Role Summary

The Software Engineer (Full Stack, Senior) designs, builds, ships and operates major features and microservices end to end across Kallipr’s SaaS platform through the full SDLC. The role is hands on and primarily backend-focused, with frontend contribution where needed. This person builds APIs, shapes domain logic, and implements integrations that support device connectivity, platform services, and customer-facing features.

Kallipr engineers own their software from design through production. You build it, you ship it, you watch it, you fix it. Operational depth — pipelines, monitoring, and production support — is as much a part of this role as writing code.

A Senior Full Stack Engineer defines clear, scalable service workflows and data contracts across frontend, backend, and hardware boundaries, ensuring systems interact reliably and perform well in real-world conditions. They work closely with the embedded engineering team to integrate new devices and account for device behaviour in production. They solve non-trivial technical problems that require investigation, judgment, and sound trade-offs, and they improve system design through practical, maintainable engineering decisions.

The role carries ownership for complex services and major feature architecture within a broader system. Senior Engineers lead design discussions in their domain, make and explain long-term trade-offs across reliability, security, cost, and delivery speed, and strengthen operational health through improvements to observability, resilience, CI/CD, and production support. They raise engineering standards through hands on contribution, mentoring, and cross-team collaboration, helping ensure that adjacent systems connect cleanly and that the platform can scale sustainably.
