We are a start-up between pre-seed and seed investment rounds disrupting the construction industry. Our crew is less than 10 members with several ex-Revolut employees among founders. One of the founders has built up a ~$100,000,000 revenue construction business and provides key industry know-how, contacts, and a test environment tool. Everybody is working remotely, although we would like to hire more developers in London. We are ‘connecting construction’ with a unique, transparent, and efficient workforce and project management app connecting tradesmen and subcontractors. We will eventually connect the whole construction supply chain, including main contractors and owners/developers.
Construction accounts for 13% of global GDP and 7% of the world’s workforce and has had relatively little digital adoption to date. There are few places where you will have the opportunity to make a product with as meaningful and tangible a business impact on the world.
We are looking for a lead backend engineer with 5+ years of experience who:
- Has experience leading projects.
- Can explain the difference between TDD, BDD, DDD, and other *DD methodologies.
- Can improve event streaming to make event sourcing.
- Understands that DevOps is not a person, but a set of practices.
- Can wrap code in a jar, pack it in Docker, and set up a CD to deploy it to the cloud.
- Has JVM experience, ideally Java or Kotlin.
- Has experience building web applications.
- Can explain the difference between 4xx and 5xx errors and justify using PUT and POST methods.
You will be doing:
- Leading and building up the backend engineering team as the company scales.
- Coding alongside other engineers.
- Maintaining the app infrastructure, being responsible for security, and striking a balance between fast implementation of features and fundamental app architecture.
- Designing DB tables and queries using the best practices for indexes.
- Managing DB transactions for backend requests.
- Implementing a CRUD service, agreeing on the schema with web and mobile engineers, and providing them details with OpenAPI.
We are open to all ideas and initiatives, but you will be expected to prove/quantify your point of view and suggestions.
Offer: Salary, share options at the start and with company growth. London, starting remotely, at least 3 office days in a few months.
Screen call (30 minutes), Technical interview with engineers (1 hour), Architecture interview with CTO (1 hour), Culture, team, and product conversation with one of the founders (40 minutes).
