Our platform transforms complex user data into clear, actionable insights - helping customers like Lego, Nike, Netflix, and Apple build digital experiences that truly connect.

Now, we’re evolving how we build too - by embracing AI-powered development to move faster and focus on what matters most: creating great user experiences.

The role

We’re looking for a Full Stack Engineer to help shape the future of how we build at Optimal. You’ll work across our stack - using React, Ruby on Rails, and AWS - while integrating AI coding tools to speed up delivery and improve our developer experience.

This is a role for someone who loves impact, experimentation and innovation - blending your engineering skills with an early-adopter mindset around AI productivity.

What you'll do:

Build impactful features across our platform

Work closely with Product and Design to solve real problems for our customers

Take ownership of projects from conception to completion

Collaborate and contribute to our product strategy and goals

Define and mentor the team on AI-assisted workflows and best practices

What you’ll bring:

Proven experience delivering software end-to-end with our stack (React, Ruby on Rails, AWS)

Passion for solving customer problems through impactful solutions

Strong collaboration skills and sense of ownership

Experience with AI driven product development and coding

A leadership and entrepreneurial mindset, with curiosity for shaping AI-assisted workflows

What’s in it for you:

Competitive salary + Employee Share Option Plan (ESOP)

Annual wellbeing allowance

Home office set-up support

An additional day off on your birthday

Enhanced parental leave for primary and secondary caregiver

The chance to shape our engineering culture and be part of a high performing team
