We are a pioneer investor in Fintech Lending, enabling Real Economy Impact.

Fasanara manages one of the largest and longest standing Fintech Lending fund in Europe and invests in early-stage Fintech companies via its venture capital vehicles, using its central role in the Fintech ecosystem to identify and back revolutionary new businesses.

The role

Our Tech Team at Fasanara is looking to bring onboard a senior Full-Stack Engineer who will be essential in expanding the capabilities across our investment tools, working on several Greenfield projects. You’ll have the opportunity to partner across multiple business areas building scalable innovative solutions. This role would suit an ambitious, seasoned engineer who wants to be part of an expanding engineering team having a big impact.

Responsibilities

• Design and develop scalable, high-performance internal platforms and applications for core business functions including Credit Trading, FX Hedging, Portfolio Monitoring, and Treasury.

• Collaborate cross-functionally with investment, operations, and data teams to translate complex business workflows into efficient, maintainable software solutions.
• Drive the full software development lifecycle - from technical design and implementation to testing, deployment, and production monitoring.
• Contribute across the stack, including backend services, frontend interfaces, and data engineering pipelines as needed.
• Provide technical leadership and mentorship to more junior team members, fostering a culture of learning, accountability, and continuous improvement.

• A degree in Computer Science, Engineering, or a related technical field, or equivalent hands-on experience in a professional environment.
• Proven experience designing and developing robust APIs, microservices, and backend systems that power business-critical workflows.
• Experience with at least one of the following languages: Go, Python, Java, C#, or C++. We primarily use Go and Python — familiarity with these is a strong advantage.
• Solid knowledge of relational databases and proficiency in SQL (e.g., MySQL).
• Practical experience in modern front-end technologies including TypeScript, React, and CSS.
• Experience architecting solutions using cloud infrastructure, particularly AWS.
• Competency with standard development and collaboration tools (e.g., Git, GitLab, CI/CD workflows).
• Excellent communication and stakeholder management skills; you’re comfortable discussing technical trade-offs with both engineers and non-technical colleagues.
• Bonus: A portfolio, GitHub profile, or examples of personal projects that showcase your technical abilities and creativity.

• Competitive bonus scheme.
• Bupa health & dental, Cycle to Work scheme, enhanced pension, and generous annual leave.
• Enhanced parental leave, special leave allowances, and charity giving options.
