IP holder. They work on high-profile franchise titles:
- **Vehicle Handling & Physics Engineering**: Specialized in realistic driving and vehicle physics for racing/simulation games.
- **Full-Game Co-Development**: Partnering with major publishers to build AAA-quality titles.
- **Rendering & Graphics Technology**: Cutting-edge rendering engineering and technical art.

Specific game titles are not listed on their public site, but their expertise and LinkedIn talent patterns (alumni from Splash Damage, Criterion Games, Wargaming) suggest work on major racing and action titles.

## Market Standing
- **Valuation**: Not publicly available (Private company)
- **Annual Revenue**: Not publicly available (SIC code 62011 - Interactive leisure software)
- **Total Funding**: Not publicly available — the company appears to be self-funded or operating on a project-based, fee-for-service model.
- **Notable Partners & Clients**: High-profile (but unnamed) industry partners; member of UKIE (UK games trade association); supports Women in Games.
- **Growth Signals**:
    - **Headcount**: 55 employees (+8.5% YoY)
    - **Geography**: Operates across 6 countries (UK, Netherlands, Spain, France, South Korea, Austria)
    - **Active Hiring**: 8 active job postings (as of mid-2026), up +100% quarterly and down -27.3% yearly — indicating a stabilising but active growth phase.

## Competitive Advantages
- **Talent Magnet**: High retention of senior and director-level talent (28% Senior, 12% Director). Ex-employees go on to major studios (nDreams, Criterion, Jagex, Aardman), suggesting excellent training and career launchpad.
- **Specialized Expertise**: Deep specialization in vehicle handling, physics, and rendering engineering gives them a defensible niche in a market where such talent is scarce.
- **"Stellar Code" Culture**: Emphasizes trust, flexibility, and taking on "the difficult work" so partners and players can enjoy an unparalleled experience. Known for a high-quality bar without a "crunch" culture.

## Strategic Focus
- **International Expansion**: Has a formal international placement scheme allowing UK employees to work in the Netherlands (Utrecht office).
- **People-First Scaling**: Growing headcount by 8.5% annually while maintaining a strong culture. Focused on attracting "fresh faces to decorated veterans."
- **Partnership Model**: Continues to deepen relationships with major publishers rather than developing original IP, reducing financial risk and allowing focus on pure engineering/art excellence.

## Why Work Here
- **Culture & Flexibility**: "Life happens — we work a hybrid flexible working system." Core days in the office with flexible hours. Remote and hybrid roles available (e.g., Principal Rendering Engineer can be remote UK).
- **Benefits**:
    - 24 days holiday (UK), 25 days (NL), increasing to 30 days with tenure
    - Office closed over Christmas period
    - Private medical insurance (UK) with online GP, nutritional support, wellbeing portal
    - Dental, optical, and hearing support
    - Flu jab reimbursement
    - Discretionary bonus scheme with regular check-ins
    - Pension scheme
    - Cycle-to-work scheme
    - International working scheme (relocation to Netherlands)
    - "13e maand" (13th month payment) for NL employees
- **Mental Health**: Dedicated Employee Assistance Programme and wellbeing events year-round.
- **Social Culture**: Summer socials, Christmas parties, weekly Friday "hangout hour" at 4pm.
- **Diversity & Inclusion**: Supports Women in Games (with two ambassadors at Stellar), UKIE membership, and actively encourages all candidates regardless of background.
