About the Role

We’re on the hunt for a Senior Software Engineer who loves solving hard problems, scaling real-time systems, and building rock-solid infrastructure. You’ll be part of a small, ambitious team shaping the core of our distributed backend — powering real-time communication at scale.If you’re someone who thrives in fast-paced environments, enjoys full ownership of what you build, and gets excited about optimizing performance down to the metal — we’d love to talk.

Design and build scalable backend services in Node.js and Python.
Power real-time communication using WebSockets, RabbitMQ, and event-driven architectures.
Architect and scale distributed systems that stay fast and reliable under heavy load.
Deploy, monitor, and tune systems on AWS with Docker and Linux.
Work hands-on with PostgreSQL for high-performance data modeling and querying.
Collaborate closely with product, ops, sales teams to bring new features to life.
Own your work — from design to production rollout.
(Bonus) Lead, mentor, and inspire junior engineers as the team grows.

Job Requirements

What We’re Looking For

3+ years of experience building production-grade backend systems.
Strong command of Node.js, Python, and RESTful or event-based APIs.
Hands-on experience with WebSockets, RabbitMQ, and AWS.
Deep understanding of PostgreSQL, Docker, and Linux systems.
Experience designing and scaling distributed systems.
A passion for clean architecture, automation, and performance.

Nice to Have

Experience with Go (Golang).
Exposure to VoIP protocols like SIP or RTP, or experience with real-time voice/video/SMS systems.
Experience building or scaling real-time communication platforms.
Leadership chops — you love helping others level up.

Why You’ll Love Working Here

Work on cutting-edge real-time systems that actually scale.
High-impact role — your code will be powering production from day one.
Tight-knit, highly technical team that moves fast and ships often.
Freedom to explore, experiment, and own entire parts of the stack.
Room to grow into architecture and leadership roles as we scale.
