• You don’t clock in for a paycheck; you clock in to outperform yourself in a high-frequency trading environment.
• You understand the stakes—milliseconds can make or break trades, and precision is everything.
What We Expect:
• Develop and maintain scalable backend systems using Python.
• Design and implement REST APIs and socket-based communication.
• Optimize code for speed, performance, and reliability.
• Collaborate with frontend teams to integrate server-side logic.

• Bachelor’s degree in Computer Science or related field.
Nice-to-Have Skills:
• Past experience in fintech, trading systems, or algorithmic trading.
• Experience with GoLang, C/C++, Erlang, or Elixir.
• Exposure to trading, fintech, or low-latency systems.

About the Tech
Technology and our people is what makes Tide possible. We work in autonomous teams where backend, iOS, Android, web, QA, DevOps, agile coaches, data experts and product owners solve difficult problems together to get the job done. We self-organise and discuss technical challenges and set our own guidelines in the different Community of Practices.
On the backend we see Java 8 as legacy and use Java 11+ for our micro-services. We provide RESTful APIs to our colleagues in the frontend, but also use gRPC for internal service-to-service communications. Spring Boot is our work horse, but we are open to new experiments. We are cloud-native and run everything on AWS. You’ll see containers (Docker), queues (SNS+SQS) and events everywhere. The nature of our business naturally fits with relational databases, but we have also found some use cases for NoSQL.
Our frontends have done an incredible job at consuming our APIs and providing the best UX to our members. They are fully native Android and iOS apps or Angular 2+ web apps. DevOps provides vital infrastructure and operations support.
About You
We’re an international scale up, we’re busy! If fast paced environments, cross team exposure, inquisitive freedom and the ability to have a real impact on a rapidly growing scale up appeals to you, then you already have the mind of a Tidean. If you have that along with the following experience, we’d love to hear from you.
The non-negotiables:
- Good commercial experience building server-side applications and detailed knowledge of the relevant programming languages for your stack (i.e Java 8 or newer).
- Sound knowledge of a Java backend framework (e.g. Spring/Spring Boot).
- Exposure to microservices and implementing and consuming RESTful APIs.
- A mindset of delivering secure, well-tested and well-documented software.
- Experience with relational databases.
The highly desirables:
- Exposure to continuous integration, delivery and deployment.
- Some experience integrating to third parties.
- Comfortable working in agile methodologies, ideally Scrum.
- Exposure to common development tools such as IntelliJ, Git, Jira, etc.
Why Tide?
Tide is the leading provider of UK SME business accounts and one of the fastest growing FinTechs in the UK. That’s not an unfounded boast - we have over 200,000 members (what we like to call our customers, over two percent market share, and have raised over £120m in funding.
SMEs have been underserved and overlooked by traditional banks for years. In an entrepreneurial age where everyone is expected to take a shot, traditional banks have not evolved with the needs of the market. That’s where Tide comes in. With quick on-boarding, low fees and innovative features, we thrive on making data driven decisions to help SMEs save both time and money.
We’re also one of LinkedIn’s top 10 hottest UK companies to work for, winner of Best Use of Technology (Growth Finance Awards); Best Banking Provider (Contracting Awards); Innovative Product of the Year (Growth Finance Awards) and we’re listed in the Top 100 FinTech Disruptors and The Startups 100. And that’s just for 2019.
