Job description
Over the next few years, we're evolving our platform from a strong foundation into a truly intelligent logistics marketplace. You'll help design and build systems that:
- Model true job-level costs in real time, enabling smarter, more dynamic pricing
- Deepen our driver platform, embedding into their daily workflows and unlocking new revenue opportunities
- Create a two-sided marketplace, including buying and selling non-core jobs between drivers to maximise utilisation
- Scale reliably, as we grow volume, complexity, and ambition
This is a role for engineers who enjoy solving ambiguous, high-impact problems and shaping how a platform evolves at scale.
Why this role matters

How our engineering teams deliver
We're a product-led, agile organisation. Most teams run Scrum with two-week sprints, but we care far more about outcomes than rituals. Engineers are trusted to adapt processes, challenge assumptions, and improve how we work.
Senior engineers here are not heads-down implementers, you'll:
- Work closely with product, data, and commercial stakeholders
- Influence technical direction and architectural decisions
- Balance speed with long-term sustainability
- Regularly ship meaningful improvements to production
Our Technology:
We're pragmatic and cloud-first, choosing the right tools for the problem:
- Cloud: AWS
- Backend: Java (Spring), Python
- Frontend: JavaScript (Vue.js)
- Other: TypeScript where it makes sense
- Legacy: A PHP stack we're actively migrating away from (because scale-ups are real life)
You don't need experience in everything - we value strong fundamentals and good engineering judgement over keyword matching.
What you'll be doing:
- Designing, building, and operating production-grade systems that scale
- Tackling complex technical challenges across backend, infrastructure, and data flows
- Writing clean, pragmatic, well-tested code with long-term maintainability in mind
- Collaborating with technical and non-technical stakeholders to shape solutions
- Championing testing, observability, and quality improvements
- Mentoring engineers and raising the technical bar across the team
Requirements
- Experience in a scale-up or fast-growing product environment
- Strong backend engineering skills (Java, Python, or similar)
- A solid understanding of distributed systems, scalability, and performance
- Experience with CI/CD, modern deployment practices, and cloud infrastructure
- Comfort working with ambiguity and evolving requirements
- A bias toward action - shipping value quickly, then iterating
- A collaborative mindset and the ability to influence beyond your code
Bonus points for exposure to marketplaces, logistics, pricing, or e-commerce systems.
