Senior Technical Business Analyst - FINTECH / LONDON

At Adaptive, we are a financial consulting firm that partners with capital, commodity, and digital market participants. We value differentiation through technology.

Our experienced teams design and deliver complex front-office technology solutions using our proven accelerators to create long-term competitive advantage.

Our clients include the world's leading investment banks, investment managers, fintechs and capital market service providers.

With a global reach with offices in London, New York, Manila, Barcelona and Montreal, we have a proven track record of delivering powerful, elegant and intuitive trading technology solutions.

We are now looking for a Technical Business Analyst to join our team — someone who can bridge the gap between high-level product vision and detailed delivery execution in a complex, fast-moving technical environment.

If you feel like this is you, you might be a perfect fit for this role! 🎉

• A strategic thinker who can zoom out to understand the big picture and zoom in to nail the details.
• A natural bridge-builder — equally comfortable in a room full of engineers and a room full of stakeholders.
• A problem-solver who thrives in ambiguity and brings calm, clarity, and structure to complex situations.
• A curious mind who genuinely enjoys understanding how systems work, not just what they need to do.
• A collaborative team player who believes the best solutions come from diverse perspectives.

• A strong technical and domain-driven mindset, with the ability to work closely with engineering teams.
• Knowledge of distributed systems, system interactions, and concepts such as state machine replication.
• Experience in QA, Software Engineering, Technical Business Analysis, or another highly technical product environment.
• A product-first mindset, combining Domain-Driven Design principles with a deep understanding of systems and user impact.
• The ability to define and document functional and non-functional requirements clearly and effectively.
• An understanding of performance, scalability, resilience, and availability in modern platforms.
• Experience working in Agile or Kanban environments across the full software development lifecycle.
• Confidence contributing to architecture and design discussions, simplifying complex challenges into deliverable solutions.
• The ability to create process flows, sequencing diagrams, and documentation that align technical and operational teams.

• Operate confidently in ambiguous situations, shaping requirements and driving alignment with minimal direction.
• Adapt to different delivery models across products, including engineering-led and BA-led ways of working.
• Define and maintain functional and non-functional requirements — including operational scenarios, acceptance criteria, and QA validation needs across distributed workflows
• Ask the right questions early, so that solutions are well understood, well defined, and ready to be delivered.

• Collaborate with engineering, QA, and architecture teams to translate complex technical solutions into structured backlog items, deliverable stories, and testable outcomes.
• Help stakeholders make their vision for the product materialise, especially in the early stages of each delivery phase.
• Be the stakeholders' proxy in the team — able to make quick, firm decisions on scope, requirements and prioritisation/triage.
• Drive backlog review and estimation processes, and take part in planning activities.
• Define acceptance criteria and tests up front as part of a Business-Driven Development approach.
• Follow up during implementation and testing phases to ensure delivery satisfies requirements.

• Work closely with QA to assess failure scenarios and help distinguish bugs, enhancements, and new feature requirements.
• Facilitate discussions across technical and business stakeholders to drive clarity, alignment, and sound decision-making.
• Support delivery, implementation, and release processes, ensuring solutions align with business objectives, customer use cases, and non-functional expectations.
• Help improve operational processes and workflows — both internally and externally — bringing a calm, pragmatic and collaborative approach.

• To be immersed in high-standard engineering culture.

THE PROCESS

Long interview processes are stressful and boring, and that is not us 😉

We want to make sure that everything runs smoothly.

So here you will have three stage interviews:

1- A chat with one of our great recruiters.
2- A zoom chat with one of our BA colleagues where they will ask you detailed questions about your experience
3- A Face to Face interview (via Zoom).

But don’t worry; everything will be explained to you step by step by your recruiter. 

Here is a little tip for you during those stages: 

Collaboration is massively important to us, so don't hesitate to share your thoughts, ask questions, ask for help if needed, etc 😊

Diversity and inclusion are key to a great workplace, and Adaptive is better when it’s more representative of the world around us. We want everyone to feel comfortable bringing their whole selves to work without any fear of judgment or negativity. 

All we ask is that our colleagues are respectful, collaborative, passionate about what they do, and have the skills needed to be successful in their roles
