Site Reliability Engineer

Location: Remote - UK working hours

Remote | Full-time

Compensation: £90K - £110K

We are hiring on behalf of our client, a high-performance financial technology organization specializing in advanced integration service products. The client develops and delivers an innovative, hosted integration platform that enables global financial institutions to maintain a flexible operational infrastructure without requiring internal engineering resources to address connectivity challenges across diverse trading venues.

The successful candidate will join a multi-disciplinary Site Reliability Engineering (SRE) team that actively champions a comprehensive automation culture. The mandate of this department is broad and impactful, covering everything from desktop and laptop infrastructure support to sophisticated data center server provisioning and global vendor network connectivity. While each team member brings distinct areas of technical specialization, the department operates under a shared-responsibility model for the entire production environment. The client is seeking a collaborative, growth-oriented professional who can meaningfully contribute to operational excellence while continuously developing their technical capabilities.

Key Responsibilities

• Automated Infrastructure Provisioning: Architect and build automated provisioning systems for global server and network architectures across both physical bare-metal environments and public cloud infrastructure (AWS, GCP).
• Continuous Delivery Pipeline Management: Evolve, maintain, and optimize the Continuous Delivery (CD) pipeline responsible for provisioning servers, configuring network switches, and deploying core software updates.
• External Stakeholder Interfacing: Interact directly with hardware vendors, telecommunications providers, and external financial institutions to manage connectivity and optimize remote operations.
• Collective System Ownership: Take shared ownership of the stability, performance, and monitoring of the end-to-end production environment alongside a tight-knit engineering team.

Requirements

Core Technical Competencies:

• Foundational Coding Capability: Practical experience with software engineering is required. While expert-level software engineering is not mandatory, proficiency in basic programming within a language of choice is necessary to construct functional code and utilities independently.
• Infrastructure Automation: Demonstrated experience working with software automation tools (specifically Ansible), combined with the coding agility needed to automate all configuration environments.
• Systems & Network Administration: Proven experience operating as a Systems Administrator or Network Engineer, paired with a balanced, comprehensive understanding of both domains.

Professional & Interpersonal Attributes:

• A constructive, open-minded, and self-motivated approach to technical problem-solving.
• A strong belief in lifelong learning and an awareness of evolving technologies.
• High professional autonomy, with a proven ability to take the initiative within a collaborative, team-oriented ecosystem.
• Experience managing third-party relationships, negotiating with vendors, procuring hardware, and supporting remote workforce initiatives via phone and email.

Preferred (Non-Essential) Qualifications:

• Familiarity with enterprise Authentication Protocols (e.g., SAML, OAuth2, Active Directory, Kerberos).
• Technical proficiency in Microsoft and Azure Active Directory.
• Hands-on exposure to Database High Availability (HA) frameworks, including clustering and replication models (e.g., PostgreSQL).

Benefits

• Competitive Base Compensation: Up to £110,000 per annum, commensurate with experience and skill set.
• Equity Participation: Allocation of company share options.
• Corporate Benefits: A comprehensive standard benefits package.
• Workplace Flexibility: Remote-first working philosophy with flexible arrangements within the UK and Europe, complemented by a modern workspace in Moorgate, London.



Interview Process

The client utilizes a transparent, structured four-stage evaluation process to ensure deep alignment across technical competencies and professional values:

1. Initial Screening Call: An introductory conversation with the Talent Acquisition/HR team to evaluate background, operational scope, and career trajectory.
2. Hiring Manager Interview: A 1-hour in-depth technical domain screen focusing on core systems engineering, network topology, and architecture principles.
3. Technical Evaluation: A 2-to-3-hour practical interview incorporating a live coding and infrastructure automation exercise.
4. Executive Interview: A final strategic conversation with the firm's three Founders to discuss corporate vision and collective cultural fit.
