Product documentation:

We’re seeking a Principal Engineer who combines hands‑on execution with product ownership for automation tools. You’ll build services and automation while owning the roadmap for patch‑processing tooling, prioritizing by impact, risk, and effort. You’ll partner with engineering and operations stakeholders to turn business needs into shippable deliverables and measurable outcomes.

• Write production Python code (services, CLI tools, automation)
• Build and maintain CI/CD on Git Lab
• Prototype quickly and turn successful experiments into production‑ready solutions
• Improve reliability and operability (logging, metrics, monitoring/alerting)

• Actively use modern AI tools daily to accelerate coding, refactoring, debugging, testing, and documentation — while validating outputs, catching edge cases, and shipping production‑quality code.

• Own the vision and roadmap for ELS Automation tools; prioritize by impact/risk/effort
• Translate business needs into deliverables (plans, user stories, acceptance criteria, success metrics)
• Be the primary stakeholder interface: align requirements across engineering/release/ops and communicate trade‑offs
• Drive outcomes: incident coordination when needed, post‑mortems, and continuous improvements

• 8+ years in software engineering, with recent daily Python coding
• Strong Git Lab CI / Git Hub workflows (runners, pipelines)
• Solid Linux fundamentals (shell, processes, networking, packaging)
• Comfortable with observability (logs, metrics, monitoring, alerting)
• Advanced use of LLM/AI tools to speed up coding, refactoring, debugging and tests, and validates outputs to production quality
• Product ownership mindset: can own a tool end‑to‑end, build/prioritize a roadmap, and translate ambiguous requirements into deliverables
• Comfortable working in a fast‑changing, high‑ambiguity environment; able to iterate quickly and adapt priorities
• Startup and/or “builder” experience: has shipped own projects or worked in a startup‑like setting with end‑to‑end responsibility
• Strong English communication with both technical and non‑technical stakeholders

• A focus on professional development.
• Interesting and challenging projects.
• Fully remote work with flexible working hours, that allows you to schedule your day and work from any location worldwide.
• Paid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leaves.
• Compensation for private medical insurance.
• Co‑working and gym/sports reimbursement.
• Budget for education.
• The opportunity to receive a reward for the most innovative idea that the company can patent.
