We’re looking for a Technical Business Analyst to own the flow of client requests, turn them into clear requirements and bring features from idea to release. You’ll work closely with the product team, clients, engineers, designers and QA, with room to grow in product management.

What you’ll do

• Analyse client requests: find the real need, check how the system works today and whether it already covers the case.
• Run system and impact analysis, propose alternatives and estimate effort when a request can’t be delivered as asked.
• Talk to clients directly: discovery calls, clarifications, demos, validating solutions and collecting feedback.
• Write business and product requirements, break them into epics, user stories and testable acceptance criteria.
• Maintain the backlog, prepare refinements and support engineers and QA when requirements change during development.
• Analyse API documentation, business rules, dependencies and edge cases together with engineers.
• Document flows with BPMN/UML and keep Confluence and client-facing instructions up to date.
• Research the market and competitors for new initiatives and measure the impact of shipped features.

What we’re looking for

• 2+ years as a Business Analyst, System Analyst, Technical Product Owner or similar in a fintech product (payments, banking, acquiring, PSP, billing). A technical background (QA, development, support engineering, data) or equivalent hands-on understanding of how products are built.
• Solid understanding of REST APIs, HTTP, JSON and client-server architecture; practical experience with Swagger/OpenAPI and Postman.
• Experience turning vague requests into structured requirements, user stories and acceptance criteria.
• Practical BPMN/UML, Jira and Confluence; understanding of Agile/Scrum and the SDLC.
• Clear, assertive communication with developers and with demanding clients; ownership of open questions and commitments.
• English B2+ for calls with international clients and readiness to work from our Kyiv office.

Nice to have

• SQL for analysis and validation of feature impact.
• Basic UI/UX understanding and Figma: reading designs, clickable flows, wireframes.
• Experience with subscription-based products or billing.
• Confident use of AI tools (Claude, Codex, etc.) in research and analysis.
• Interest in growing in product management.

What we offer

• Financial Growth & Stability: Competitive fixed gross compensation with full legal and accounting coverage (FOP).
• Highload Product & Ownership: Work on a massive PayTech product with zero bureaucracy, Open Door Policy, Corefy Academy, PDPs, and covered professional certifications.
• Hybrid Work Format: Work from our Kyiv office near KPI metro 3 days a week and remotely 2 days a week. Enjoy a flexible 8-hour schedule, panoramic views, free breakfasts, PlayStation, table tennis, hookahs, power generators, Starlink, and a safe shelter.
• Care & Wellbeing: 20 paid vacation days, 10 sick leave days, official public holidays, free mental health support with psychologists, milestone gifts, and team events.
• Pro Gear: Choose your setup — top-spec MacBook or Linux laptop with all necessary accessories.
