An innovative fintech environment in Estonia is looking for a Fintech Product Support Engineer to provide technical investigation and operational support for financial technology products used by customers and internal teams.

This is a hands-on technical position for someone who enjoys diagnosing complex issues, analyzing application behavior, working with APIs and databases, and collaborating directly with software engineers and product specialists.

The successful candidate will become an important technical bridge between customers, operations, product teams, and engineering.

Your Responsibilities

• Investigate technical issues affecting fintech applications and financial-service platforms.
• Analyze application logs, API responses, database information, and system behavior.
• Diagnose integration and transaction-processing problems.
• Investigate payment, account, authentication, and application-related incidents.
• Reproduce technical issues and document findings for engineering teams.
• Work with developers to identify root causes and verify fixes.
• Monitor support queues and prioritize issues according to business and customer impact.
• Provide technically accurate responses to operational and customer-facing teams.
• Maintain detailed incident and troubleshooting documentation.
• Assist with API testing and integration troubleshooting.
• Use monitoring and observability tools to investigate system behavior.
• Support testing following software releases and infrastructure changes.
• Identify recurring problems and recommend improvements to product teams.
• Contribute to knowledge bases, technical runbooks, and support procedures.
• Participate in incident reviews and continuous-improvement initiatives.

What You Bring

We are looking for someone with a strong technical foundation and an interest in financial technology.

Relevant experience may include technical support engineering, application support, fintech operations, software development, payment technology, systems administration, or production support.

You should have:

• Strong troubleshooting and diagnostic skills.
• Understanding of REST APIs and web-based applications.
• Familiarity with JSON and structured data.
• Working knowledge of SQL or database concepts.
• Ability to interpret application logs and technical documentation.
• Strong understanding of software-development workflows.
• Excellent written communication.
• Ability to explain technical problems clearly to non-technical stakeholders.
• Strong attention to detail.
• A methodical approach to incident investigation.

Experience with Python, JavaScript, Postman, Git, cloud platforms, monitoring systems, ticketing platforms, Docker, payment APIs, banking integrations, or digital-wallet infrastructure would be beneficial.

Why This Position Matters

Financial technology requires more than software that works during development. It requires reliable systems operating under real-world conditions.

This role places you close to those systems, giving you the opportunity to investigate live technical challenges, collaborate with engineering teams, and contribute to improvements across digital financial products.
