Site Reliability Engineer

Job Overview

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.

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.

Required Qualifications

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:

Initial Screening Call: An introductory conversation with the Talent Acquisition/HR team to evaluate background, operational scope, and career trajectory.

Hiring Manager Interview: A 1-hour in-depth technical domain screen focusing on core systems engineering, network topology, and architecture principles.

Technical Evaluation: A 2-to-3-hour practical interview incorporating a live coding and infrastructure automation exercise.

Executive Interview: A final strategic conversation with the firm’s three Founders to discuss corporate vision and collective cultural fit.
