Site Reliability Engineer - Technical Lead (initial 12 month FTC)

About Us

Founded in 1983, BTG Pactual is now the largest investment bank in Latin America. We're committed to a future where investing is dynamic and straightforward, which is why we're undergoing a digitization and expansion process across various fronts. Our entrepreneurial mindset allows us to empathize with our clients and understand their challenges, leading to swift, autonomous, and bureaucracy-free solutions. Renowned for our excellence, flexibility, and versatility, we serve clients from our offices in Brazil, Chile, Colombia, Peru, Mexico, Argentina, the United States, United Kingdom, Portugal, Spain, Luxembourg and Saudi Arabia.

The Role

BTG Pactual is looking for an experienced SRE Engineer to take on a hands-on technical lead role within our Technology Team in London. You will own and drive automation and infrastructure integration efforts across cloud and on-premises environments in a fast-paced, global organisation.

In this role, you will guide and develop a small team of engineers while remaining deeply involved in technical delivery yourself. You will collaborate with agile, cross-functional teams and contribute to DevOps practices including CI/CD, deployment automation, automated testing, and multi-cloud architecture. We offer the freedom to explore new languages, development standards, and methodologies.

This is a temp to perm opportunity for an initial period of 12 months, on an Fixed-Term Contract (FTC) basis. Due to ongoing growth within our Technology Team, the intent will be for this position to transition into a permanent role upon the successful completion of the initial 12 month period, subject to performance and business requirements. 

This is currently a hybrid role requiring a minimum of three days per week in the London office. The successful candidate must have the flexibility to increase office attendance to four or five days per week when business needs, project demands, or critical incidents require on-site presence. As the company continues to evolve, office attendance expectations may be adjusted over time to align with business needs.

Role Responsibilities 

• Lead and develop a team of engineers, organising and prioritising workloads, tracking project plans, and communicating status to stakeholders.
• Execute hands-on technical tasks alongside the team, acting as a senior individual contributor as well as a lead.
• Define technical architectures for robust, resilient, high-performance, and scalable infrastructure systems.
• Implement and maintain automation across AWS and Azure cloud environments and on-premises setups, using tools such as Terraform, Python, CloudFormation, and Ansible.
• Build and maintain CI/CD pipelines to support continuous integration and deployment.
• Leverage AI coding platforms and tools (e.g., GitHub Copilot, Claude Code) to accelerate development, improve code quality, and enhance team productivity.
• Develop scripts and integrations using APIs to automate operational workflows.
• Implement Disaster Recovery automation and lead regular HA/DR tests to minimise RTOs.
• Build and maintain automated monitoring, alerting, ITSM, and capacity plan Sitening solutions.
• Troubleshoot and resolve complex infrastructure and reliability challenges.
• Document processes, procedures, and environment configurations to a high standard.
• Provide frequent and organised status reports of the team’s activities, communicating both technical detail to engineering peers and clear summaries to management.
• Develop and execute training and upskilling strategies for team members.
• Work closely with IT project managers, developers, and business stakeholders to shape and deliver solutions.
• Manage vendor relationships and escalate hardware, software, or service issues when required.
• Participate in an on-call support rota, following a pre-defined schedule, to provide after-hours and weekend coverage for critical infrastructure and reliability incidents.
• Execute planned production environment changes outside of standard business hours, including evenings and weekends.

Beneficial

What We Look For

• Clear, confident communication — able to present ideas and translate technical concepts for non-technical audiences.
• Attention to detail and a high bar for quality in both code and documentation.
• Ability to work well under pressure, responding to critical incidents and requests calmly and efficiently.
• Strong reporting and documentation skills — able to produce clear, structured updates on team activities for both technical and non-technical audiences.
