Reporting

The Site Reliability Engineer reports directly to Project Manager and Head of Solutions.

Duties and Responsibilities

The Site Reliability Engineer is responsible for the reliability, performance, and operability of production systems, in addition to improving software product delivery in the areas of provisioning, monitoring, securing, deploying, scaling, maintaining, and system hardening. This role combines DevOps automation with reliability engineering: the engineer not only builds the pipelines and infrastructure, but also understands how the systems behave under load, diagnoses issues down to the database and operating system level, and writes real code to remove toil. A typical day involves monitoring systems, supporting the project teams, and collaborating with the software development, architecture, and infrastructure teams to derive best practices for continuous improvement. This role requires an individual to be hands-on to build, setup, monitor, and maintain running systems primarily on AWS, with ability to work on on-premise or other cloud platforms. The role is also expected to keep cloud spend efficient and predictable while meeting reliability targets.

The Site Reliability Engineer is responsible for tasks in the following areas:

Design, provision, and maintain cloud infrastructure with primary focus on AWS services including container orchestration (ECS/EKS/App Runner), serverless computing, databases, API management, and CDN solutions.
Support infrastructure deployment and management across AWS, on-premise, and other cloud providers as required.
Establish idempotent CI/CD pipelines using infrastructure-as-code tools (Terraform preferred) and CI/CD platforms to automate configuring, provisioning, packaging, testing, and deployment.
Define and operate reliability targets - SLIs, SLOs, and error budgets - for the services owned, and drive engineering work when error budgets are burned.
Configure and deploy monitoring, alerting, tracing, and observability platforms to provide visibility into system health, performance, and incident management.
Standardize the processes for managing, maintaining, and securing Linux-based environments to ensure consistent and timely setup, configuration, and availability.
Implement security best practices including system hardening, vulnerability management, identity and access management, secrets management, and incident response for production environments.
Draft and maintain detailed, up-to-date technical documentation and user guides.
Analyze and tune system performance end to end - application latency, runtime, operating system and kernel parameters, network, and database (slow queries, indexing, lock contention, connection pooling, replication lag).
Own the incident lifecycle: detection, triage, mitigation, root cause analysis, and blameless postmortems; drive follow-up actions to prevent recurrence.
Apply proper architecture guidelines to ensure highly available services.
Design for high availability and disaster recovery: capacity planning, failover, backup and restore drills, and defined RTO/RPO targets.
Own cloud cost optimization: monitor and forecast spend, right-size compute and storage, apply savings plans and reserved capacity, eliminate idle resources, and report cost per service or environment to stakeholders.
Write production-quality code (Python, Go, Bash) to build internal tooling, automation, and operational services; participate in code reviews with the development team.

Qualifications/ Experience Requirements:

· Bachelor's degree in Computer Science, Software Engineering, or equivalent practical experience

· 3+ years of hands-on DevOps/SRE experience operating production cloud infrastructure

· Strong experience with AWS cloud services (compute, storage, database, networking, serverless)

· Broad understanding of the tools and technologies within virtualization, infrastructure automation, configuration management, container concepts, observability, and Kubernetes orchestration

· Strong grasp of automated configuration management and Infrastructure as Code using Terraform and Ansible

· Prior experience establishing observability platforms including Prometheus, Grafana, and similar tools; experience with distributed tracing and log aggregation is a plus

· Experience building and maintaining CI/CD pipelines with modern automation platforms

· Strong Linux administration and system internals skills including system configuration, networking, resource and performance analysis, and security hardening

· Proficient with troubleshooting system issues related to hardware, custom software, and packaged middleware

· Proven incident management experience in production, including on-call participation and writing postmortems

· Demonstrated ability to analyze database performance (PostgreSQL, MySQL, or similar): reading query execution plans, indexing strategy, lock contention, and replication

· Practical experience with cloud cost management and optimization (AWS Cost Explorer, budgets and alerts, tagging strategy, right-sizing, savings plans / reserved instances)

· Solid coding ability in at least one general-purpose language (Python or Go preferred; Bash/Groovy as supporting) - able to build and maintain real tooling, not only glue scripts

· Strong communication in both verbal and written forms

· Excellent English communication

Desired qualifications:

· AWS certification (Solutions Architect or DevOps Engineer)

· Hands-on experience with message streaming platforms (Kafka, RabbitMQ, AMQ)

· Knowledge of microservices architecture patterns

· Experience defining SLO and error-budget policy at product or organization level

· Chaos engineering, load and stress testing experience (k6, Locust, JMeter)

· Database administration or query optimization at scale

· FinOps knowledge or certification, or experience running a cloud cost reduction programme
