Company mission
Duco's mission is to make managing data easy.
Role
Who you are
- Experience delivering and supporting resilient software that scales, in a multi-language, multi-technology stack
- Deep experience with Java or another statically-typed language, and familiarity with a web framework (Spring Boot or Ruby on Rails)
- Strong skills in automated testing (unit, end-to-end, performance, stress) and a high bar for quality
- Working knowledge of SQL and relational database concepts at scale, including performance optimisation
- Technical or team leadership experience, with practical experience of service-oriented architectures and container-based deployment (e.g. Kubernetes, Helm)
- A genuine interest in using AI to improve software engineering, with ideas (and ideally hands-on experience) for applying it individually and across a team's pipeline
Desirable
- Solid experience with a dynamically-typed language (e.g. Ruby); JavaScript, TypeScript and a front-end framework (React)
- Aptitude with CI/CD pipelines (GitLab preferred) and cloud computing, preferably AWS
- Experience with harness engineering or integrating AI / LLM-based tooling into a workflow or CI/CD pipeline, or with AI-assisted code review, test generation or developer productivity tooling
- Experience of architectural migration (e.g. service extraction or refactoring) and feeding observability or metrics systems
What the job involves
- You will work in one of our cross-functional, empowered engineering teams
- Each team owns its part of the product and makes decisions jointly, alongside Product, Sales and other customer advocates
- You won't just build what someone else specifies; you will create new solutions to difficult problems and help take the platform to the next level
- As a Senior Engineer, you will be a subject matter expert across multiple areas of the platform, involved in cross-team technical design, and independently responsible for the full lifecycle of the projects you deliver
- At this level we expect your impact to reach beyond your own work: lifting your immediate team, and raising the bar across engineering as a whole through technical leadership, reviews and mentoring
- We also want you to help shape how we build
- AI is already core to our product, and it is changing how we engineer software just as fast
- We want someone with the curiosity and judgement to help us adopt it well, across how the whole team designs, builds, tests and ships
- Deliver features into the core product, across all areas of the technology stack
- Own the full lifecycle of your work: design, development, deployment and ongoing support
- Lead spikes and technical design for work that spans more than one team or domain
- Code review your peers' contributions and give clear, constructive feedback
- Tackle gnarly data manipulation and scaling problems with a team of very bright people
- Mentor engineers and lift capability across the wider engineering function, including in how we use AI

Our take
Enterprises capture and generate a vast amount of business-critical data, but inconsistencies in formating and difficulty in reporting across multiple data silos can make it extremely difficult to actually use this data for operational decision making. Duco exists to solve this problem with a no-code platform to reduce the complexity of a company's data stack, processing, reconciling and drawing insights from data without requiring any special expertise.
Duco's no-code approach, using natural language processing to manage queries, means that decision makers can directly poll data without relying on technical teams or external firms. This leads to cost savings, which have generated a return on investment for Duco's customers in less than a year. So far, Duco's services have been taken up by major firms such as HSBC, Lloyds Bank and Santander, to name just a few.
The company has expanded into Asia and is using investment to further refine the product, allowing it to solve more complex data problems for its clients. As more and more companies realise that there is an easier alternative to reconciling their data than doing it by hand, Duco, having refreshed its leadership in 2026, is in an excellent position to continue its rapid growth.
