Descrição da oferta de emprego

Описание:

TuxCare provides security solutions for Linux and open-source software used by enterprise organisations. Our products help companies automate vulnerability patching, reduce downtime, maintain security and compliance, and support critical systems throughout their lifecycle. We are looking for a Platform Engineer to join our Platform Engineering team within the Endless Lifecycle Support (ELS) department. ELS helps organisations continue using end-of-life Linux distributions, programming language runtimes, and frameworks securely, even after they stop receiving standard security updates.

Задачи:

• Owning the CI/CD and QA platforms of the department end to end, from hardware and infrastructure through CI runners, build and test environments up to developer experience.
• Being accountable for the platforms' reliability, quality, scalability and cost.
• Analysing how the CI fleet and the services around it are actually used, and turning the findings into data-driven capacity, sizing and performance decisions.
• Improving and automating the tools teams use to build, test and ship, and removing recurring sources of manual work such as flaky tests.
• Contributing to the platform architecture together with engineering teams.
• Maintaining service health with monitoring and runbooks. Alerts are written into the existing company observability tenant.
• Deploying new services following best practices.
• Supporting developer requests and turning recurring ones into self-service.
• Managing incidents end-to-end: diagnosis, mitigation, post-mortems.
• Delivering infrastructure as code through merge-request reviews.
• Writing technical documentation for engineers across teams.
• Working with AI agents: delegating tasks and reviewing their output.

Требования:

• Senior-level infrastructure / SRE experience with ownership of production services.
• Linux systems administration on bare metal and VMs.
• Kubernetes in production: running workloads and clusters, including upgrades and GitOps delivery.
• Infrastructure as code (Ansible, Terraform / Terragrunt).
• Production experience with GitLab CI and CI runners.
• Prometheus/VictoriaMetrics and Grafana, including PromQL.
• Technical writing for engineering audiences.
• Strong communication and interpersonal skills.
• Advanced use of AI engineering assistants such as Claude and Codex.
• Advanced written and spoken English.

Будет плюсом:

• SLO and burn-rate alerting design;
• MicroVM isolation (Kata Containers, Firecracker, gVisor);
• Public Cloud experience, including cost optimisation;
• Self-hosted monitoring systems under load;
• Python or Go for tooling;
• GitLab administration

Условия:

• Stay hands-on technically while working on complex, high-impact engineering projects.
• Work on challenging Linux, automation, and cybersecurity problems across mature and newer products.
• Fully remote work with flexible working hours.
• 24 paid vacation days, 10 national holidays, and unlimited sick leave.
• Private medical insurance compensation.
• Co-working and gym/sports reimbursement.
• Education budget.
• Opportunity to receive a reward for innovative ideas that the company can patent.
