It today plays an essential role in connecting banks, businesses, retail merchants, and consumers by enabling commerce in a convenient and secured environment. businesses include Cash Logistics, Banking Automation, Managed Services, Remote Monitoring Solution and Technology Solutions. With 25,000+ employees & third party personnel, servicing 150,000+ business commerce points across 97% Indian districts, it is today a market leader in Cash Logistics, ATM Software Solutions and AIoT Remote Monitoring (Banking segment) businesses. enables financial inclusion by providing access to formal banking services and enabling seamless physical payments for Indians.An Ideal Candidate:Core Technical Skills (Must-Have)  Real-Time Media: Deep expertise in WebRTC (SDP, ICE, STUN/TURN, DTLS-SRTP), HLS/LL-HLS, CMAF, RTP/RTCP, and adaptive bitrate logic.  Media Servers & Tooling: Proven work with at least one of MediaMTX / GStreamer / media soup / Janus / Nimble or equivalents; fluent with FFmpeg for ingest, transcode, and packaging.  Backend Engineering: 4 + yrs. professional Node.js/Typescript (or Go/Rust) building high-throughput Web Socket services; solid async design patterns and memory-profiling skills.  Edge Computing: Hands-on with Raspberry Pi or other ARM SBCs; Linux kernel tuning, hardware-accelerated encoders (MMAL/VAAPI/V4L2).  Networking: In-depth understanding of NAT traversal, UDP vs TCP trade-offs, QoS, TLS termination, load balancing (e.g., NGINX, HAProxy), and CDN principles.  Cloud & DevOps: AWS/GCP/Azure fundamentals (EC2, VPC, IAM, Route 53/Cloud DNS, ELB/ALB), Docker, Kubernetes, Helm, Terraform, GitHub Actions/GitLab CI.  Observability & Ops: Prometheus/Grafana, Loki or ELK stack, distributed tracing (Open Telemetry/Jaeger); capacity planning and auto scaling strategies.  Security: TLS, OAuth2 / OIDC, JWT, WAF basics, CVE triage, CIS benchmarks. Desirable Skills (Nice to Have)  Experience implementing DVR style seek on top of LL HLS or fMP4 fragmented WebRTC recordings.  Prior work on large multi camera surveillance or IoT video platforms (
1 k streams).  Knowledge of Typescript based Web video players (HLS.js, Shaka, Video.js) and MSE/EME.  Familiarity with GPU accelerated computer vision pipelines (OpenCV, TensorRT, DeepStream).  Exposure to message bus architectures (Kafka, NATS) for event fan out and analytics.Key Competencies:Area What You'll Do Architecture & Design  Design end-to-end streaming workflows (edge ingest → cloud signalling/transcode → browser playback) that minimise latency while enabling timeline-scrubbing playback.  Select and tune codecs, segment sizes, GOP structures, and caching strategies appropriate for low-bandwidth or high-jitter links.  Define and document scalable deployment topologies (single-tenant ⇒ multi-tenant, active-active clusters, CDN fan-out). Implementation & Optimisation  Enhance and harden the Node-based signalling layer for high concurrency (WS load balancing, sticky sessions, horizontal sharding).  Optimise media-router configuration (e.g., WebRTC
--
HLS bridges) for adaptive bitrate, trickle-ICE limits, and STUN/TURN fall-back.  Implement scrubbing / seek support by coordinating DVR-side RTSP Range requests with LL-HLS/CMAF generation. Edge Device Management  Automate provisioning and updates for ARM/Linux gateways, ensuring hardware-accelerated encoding and automatic recovery on power loss.  Instrument and monitor edge nodes (health, FPS, temperature, network QoS). Cloud & DevOps  Containerise services (Docker) and orchestrate with Kubernetes (or Nomad / ECS).  Build CI/CD pipelines, IaC (Terraform, Helm) and blue-green / canary roll-outs.  Set up observability stack (Prometheus, Grafana, Loki/ELK) and SLA dashboards. Area What You'll Do Security & Compliance  Enforce encryption in transit (DTLS-SRTP, HTTPS, WSS), authentication (JWT/OAuth), and fine-grained authorisation for publish/read/playback APIs.  Conduct threat modelling and implement rate-limiting, firewall rules, and certificate automation. Leadership & Collaboration  Translate product use-cases into engineering roadmaps; estimate effort and risk.  Mentor developers, run design reviews, and champion coding best-practices.  Liaise with front-end, mobile, and QA teams to debug E2E media issues.
