An Introduction to Karhoo
At Karhoo, we are creating the largest and most transparent marketplace for ground transportation: the Karhoo Mobility Exchange.
By aggregating ground transport around the world, with regulated/licensed taxi and PHV fleets, we will give greater choice to consumers and corporates alike, bring new opportunities and data for the private and public sector, and help to enable ‘smart cities’ for citizens everywhere.
Karhoo, the first fully-integrated global, neutral, booking platform for regulated Taxis and PHVs was bought out of administration in January 2017, funded by RCI Bank and Services, the financial services provider for the Groupe Renault brands in the world and for the Nissan Group brands mainly in Europe.
RCI Bank and Services operates at the crossroads of three challenging worlds: cars, banking and services and is backing Karhoo via Flit Technologies Ltd, a new venture funded by RCI Bank and Services.
We are adapting the latest and greatest technologies to push forward our product leaps and bounds. We are looking for a Lead Engineer capable of also working as a Technical Architect for one of the most technical and critical teams at this exciting and still very early stage in our company’s growth.
We’re looking for motivated individuals who can help push our Exchange Architecture further while maintaining a very high quality, changing the mindset of how we can do things and advance our platform further ahead from both a scalability point of view as well as performance.
If you’re looking for an opportunity to join a fast-paced startup that promotes an environment for collaborative culture and growth striving to deliver production quality code first time around then look no further!
Key Responsibilities
As a Lead Engineer of the Exchange Core team you will drive the Technical Architecture of the team responsible for 80% of our production traffic. The team is composed of two Senior SDE, two SDE and one SDET and is a very technical team working with a modern stack: Kubernetes, Golang, gRPC, Google Cloud, Seldon - building a microservice, event-driven platform (team owns approximately 80 microservices at the moment).
The team is looking for an experienced and very technical Lead Engineer that is capable to help them further their technical skills and take the platform to the next level in terms of scalability, reliability and development best practices.
As a Lead Engineer of the Exchange Core team you will be working closely with your team located in London. They will be looking to receive guidance and mentorship from you. Your time will probably be spent:
- ? coding in Golang and reviewing PRs
- ? writing or reviewing Software Design Documents or leading architecture sessions with the team or with other teams or partners
- ? mentoring the team, interacting with peers, product or other stakeholders in 1-1 sessions
Besides regular backlog execution and the related meetings (refinements, retrospectives, architecture sessions) we are also expecting you to work closely with product and provide technical guidance on new ideas and even occasionally travel to meet clients for workshops.
We are looking for someone who can own this critical area of our platform, understand it deeply and provide extremely clear technical architecture specifications. You should have a proven experience of previously leading teams (with or without line management). We are looking for a technical person who can work at different levels of abstraction and interact with both technical and non-technical stakeholders.
As a Lead Engineer at Karhoo the primary responsibilities are:
- Defining and executing on the technical roadmap for your teams in close collaboration with your Product and Engineering peers.

- Create Software Design Documents for the technical architecture and delivery plan for major platform initiatives. These initiatives might range from improving the testability, scalability, monitoring or security of the platform to introducing new and complex functionalities that might require coordinating with other teams inside the company such as CloudOps or Data.
- Making the operation of your products and services safe and sustainable. Leaders in Karhoo know the details of their services and prioritise the right improvements to keep things running smoothly.
- Take ownership. You'll drive execution of projects, in close collaboration with your Product peer, within your team and work with your peers to keep everyone aligned. You'll clearly and transparently communicate status to leadership and get help where needed to unblock your team.
