Site Reliability Engineer - Aws Engineer

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.
• Private health insurance.
• Your choice of MacBook or Lenovo.
• Unlimited access to learning platforms.
• Learning time during working hours.
• Budget for certifications and specialised training.
• Employee referral programme.
• Opportunity-based bonuses.
• Stable, long-term projects.
• Real opportunities for professional growth.
• The opportunity to play a key role in the growth of a modern Software Engineering company.
