Position Overview:
Keepa is a fast-growing BNPL and financial services provider delivering real impact to thousands of clients. This is an opportunity to take ownership of critical backend systems built on a mature .NET Framework and SQL Server—an environment that supports large-scale, real-world financial operations.
You’ll help enhance, maintain, and gradually modernize a robust production platform serving thousands of transactions daily.
We’re looking for developers who are not only technically skilled but also systematic thinkers, proactive problem solvers, and strong communicators—people who take responsibility from start to finish and thrive in collaborative, high-impact environments.

Responsibilities:
Design, develop, and maintain backend services and APIs within an established .NET Framework and SQL Server environment.

Write and optimize stored procedures and complex SQL queries to ensure high performance and reliability across financial transactions.

Collaborate closely with Product, QA, and Operations teams to translate business needs into scalable technical solutions.

Take end-to-end ownership of assigned tasks—from requirement clarification to deployment—ensuring accountability, clarity, and quality.

Participate in the gradual modernization of legacy systems, contributing to architectural discussions and migration planning.

Apply systematic and critical thinking to analyze problems, identify root causes, and propose sustainable solutions.

Demonstrate resilience and adaptability in a fast-moving environment where reliability and precision are critical.

Have experience with structured logging and observability using Serilog, Elasticsearch, and Prometheus, ensuring every financial transaction is traceable and production issues can be diagnosed quickly.

Design and apply caching strategies with Redis to improve performance and reduce database load in high-volume transactional flows.

Requirements:
Strong proficiency in C# and .NET Framework development.
Solid understanding of software design principles (OOP, SOLID, Clean Architecture).
Proven experience developing Web APIs and RESTful services.
Hands-on experience with SQL Server, including stored procedures, indexing, and query optimization.
Familiarity with version control (Git) and Agile/Scrum development practices.
Experience working in data-driven architectures supporting real-world financial or transactional systems.
Strong ownership mentality—you see tasks through and take responsibility for outcomes.
Clear, proactive communicator who collaborates effectively across teams.
Systematic and critical thinker with a structured approach to problem-solving.
Design thinking mindset—ability to empathize with users and create sustainable, user-centered solutions.
Resilient and adaptable when facing ambiguity or complex legacy systems.
Highly self-motivated, organized, and comfortable balancing priorities in a fast-paced environment.

Nice to Have
Experience with older .NET technologies (e.g., .NET Framework MVC, Web Forms).
Exposure to BNPL, Fintech, or other high-volume financial service domains.
Experience with Unit Testing, Integration Testing, and CI/CD pipelines.
