Full Stack Engineer

We Look For Character Over Credentials

• We’re a specialist financial technology company transforming B2B credit (website) 
• We’re backed by top European and American VCs including Dawn Capital, Octopus Ventures, Talis and Expa 
• Founded in 2020, we are licensed and operating across the UK, Europe, US and Canada with offices in London, New York and Dallas 
• Since our commercial launch in March 2022, we are already serving some of the world’s largest companies, providing them with superior credit protection and innovative risk management technology 

About The Role We’re looking for a Full Stack / Back End Engineer who’s excited to build reliable systems and experiment with new technologies. You’ll help design, build, and maintain the APIs and services behind our platform, working across the stack from infrastructure to UI. You’ll be closely involved in technical decisions, architecture, and best practices, while contributing directly to the codebase. Beyond core programming skills, we value interest or experience in data, security, or DevOps that help raise the bar across the team. As we expand our use of AI and large language models, you’ll have the chance to work on projects that combine data, automation, and intelligent tooling in real production environments. Above all, we’re looking for a positive, collaborative individual – confident in their skills, focused on outcomes, and able to challenge ideas constructively. Someone who balances productivity with continuous learning and improvement, and who’s willing to both teach and learn from others. You’ll report to one of our Tech Leads and work closely with our product and data teams. As part of a small, high-caliber engineering group, you’ll collaborate across disciplines — gaining exposure to architecture, product development, and data-driven decision-making while contributing to meaningful projects and growing your technical breadth. This is a fantastic opportunity to join one of the most exciting financial technology companies, with the chance to grow and develop alongside the business. Our Approach To Engineering We follow an Agile development methodology - but unlike others, we use a flexible variant of Scrum across the entire organisation, including executive tasks and decisions. Our multidisciplinary team offers flexibility for individuals to move between core engineering, infrastructure, testing and research. Our stack includes Go, VueJS, Postgres and Python, deployed through a fully automated AWS environment (Terraform, Ansible, GitHub Actions). Alongside this, we’re building the next generation of our data and AI infrastructure — exploring frameworks like Hugging Face, LangChain, LlamaIndex and agent orchestration systems. We use Cursor and Copilot to speed iteration and experimentation. We’re always open to new approaches, whether it’s a different data stack, AI toolkit, or a creative way to apply LLMs in production. Responsibilities

• Design and build scalable, maintainable services and APIs that power our core platform.
• Contribute to both frontend and backend development, ensuring seamless integration across the stack.
• Write clean, reliable, and testable code that meets high standards of quality and performance.
• Participate in architectural discussions, helping to shape best practices and technical direction.
• Improve our development workflows, testing frameworks and deployment pipelines
• Monitor and optimise system performance, proactively identifying and resolving bottlenecks.
• Champion code reviews, documentation, and knowledge sharing to raise the technical bar across the team.
• Explore and experiment with emerging technologies, including AI and LLMs, to enhance our products and workflows.
• Contribute to a positive, collaborative engineering culture focused on continuous improvement

You Might Be a Good Fit If

• You have around 2–4 years of professional software engineering experience.
• You’re comfortable with at least one server-side language (Go, Python, or Java).
• You’ve worked with relational databases (Postgres) and are curious about exploring NoSQL systems (MongoDB, Redis, Cassandra).
• You’ve built and consumed RESTful APIs and enjoy thinking about clean service design.
• You’re familiar with modern front-end frameworks (VueJS, React, or Angular).
• You understand Git-based workflows and CI/CD pipelines.
• You have had some exposure to infrastructure or deployment tools (AWS, Terraform, Ansible, Docker, or Kubernetes).
• You write clean, maintainable code and think about how systems fit together end-to-end.
• You’re curious about how AI and LLM tools — such as Cursor, Copilot, or ChatGPT — can make engineering faster, smarter, or more creative.
• You communicate clearly, enjoy collaborating with others, and bring a positive, problem-solving mindset.
• You care about quality, security and scalability in everything you build.
