Our product is a secure communication solution for boardroom collaboration, enabling real-time messaging across platforms. We are initiating a full rewrite of the application from the ground up. While the new version is in development, the existing legacy solution will remain live—requiring active support, bug fixes, and minor feature improvements.

This role will be a key engineering contributor—expected to lead and execute across backend, frontend, and DevOps layers. You will take full ownership of the system’s codebase and operations as a self-sufficient engineer.

Ensure secure, scalable, and high-performance delivery across services
Lead development of the new Boards Messenger application from scratch
Maintain, debug, and extend the current production application
Independently manage and deliver new features, enhancements, and patches
Refactor and modernize existing code while improving developer experience
Design, implement, and document backend APIs and microservices
Own CI/CD pipeline automation and containerized deployments
Work closely with the Tech Lead, Product Owner, and platform teams—but operate largely autonomously

Requirements

6+ years in software engineering with proven backend-heavy fullstack experience
Strong expertise in Node.js / TypeScript
Experience in CI/CD workflows using Docker, Kubernetes, GitHub Actions
Confidence operating as a solo engineer on critical systems
Familiarity with microservices architecture, messaging queues, distributed systems
Hands-on experience with database technologies (e.g., MariaDB, Redis)

Preferred / Nice To Have

Proficiency in C# / .NET Core 3.1
Experience with Fastify or ASP.NET Core frameworks
Exposure to message brokers like RabbitMQ, and real-time communication via Socket.io
Familiarity with tools like Grafana, Elastic APM, Postman, and Swagger
