Site Reliability Engineer II

Role Description:

Key Responsibilities

Software Systems Design

- Create software that will address availability, scalability, latency, and efficiency for Bookings’ systems/services

- Have a product-based mindset that takes both customer and future roadmap plans into account. Development efforts are focussed on solving for a general case in tech or related subsystem of responsibility while not ruling out that tooling or product can be leveraged by other teams

Technical Incident Management

- Take ownership of how to procedurally deal with emergency situations. SRE should write the playbook on how to deal with a system/service degrading or even a full outage

- Conduct post-mortem meetings (RFOs) to ensure learnings are applied and shared in case of incidents

- Take part in our incident management program by participating in on-call rotation.

- Be available to provide expertise and feedback for our service health program

Automation and Toil Reduction

- Build automation and application orchestration to prevent recurrent problems and to reduce human labor

Observability (Monitoring and Alerting Improvements)

- Implement monitoring and alerting. This might not always be writing the software itself but could also be to create the best practices around how to monitor and alert for a system/service

- Engage in service capacity planning and demand forecasting, software performance analysis and system tuning

Architectural Guidance

- Maintain holistic knowledge and understanding of a system/service instead of only knowing some fraction of the problem space

- Create, document and implement Booking Reliability Engineering best practices.

- Collaborate with other teams and tech POs to support them in building reliable and scalable systems/services for their users and stakeholders

- Influence the business and tech colleagues to adapt engineering, reliability and security best practices

Community Involvement

- Take an active part in educating and skilling up members of our engineering community

Requirements of special knowledge/skills

- Proficiency in the core skills of a software developer: coding, large-scale software design & scaling, complexity analysis, algorithms, data structures, design patterns
- Expertise in source control management such as Git, Bitbucket & Infrastructure provisioning with Terraform.
- Solid hands-on experience with experience with configuration management tools ( Ansible & Puppet)
- Deep understanding of Unix/Linux systems internals and networking; this includes topics like: kernel, shell and client-server protocols
- Proficiency in Unix/Linux system administration (Redhat/CentOS)
- Networking: significant knowledge and understanding of network theory, such as different protocols (TCP/IP, UDP, ICMP, etc), MAC addresses, IP packets, DNS, OSI layers, and load balancing)
- Extensive on design, configuration and implementation for a system/service in a large scale production environment (systems engineering and architectural skills)
- Expertise in various AWS services & their use cases. (EC2, Network, Lambda, IAM and more)
- Eagerness to keep up with latest developments in technology
- Connection with the worldwide SRE community
- Exhibit the following behaviours: be curious; be data driven; have a systematic problem solving approach; constantly aiming to improve systems/services
- Should have minimum 6 to maximum 10 years of experience in a similar role.

- Architectural Guidance

- Advise product teams towards a technical solution that meets the functional, nonfunctional & architectural requirements by challenging the rationale for an application design and providing context in the wider architectural landscape

- Set a clear direction for a technical capability by evaluating and aligning the target architecture improvements, reframing architectural designs and decisions for varied stakeholder

- Critical Thinking

- Find solutions to difficult or complex issues by applying different skills and techniques like analytical thinking, lateral thinking, and logical reasoning
