Key Responsibilities:

Designing, building, and maintaining backend services for the Imunify360 server platform;
Developing and improving high-throughput, fault-tolerant messaging and data processing pipelines;
Operating and maintaining core server components, including proxies, message brokers, caches, and databases;
Investigating and resolving complex issues in distributed systems, ensuring uptime and reliability;
Writing and maintaining unit/integration tests to ensure robust, maintainable code;
Collaborating with Infrastructure, Monitoring, and other product teams to refine architecture and optimize system performance;
Monitoring production services using Grafana, Telegraf, and related tooling, proactively addressing bottlenecks and scaling challenges;
Improving CI/CD pipelines for automated, efficient deployments;
Participating in design reviews, incident analysis, and contributing to the long-term technical vision of the team.

Requirements

To thrive in this role, you should have:

5+ years of professional experience as a Backend Developer;
Experience with high-load applications. We are about 100k rps.
Strong proficiency in Golang as the primary development language (including hands-on experience with goroutines), and practical experience with Python, including asyncio-based development;
Experience in maintaining Linux services and web applications on Linux machines;
Experience with AI engineering: LLM, RAG, cost optimization techniques, prompt engineering, etc.;
Hands-on experience with distributed systems and messaging frameworks such as RabbitMQ, Kafka (or similar);
Experience with MongoDB and Redis (including distributed caching and local RPC use cases);
Familiarity with ClickHouse (or other columnar databases) for large-scale analytics;
Practical experience with Docker for local development and productio, n environments;
Experience with HAProxy or similar load balancing/proxy solutions;
Strong understanding of high-throughput service design and distributed system challenges;
Familiarity with CI/CD pipelines, version control (Git), and automated deployment workflows. Experience creating those pipelines from the scratch would be ideal;
Excellent debugging skills, with the ability to deep-dive into network, data, and system-level issues;
Strong communication and collaboration skills, comfortable working in a distributed team;
At least upper-intermediate proficiency in spoken and written English.

Nice to have:

Experience with configuration management systems (e.g., Ansible, Puppet, Salt);
Experience working with monitoring and metrics stacks (Grafana, Mimir, Graphite, Telegraf);
Experience with DNS systems (Unbound or similar).

We value developers who are:

Curious and fearless problem solvers – not afraid to dig into existing systems, investigate root causes, and propose improvements;
Pragmatic and detail-oriented – focused on building reliable, maintainable systems;
Team players – comfortable collaborating in a distributed team environment and contributing to a shared mission;
Effective communicators – able to articulate ideas clearly, exchange feedback constructively, and foster collaboration across teams;
Engaging and proactive – contributing energy, initiative, and a positive presence that strengthens team culture.

Benefits

What's in it for you?

A strong focus on professional development with opportunities for learning and growth:
- Interesting and challenging projects,
- Mentor and other knowledge-exchange programs;
Fully remote work with flexible working hours, that allows you to schedule your day and work from any location worldwide;
Paid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leaves to ensure you maintain a healthy work-life balance;
