DevOps / Platform Reliability Engineer

About us

House of Biryan (Prosperous Brands Pvt Ltd) is a fast-growing, delivery-first biryani brand  around 30 cloud kitchens across India and 6 in Dubai, selling through Zomato, Swiggy and the Gulf aggregators. The business runs on OPX, our in-house operations platform: attendance, rosters, inventory and stock, store maintenance, complaints, assets, HRM and a live command centre  integrated with Rista POS, delivery-platform data and in-store IoT telemetry.

OPX is entering a major modernize-and-scale phase as the brand expands across geographies. We are hiring its founding full-time engineering team a small crew of 2–3 engineers who will run, build and scale the platform end-to-end. You will ramp up through a structured hand-over with real tasks alongside the current engineering transition team, and then own the platform outright.

The role

You own the ground OPX stands on: a small self-hosted cloud estate (DigitalOcean) running a revenue-critical platform for a 24×7 restaurant business web/app servers, MariaDB, an IoT telemetry pipeline, nightly off-site backups and a young monitoring layer. Your job: make it boringly reliable, then make it scale.

You will

•    Own the infrastructure end-to-end: provisioning, cloud firewalls, TLS and virtual hosts, capacity planning (disk, memory, worker pools), cost awareness, snapshots and rollback discipline.

•    Replace legacy FTP deployments with git-based CI/CD staging to production with rollbacks and per-user accountability and keep it healthy.

•    Run backup and disaster recovery properly: automated nightly database dumps, off-site retention, and scheduled restore drills a backup that has never been restored does not exist.

•    Build out observability: uptime and data-freshness alerting, log rotation and review, response-time logging and dashboards; operate and extend our Python-based alerting service.

•    Lead incident response: triage peak-hour degradations (worker exhaustion, slow endpoints, disk pressure), write the runbook afterwards, and drive recurrences to zero.

•    Partner with the platform lead on the scale roadmap: managed database split, real production/staging separation, object storage and CDN for media, patch and reboot cadence.

Must have

•    3+ years operating production Linux: systemd, networking, firewalls, and web/app servers (Apache or Nginx, PHP-FPM or an equivalent application runtime).

•    A cloud provider in production (DigitalOcean, AWS or GCP): compute, firewalls, object storage, DNS.

•    Built or owned a CI/CD pipeline with rollback for a live product.

•    Backup and restore experience you can walk through concretely tooling, retention, and an actual restore you ran.

•    Monitoring and alerting you set up yourself (any stack), plus scripting fluency in Python and Bash.

•    MySQL/MariaDB operations basics: dumps and restores, slow-query logs, disk and space behaviour.

Nice to have

•    Infrastructure-as-code; MQTT/IoT plumbing; container experience (we are pre-container you would shape that transition).

•    Security-hardening habits; small-company on-call experience.
