Build, deploy and operate Python services on Linux. The role demands strong Linux fundamentals — including sudo, systemd, shell scripting and permissions — alongside production-grade Python engineering.

Key Responsibilities

Design and develop backend services and automation tooling in Python 3.x.

Build and consume RESTful APIs using FastAPI / Flask / Django.

Operate services on Linux (RHEL / Ubuntu / CentOS); manage users, groups, sudoers and file permissions.

Write robust Bash / shell scripts for deployment, scheduling (cron / systemd timers) and Package, deploy and monitor services using systemd units, journald and standard Linux tooling.

Diagnose production issues using strace, lsof, top, iotop, ss, tcpdump and log analysis.

Collaborate with DevOps on CI/CD, container builds and server hardening.

Must-Have Skills

7+ years of production Python development (3.9+).





Deep understanding of sudo and /etc/sudoers — privilege delegation, NOPASSWD rules, security implications.

Proficient in Bash scripting, cron, logrotate and SSH-based automation.

REST API frameworks: FastAPI, Flask or Django REST Framework.

Oracle database experience — PL/SQL, stored procedures, query tuning; cx_Oracle / oracledb driver and SQLAlchemy ORM.

Virtual environments, pip / poetry, packaging and dependency hygiene.

Git-based workflows and code-review discipline.

Valuable-to-Have Skills

Message brokers — RabbitMQ, Kafka, Redis Streams.

Observability stack — Prometheus, Grafana, ELK.

Async Python (asyncio, aiohttp) and concurrency tuning.

Cloud exposure — AWS or Azure for compute, storage and secrets.
