PARts DB builds the B2B fitment data and catalogue platform that sits underneath the automotive parts supply chain. When a workshop, retailer or distributor can tell you in seconds whether a part fits a given vehicle, that answer came from a platform like ours.

We have 25+ years of proprietary fitment data behind us - one of the deepest data sets of its kind in the region - and the backing of GPC Asia Pacific. That combination is unusual: the data depth and stability of a large group, with the pace and short decision paths of a team small enough that your work is visible.

Vehicle fitment is a genuinely hard data problem. High cardinality, messy real-world sources, unforgiving accuracy expectations, and commercial weight behind every answer. It is not CRUD.

The role - and why we have pitched it where we have

We would rather hire someone with the capability to lead a stream and grow into the title than someone who already has the title on their CV. If you are a solid Senior Developer who has been shaping technical design, lifting the people around you and doing lead work without the badge, this is the role where you get the badge - and the support to grow into it.

You will join as a Senior Engineer reporting to the Head of Engineering, with a mapped path to Technical Lead: a defined set of readiness indicators, a development plan against them, and a manager who will tell you plainly what is still missing. Move faster than expected and the title follows.

What you will be doing

- Leading design and delivery of the most complex, novel and highest-risk work in your stream - cross-system builds, migrations, and performance and scalability problems.




- Owning the technical design of what your stream ships and making the architectural calls that go with it: security, performance, scalability, data integrity and operational cost.
- Staying hands-on. This is a technical leadership role, not a step away from the keyboard.
- Setting the quality bar - thorough code review, engineering-led QA, automation, integration testing and CI/CD discipline.
- Owning root cause analysis and durable resolution for significant production incidents in your stream.
- Mentoring Developers, Juniors and Graduates through pairing, review coaching and input into their development plans
- Working directly with Product Managers, business stakeholders and vendors, translating technical trade-offs into decisions they can act on.
- Growing into the lead: contributing to estimation, planning and stream direction, deputising for the Technical Lead, and building the people-leadership side deliberately rather than by accident.
- Setting the standard for AI-assisted development - high throughput on complex work with rigorous verification, and clear judgement about where the tools can and cannot be trusted.

What we are looking for - capability, not years

We are assessing what you can do and how fast you grow, not counting service.



In practice this capability tends to show up somewhere around the five-year mark, but if you have it earlier, we want to hear from you.

- You are the person complex work already gets routed to, and it comes back done.
- You make design calls and can explain clearly why you made them.
- You lift the people around you - review feedback that teaches, not just corrects.
- You are comfortable with ambiguity: you interpret the problem, shape the solution and own the outcome.
- You communicate rather than go quiet, particularly when something is going wrong.
- You want to lead a team, and you are honest about the parts of that you have not done yet.

Your technical background

- Strong backend depth in C# / .NET Core, with solid front-end capability in React (Next.js an advantage).
- Proven experience building and scaling modern web applications, APIs and services in a cloud-native SaaS environment.
- Azure preferred. We are open to AWS or GCP backgrounds where you have moved between platforms before or can show you have done the homework to pick Azure up quickly.
- Database design across relational and non-relational stores, with a focus on performance and data integrity.
- Secure development practice you can embed in a team, not just apply yourself.
- CI/CD and DevOps as part of how you work, not a separate function.
- Expert and judicious use of AI development tools, with the ability to teach and standardise that usage.
- Strong Agile Scrum fluency; experience working with offshore teams is an advantage.
- Degree in Computer Science, IT or Software Engineering, or equivalent practical experience.
