Role Description

This is a full-time remote role for a Node.js Backend + DevOps Manager at Block-Stars Pvt. Ltd. The role involves day-to-day tasks such as software development, test automation, integration, continuous integration, and infrastructure management.

Responsibilities

Lead a backend team of 5–6 developers (Node.js) and collaborate with 1–2 frontend engineers (India/Sri Lanka team)
Own and drive refactoring of legacy Node.js codebases across both the casino platform and aggregator layer
Take full responsibility for 24/7 system monitoring and urgent issue resolution during on-call shifts
Handle Redis TTL-related issues, transaction mismatch bugs, and racing condition scenarios
Actively participate in critical issue response, including night-time alerts when necessary
Guide overall system architecture, propose tech upgrades, and identify weak points before failures occur
Work with Jira, GitLab, and Slack for structured engineering workflows
Coordinate with DevOps engineers, provide infrastructure direction (Docker/K8s), and ensure proper monitoring (Prometheus, Telegram, Zabbix)
Manage and lead the DevOps team – while not handling day-to-day infra work, you are responsible for strategic guidance and quality assurance on all deployment and infra-related topics

Required Skills & Experience

5+ years of backend engineering experience, including recent technical leadership or EM-level responsibility
Advanced proficiency in Node.js, with the ability to read, refactor, and build scalable systems
Experience with Redis, especially in dealing with TTL, queue-based processing, and concurrency handling
Familiarity with both PostgreSQL and MongoDB (preferably hands-on experience with both)
Solid understanding of Docker and Kubernetes – ability to provide architectural guidance in containerized environments
Prior experience with real-time systems, preferably in payment, fintech, or transactional systems (iGaming experience not required)
Experience coordinating with 24/7 ops or on-call teams
Strong ownership mindset – "see fire, put it out" attitude

Work & Environment

100% Remote (team located across India, Sri Lanka, and Korea)
Tools: Jira, GitLab, Slack, Telegram (alerting), Prometheus, Zabbix
24/7 production system — on-call availability for urgent issue response is expected
DevOps engineers are assigned — you will lead and coordinate them for infrastructure execution
English fluency not strictly required — ability to understand tasks and document clearly is sufficient
