DevOps / Site Reliability Engineer (SRE)

• *Job Title:** DevOps / Site Reliability Engineer (SRE)

• *Location:** Coimbatore, Tamil Nadu (Hybrid/Remote)

• *Job Type:** Full\-time

• *About the Role**

We are looking for a high\-performance DevOps / Site Reliability Engineer (SRE) to own the stability, deployment, and performance scaling of our real\-time, low\-latency meta\-dispatch kernel. Unlike typical cloud\-only roles, this position bridges elite software engineering with bare\-metal Linux infrastructure management.

You will work directly with our core architecture team to ensure our concurrent Go ingestion layers, Python heuristic engines, and real\-time gRPC communication pipelines operate with deterministic microsecond latency. You will design, implement, and maintain the infrastructure that keeps hundreds of high\-throughput mobile and aerial assets synchronized across Country.

• *Key Responsibilities**

• **Infrastructure Ownership:** Configure, optimize, and maintain our enterprise bare\-metal Dell PowerEdge server environment running high\-density Linux host distributions.
• **Kernel \& Network Tuning:** Maximize packet\-processing throughput by implementing advanced Linux system configurations, including CPU core isolation (isolcpus), interrupt affinity, socket re\-use parameters (SO\_REUSEPORT), and 1GB HugePages allocation.
• **SRE Framework Implementation:** Codify the reliability of our network core. Define and monitor precise Service Level Indicators (SLIs) and Service Level Objectives (SLOs) around memory allocation boundaries, network saturation, and gRPC payload latency.
• **CI/CD Pipeline Architecture:** Build and automate robust deployment pipelines that securely compile cross\-platform, statically linked Go binaries and containerized Python workloads.
• **Observability \& Monitoring:** Design and scale high\-fidelity telemetry dashboards monitoring the "Four Golden Signals" (Latency, Traffic, Errors, Saturation) to proactively mitigate performance degradation.
• **Security \& Fail\-safe Engineering:** Implement and maintain mutual TLS (mTLS) cryptographic handshakes across public wireless networks and manage root security permissions within Linux systemd service units.

• *Required Technical Skills**

• **Systems \& Infrastructure:** 3\+ years of experience in Linux System Administration managing dedicated bare\-metal servers (compute sharding, hardware offloading, storage arrays).
• **Programming/Scripting:** Proficiency in Go (Golang) and Python for writing automation scripts, monitoring tools, and understanding low\-level execution paths.
• **Networking Protocols:** Deep understanding of high\-concurrency network architectures, specifically handling low\-level UDP sockets, TCP, gRPC, and protocol buffer serialization.
• **Process Management:** Strong experience deploying, performance\-capping, and securing system services via Linux systemd.
• **Databases:** Hands\-on experience scaling and managing high\-frequency write operations inside MongoDB or PostgreSQL.

• *Preferred Qualifications**

• Familiarity with spatial indexing libraries (specifically the Uber H3 spatial grid system or PostGIS).
• Experience configuring network elements over commercial 5G/LTE cellular backhauls or Machine\-to\-Machine (M2M) SIM communication channels.
• A strong background in blameless post\-mortem operational cultures and automated toil reduction.

• *What We Offer**

• The opportunity to work on a cutting\-edge, high\-impact proprietary kernel platform.
• A tech\-first environment where performance engineering takes priority over boilerplate cloud configuration.
• Competitive compensation and growth opportunities within a fast\-scaling venture.
