About Us
Duco is on a mission to reduce the time spent on data-related work by 90%. Our enterprise data automation platform empowers teams to work more efficiently and meaningfully by giving them the ability to automate data controls with the latest technology, such as no-code, the cloud, and AI.
We help firms to start trusting their data, by giving them one intuitive platform to automate the front-to-back processing of all kinds of data (from structured Excels and RTFs to unstructured PDFs and emails). This eliminates the boring manual work across the data lifecycle and enables firms to act faster, work smarter, save money, reduce risk and comply with regulatory requirements.
We’re headquartered in London and have offices in New York, Wroclaw, Singapore, and Antwerp. We’re proud to call some of the largest global financial institutions our clients, including over 15 of the world’s largest international banks, as well as brokers, exchanges, asset managers, hedge funds, administrators, service providers and corporates.
The Opportunity
At Duco, we are hiring a Senior QA Engineer to join our Agentic Operations team. The team is changing how clients use the Duco platform. Users can already run their operations through an AI agent: they ask it to create a process, or to explain why an exception came out of one. Next, we are making the whole platform agentic.
In this high-impact position, you will own the quality of releases across our two main products: our AI agent workspace and the core Duco platform. You will work across Engineering teams in London, Antwerp and Poland to run risk-based release regression, test AI-agent features end to end, shape our test strategy and give a clear go/no-go recommendation for every release.
What You’ll Own
- Lead regression testing for weekly and monthly releases. You’ll work out what changed from Jira and git, prioritise scenarios by risk, run them, report the results and give a go/no-go recommendation.
- Test AI-agent features end to end on our QA clusters, including tool calls, human-in-the-loop approvals, streaming, and failure and retry paths.
- Define the test strategy: what is covered by unit, integration and end-to-end tests, what is tested by hand, and what goes into regression, adjusted using release data.
- Write and debug Playwright tests, and triage end-to-end failures in CI.
- Maintain our AI-assisted testing tools and scenario library, and introduce new practices safely within InfoSec’s conditions.
- Review tickets for testability and acceptance criteria before development, review test code merge requests, and raise actionable bugs with the right severity.
What You’ll Bring
Ideally, you’ll have
- Proven experience in QA or SDET roles, including at least 2 years testing releases of a production SaaS product.
- Experience running end-to-end release regression with little supervision, from scoping and planning to a go/no-go recommendation.
- Strong risk-based test design: you decide what to test first, and what not to test when time is short, and can defend that call.
- Proven test automation in a modern framework (Playwright preferred), with fluency in Python or TypeScript and the ability to read a merge request in Python, Ruby, Java or TypeScript.
- Confident SQL, plus experience investigating issues with logs, metrics and basic Kubernetes (kubectl).
- Everyday use of Jira, GitLab merge requests and CI pipelines, and comfort on the command line.
- Clear written and verbal English, and the confidence to align several teams on scope and release readiness.
Bonus points if you also have
- Hands-on experience testing LLM or agent products (tool calls, human-in-the-loop approvals, streaming).
- Experience using Claude Code or similar AI coding assistants for testing work.
- Performance and load testing experience.
- Experience with Java-based UI and API test suites (Selenium, RestAssured), GitOps release workflows or AWS.
- A background in financial services data such as reconciliation, payments or trade processing.
