Descripción de la vacante

Dempo is seeking a Senior SRE Engineer to lead reliability efforts across production systems in a remote-first culture with an option to work from the Granada office. You will drive observability, incident response leadership, and architectural decisions for reliability-critical services.

You will mentor cloud/platform engineers, define SLIs/SLOs, and contribute to CI/CD improvements while balancing speed, quality, and long-term resilience in a multinational tech environment.

Formación

• 5+ years of experience in SRE, Cloud, or Platform engineering roles.
• Profound knowledge of SRE principles and incident response practices.
• Profound knowledge of the observability stack: logs, metrics, traces, and distributed tracing.
• Profound knowledge of Kubernetes cluster operations and workload objects.
• Solid networking fundamentals: DNS, TLS, load balancing.
• Hands-on experience with Infrastructure as Code (Terraform or equivalent).
• Scripting proficiency (Bash or Python) for tooling and automation.
• Strong Git and collaborative workflow experience.

Responsabilidades

• Lead incidents as commander and manage severity, with rapid mitigation and diagnosis.
• Own the incident record and timeline, linking deployments and incidents.
• Communicate with stakeholders during active incidents.
• Conduct blameless postmortems and drive toil identification and elimination.
• Implement observability pillars (logs, metrics, traces) end to end.
• Define SLIs and SLOs for critical services and design alerting systems.

Descripción del empleo

We are looking for a Senior SRE Engineer to join our infrastructure team and take technical leadership over production resilience. This role sits at the Senior level on our Cloud/Platform/SRE career path — reliability engineering with a heavy focus on metrics and production systems. You'll define SLIs and SLOs, lead incident response as commander, drive observability strategy end to end, and mentor cloud/platform engineers as you go.

You'll work closely with Product and Engineering, balancing speed, quality, and long-term reliability, while making the architectural calls that keep our systems resilient under load.

Responsibilities

Reliability & Incident Management

• Lead incidents as commander: set and revise severity, and know when to mitigate first and diagnose later
• Own the incident record and timeline standard, including the link between deployments and incidents
• Communicate with stakeholders while an incident is active
• Conduct blameless postmortems and drive toil identification and elimination as measured work

Observability

• Implement the three pillars of observability (logs, metrics, traces) end to end
• Design metrics and query strategy — recording rules, dashboard design that separates on-call needs from analyst needs
• Define SLIs and SLOs for critical services, choosing the indicator that reflects user experience over the one that's easiest to measure
• Design alerting systems — routing, escalation, deduplication, and alert fatigue reduction (multi-window burn-rate alerts)

Platform & Production Systems

• Design workload health signals — liveness, readiness, and startup probes — and reason about workload lifecycle (SIGTERM handling, termination grace periods, connection draining)
• Build runbook automation and self-healing systems to reduce operational toil
• Contribute to CI/CD framework improvements and cost optimization initiatives

Technical Leadership

• Make architectural decisions for reliability-critical systems
• Mentor cloud/platform engineers
• Influence technical direction on infrastructure and platform decisions

Requirements

• 5+ years of experience in SRE, Cloud, or Platform engineering roles
• Profound knowledge of SRE principles and incident response practices
• Profound knowledge of the observability stack: log aggregation and query design, metrics/dashboard design, and distributed tracing
• Profound knowledge of Kubernetes cluster operations and workload objects (Deployments, StatefulSets, Jobs, DaemonSets) and their failure modes
• Solid to profound knowledge of networking fundamentals: DNS as infrastructure, TLS certificate lifecycle, load balancing and reverse proxies
• Hands‑on experience with Infrastructure as Code (Terraform or equivalent)
• Profound knowledge of process and OS-level architecture trade-offs as they apply to containers (immutable infrastructure, image strategy)
• Scripting proficiency (Bash or Python) for tooling and automation
• Strong Git and collaborative workflow experience

Nice to Have

• Experience with chaos engineering or failure injection programs
• Exposure to multi-region or multi-cloud design trade-offs
• Familiarity with service mesh implementations
• Prior mentoring or technical leadership experience
• Certifications such as Site Reliability Engineering (SRE) Foundation or Observability Foundation
• Contributions to open-source observability or Kubernetes tooling

What We Offer

Permanent contract.

Flexible working hours (core hours: 09:30 – 13:30).

Remote‑first culture, with the option to work from our Granada office.

30 working days of annual leave, plus December 24th and December 31st as additional company days off that do not count against your holiday allowance.
