Descripción del empleo

We are seeking a Senior Site Reliability Engineer (SRE) to act as a core technical authority for a multi-cloud provisioning platform. You will drive automation, define reliability standards, and mentor engineering teams while ensuring the scalability, performance, and stability of production environments. Join us to design, build, and operate a highly automated platform that provisions infrastructure stacks across diverse cloud environments.

Your responsibilities:

• Architect and drive the reliability, scalability, and performance of a multi-cloud provisioning platform across production environments.
• Design and implement end-to-end automation pipelines to eliminate manual intervention and reduce technical toil.
• Define, monitor, and improve critical system health indicators (SLIs/SLOs), including latency, throughput, error rates, and capacity usage.
• Collaborate with product and cross-functional engineering teams to embed reliability and security considerations into the software development lifecycle (SDLC).
• Lead incident response management, including detection, triage, Root Cause Analysis (RCA), and implementation of long‑term preventative solutions.
• Identify platform bottlenecks, eliminate single points of failure, and reduce system complexity.
• Provide technical guidance and mentor engineering teams on reliability and architectural best practices.

We are looking for you, if you have:

• 10+ years of hands‑on experience in Software Engineering, DevOps, or Systems Infrastructure.
• 3+ years of advanced AWS experience, including cloud architecture and troubleshooting.
• 3+ years of production‑level Kubernetes experience, including cluster management, scaling, and provisioning.
• Hands‑on experience managing Kafka clusters, including partition management, broker scaling, replication, and monitoring consumer lag.
• Solid knowledge of MongoDB administration, including replica sets, sharded clusters, backup, and recovery strategies.
• Experience provisioning and tuning ClickHouse for analytical workloads, including columnar storage, distributed tables, and replication.
• Proven ability to work autonomously, make architectural decisions, and deliver production‑ready, automated infrastructure.
• Strong technical communication and collaboration skills, including the ability to align with Technical Leads and cross‑functional engineering teams.
• A proactive, problem‑solving mindset focused on system reliability, continuous improvement, and reducing platform complexity.
• Resilience and adaptability when handling critical production incidents.

We offer:

• Participation in interesting and demanding projects.
• A great, non‑corporate atmosphere.
• Possibility to work remote or hybrid (2 days per week from the office).
• Opportunities for development and promotion.
• Attractive package of benefits.
