Job description



👉 Why Happy Team:


Our team consists of experienced programmers open to teamwork and exchange of experiences, which makes us mutually motivate each other for further development. We work fully remotely, at any time.

 

The name of our company (Happy Team) clearly indicates our work culture and the main goals we set for ourselves - we strive to ensure that our employees are satisfied both with their work and with life in general. We achieve this thanks to:

As a Software Engineer, you will contribute to building a lending management solution designed to streamline the client’s various systems and databases. The initial focus will be on creating an API layer to integrate and manage internal systems, followed by the development of a client-facing portal.

🔹 Solid knowledge of Entity Framework Core and relational databases (SQL Server / PostgreSQL)

🔹 Good understanding of UI/UX best practices (responsive design, accessibility, unit testing with Jasmine/Karma)

🔹 Practical experience with AWS services

🔹 Experience with CI/CD pipelines (GitHub Actions, GitLab CI, or AWS CodePipeline)

🔹 Familiarity with monitoring and logging tools (CloudWatch, ELK, Serilog)

🔹 Writing unit and integration tests (xUnit, NUnit, Jest, Cypress)

🔹 Experience with Docker (Kubernetes basics would be a plus)

🔹 Strong understanding of Git

🔹 Experience with software architecture patterns (Clean Architecture, Microservices)

🔹 Integrations with third-party systems (CRM, scoring engines, payment gateways)

🔹 Familiarity with Event-Driven Architecture (Kafka, SQS, SNS)

🔹 Ability to work independently and make technical decisions

🔹 Strong communication skills in English (B2 or higher) to collaborate with international teams

🔹 Openness to feedback and teamwork in a team extension model

🔹 Proactive mindset, eager to improve processes and propose solutions

🔹 Nice to have - background in FinTech, Banking, or Insurance


👉 What we offer:

🔹 flexible and fully-remote job,

🔹 B2B contract,

🔹 health insurance,

🔹 English lessons,

🔹 happy initiatives, e.g. birthday fundraiser for the charity of your choice,

🔹 financial bonus for first-time parents,

🔹 funds for office space rental where you live,

🔹 Multisport card,

🔹 monthly workshops that develop technical or soft skills,

🔹 training budget and space for knowledge-sharing,
