Backend Engineer

About Kirrhosoft

Kirrhosoft is a startup founded by a veteran software engineer who, after working for decades in multiple countries, moved back to Bangladesh with a dream: to bring about changes that were missing in the local industry.

In that line, we are a company that embraces modern and international culture to foster creativity, collaboration, and innovation. We provide an exciting environment for professionals who crave challenges and continuous learning.

Implement secure data handling, input validation, and error management practices.
Work closely with frontend engineers to design and document clean API contracts.
Integrate third-party services, APIs, and tools as required by product needs.
Participate in code reviews, both giving and receiving constructive feedback.
Communicate clearly on progress, blockers, and technical tradeoffs with the team.
Write unit and integration tests to ensure reliability and catch regressions early.
Support basic DevOps tasks such as deployments, environment configs, and monitoring in collaboration with the team.
Maintain and improve existing codebases with an eye for technical debt reduction.
