The job
We’re building simple, meaningful casual games for adults — experiences designed to support mental clarity, cognitive stimulation, and long-term brain engagement.
We’re not creating complex strategy systems or immersive fantasy worlds. Our games live inside a health-focused ecosystem. They are:
Lightweight
Accessible
Purpose-driven
Designed for daily use
We believe in simplicity done exceptionally well. Elegant mechanics over complexity.
As a Game Designer, you’ll craft intuitive casual game experiences that support cognitive longevity while driving engagement and retention.
You’ll design core mechanics that are easy to understand, satisfying to interact with, and meaningful to return to — every day.
You’ll work at the intersection of game design, behavioral science, and product thinking.
Your Experience
Must have:
Experience designing casual or hyper-casual games
Strong systems thinking with a simplicity-first mindset
Understanding of retention mechanics and player motivation
Comfort working with product metrics and A/B tests
Clear communication and structured documentation skills
Interest in cognitive health or behavioral science
Familiarity with mobile development (Unity is a plus)
What you'll be doing
You'll be responsible for:
Designing simple, intuitive casual game mechanics
Developing and iterating on engaging core loops
Balancing progression and difficulty scaling
Creating clear, structured, actionable game design documentation
Collaborating closely with product, analytics, and development teams
Improving mechanics using data insights and user feedback
Running experiments and contribute to A/B testing initiatives
- Collaborating closely with product, analytics, and development teams - plus artists, animators
Your decisions will be grounded in measurable outcomes — not assumptions.
3 month contract - start ASAP (please note benefits do not apply to this role)
How we work
We’re a mission-led, product-driven team. We move fast, stay focused and take ownership – from brief to build to impact. Debate is encouraged. Decisions are shared. We care about craft, ship with purpose, and always raise the bar.
You’ll be working with people who take their work seriously, not themselves. It takes commitment, resilience, and the drive to keep going when things get tough. Because better health outcomes are worth it.
What you'll get
We support impact with meaningful reward. Here’s what that looks like:
- Competitive salary and annual reviews
- Opportunity to participate in Flo’s performance incentive scheme
- Paid holiday, sick leave, and female health leave
- Enhanced parental leave and pay for maternity, paternity, same-sex and adoptive parents
- Accelerated professional growth through world-changing work and learning support
- In-person collaboration and work in a hybrid model, with 3 days per week spent in the office
- 5-week fully paid sabbatical at 5-year Floversary
- Flo Premium for friends & family, plus more health, pension and wellbeing perks
