Senior DevOps/SRE Engineer

We are looking for a Senior DevOps/SRE Engineer to join an existing high‑performing platform team and enhance the reliability, scalability, and performance of a large AWS‑based ecosystem. This role focuses on Infrastructure as Code, CI/CD, Observability, and operational excellence while supporting upcoming platform changes/migrations. The position is senior‑level but does not include leadership or team‑management responsibilities.

Requirements:

Must‑Have:

• Expert knowledge of AWS services and modern architecture patterns (Kinesis, DynamoDB, Lambda, SQS, SNS, RDS, ECS, EKS, etc.).
• Advanced Infrastructure‑as‑Code experience using Terraform.
• Strong CI/CD expertise (preferably GitHub Actions; others acceptable).
• Solid Linux/Unix administration background.
• Strong security, compliance, and access‑management understanding.
• Observability & monitoring expertise—Grafana stack preferred (incident management, synthetic checks, performance dashboards).
• Experience defining and tracking SLOs, SLIs, and Error Budgets.
• Experience working in multi‑account AWS organizations.
• Strong troubleshooting and problem‑solving skills.
• Excellent communication skills and ability to work effectively in a collaborative environment.
• Continuous learning mindset and ability to adapt to new tools and technologies.
• At least Upper Intermediate English level.

Nice‑to‑Have:

• Hands‑on programming (Go/Python/TypeScript) — not required, but beneficial.
• Workload migration experience (e.g., EKS → ECS + Lambda).
• AWS Professional‑level certifications.
• Experience with multi‑cloud environments or cloud cost‑optimization strategies.
• Background in performance & capacity engineering.

Responsibilities:

• Design, maintain, and optimize AWS cloud infrastructure using Terraform and best‑practice IaC patterns.
• Implement, operate, and evolve CI/CD pipelines for reliable and fast delivery.
• Improve system reliability through SRE practices: SLOs, error budgets, incident reviews, and root‑cause analysis.
• Drive observability: build dashboards, alerts, synthetic checks, and incident workflows using Grafana (and/or Datadog).
• Support and collaborate on upcoming migrations (e.g., from EKS to ECS + Lambda).
• Ensure security, compliance, and proper IAM governance across multi‑account environments.
• Contribute to performance tuning, capacity planning, and cost awareness efforts.
• Troubleshoot production issues, participate in incident processes, and reduce MTTR through automation.
• Collaborate with engineers, product teams, and a Principal DevOps/SRE engineer to improve operational maturity.
• Maintain documentation, share knowledge, and help raise engineering standards across the team.

What we offer:

• Annual paid vacation of 18 working days.
• Extra vacation days for long-lasting cooperation.
• Annual paid sick leave of 10 days.
• Maternity/Paternity leave.
• The opportunity for sabbatical leave.
• Marriage and Parenthood Package.

• Career development plan.
• English and Spanish classes.
• Paying taxes and managing PE (Private Entrepreneur).
• Technical equipment.
• Internal Referral program.
• Opportunity to take part in company volunteering activities.
• Sombra is a “Friendly to Veterans” award-holder.
