BTG Pactual is looking for an experienced SRE Engineer to take on a hands‑on technical lead role within our Technology Team in London.

This role is hybrid, requiring a minimum of three days per week in the London office, with flexibility to increase attendance to four or five days per week as needed.

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 planning 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 escalated 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.

Required Skills & Experience

• Bachelor’s degree in Computer Science, Engineering or a related field, or equivalent practical experience.
• 6+ years of hands‑on experience in cloud operations, infrastructure management and automation, with at least 4 years focused on AWS.
• Proven track record delivering scalable, reliable cloud‑based solutions.
• Demonstrated experience leading an engineering team of 5 or more people.
• Strong proficiency in infrastructure‑as‑code tools (Terraform, Ansible, CloudFormation) and scripting languages (Python, Bash).
• Solid understanding of CI/CD principles and tooling, with hands‑on experience building and maintaining automated pipelines.
• Experience with container orchestration and Kubernetes.
• Familiarity with observability and monitoring tools (e.g., Datadog, Prometheus, Grafana, Zabbix).
• Strong troubleshooting skills across cloud networking, Linux systems and distributed services.
• Excellent communication skills and ability to collaborate with cross‑functional and international teams.
• Strong organisational skills with the ability to prioritise and manage competing demands in a fast‑paced environment.

Beneficial

• Azure cloud experience.
• Exposure to ITSM platforms and capacity planning tooling.
• Experience with Disaster Recovery design and automation.

What We Look For

• A proactive, self‑directed approach – you take ownership and drive outcomes with minimal supervision.
• A genuine commitment to continuous learning – actively developing your own skills and staying current with emerging technologies, tools and SRE best practices.
• 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.
• Willingness and availability to participate in on‑call support as per the defined rota.
• Commitment to a hybrid working model with a minimum of three days per week in the office, and flexibility to increase attendance as business needs evolve.
