Senior DevOps Engineer - Client Implementation

Join TRG Screen and be part of a dynamic team at the forefront of subscription spend management innovation.

The Role:

We are looking for a Senior DevOps Engineer to join our growing team in a client-facing role. You will be the technical voice of our Data Caching platform, Submarine, for our prospects and clients, supporting Sales through pre-sales conversations and owning the journey through to a live, supported deployment.

You will explain how the Submarine environment is designed and built, capture and analyse each client's current infrastructure and market data set-up and determine whether we can deploy as standard or need to adapt our methods. You will then lead the implementation of Submarine in the client environment and remain available as a technical point of contact for support issues once live. This role suits someone who can take an ambiguous client request and turn it into a clear plan, rather than someone who needs fully specified tickets to get things done.

Key Responsibilities Pre-Sales and Client Discovery:

• Partner with Sales to present and explain the Submarine architecture, deployment model, and environment set-up to client technical, security, and infrastructure teams.
• Capture and document each client's current environment, including infrastructure, network, security controls, and market data integrations and protocols.
• Assess fit between the client environment and our standard deployment approach, identify gaps, and recommend whether we implement as-is or adapt our methods.
• Respond to technical questionnaires, security reviews, and due diligence requests alongside Sales and Engineering.

Implementation and Delivery:

• Lead end-to-end implementation of Submarine in client environments, from solution design through deployment, configuration, testing, and go-live, with minimal disruption to clients.
• Design and deploy cloud-native infrastructure using Infrastructure as Code (Terraform, Ansible, CloudFormation) and manage containerised workloads in Docker and, where required, Kubernetes.
• Adapt and automate deployment pipelines (CI/CD) to fit client change-control and release processes.
• Troubleshoot application and integration components, such as connectivity to RabbitMQ and remote SFTP servers, and other issues outside standard interfaces.
• Configure client-specific data transformation and routing using JavaScript and API access within Submarine.
• Apply security and compliance best practices, including system hardening, patching, and alignment with client security requirements.

Support and Continuous Improvement:

• Act as a technical escalation point for support issues, diagnosing and resolving problems in live client environments.
• Produce clear technical documentation, including runbooks, architecture diagrams, and client-specific configuration records.
• Define disaster recovery and fault tolerance approaches for client deployments.
• Feed client learnings back to Product and Engineering to improve deployment tooling, standards, and the Submarine platform.
• Mentor colleagues and promote DevOps best practices across the Implementation team.

Skills and Qualifications Essential:

• 6+ years in DevOps, Site Reliability, or Systems Engineering, including senior-level ownership of infrastructure.
• Proven, hands-on experience in a client-facing technical role (pre-sales engineering, implementation, professional services, or similar), including handling clients who push on scope. Able to explain complex technical topics to technical and non-technical audiences.
• Strong hands-on experience with Infrastructure as Code tools (Terraform, Ansible, Pulumi).
• Experience with Docker and container orchestration (Kubernetes, EKS, or similar).
• Solid understanding of cloud platforms (AWS) and cloud-native patterns.
• Experience building and maintaining CI/CD pipelines (GitHub Actions, GitLab CI, Azure DevOps, Jenkins).
• Working understanding of JavaScript and how the components fit together.
• Excellent troubleshooting skills across networking, messaging (e.g., RabbitMQ), and file transfer (e.g., SFTP) components.
• Understanding of security best practices and compliance frameworks, and experience working within enterprise security reviews.
• Excellent written and verbal communication, including producing detailed technical documentation and runbooks.

Preferred:

• Experience in financial services or market data environments (we will consider exceptional candidates without this).
• Basic understanding of financial instruments (e.g. futures, bonds, equities) to support day-to-day client conversations.
• Familiarity with market data systems (Market EDM, Golden Source, Cadence/Cadis, or CRD from State Street).
• API integration experience (REST APIs, data requests, response handling).
• Experience with configuration management tools (Chef, Puppet).
• Experience with observability platforms (Datadog, New Relic, Prometheus/Grafana).
• Knowledge of GitOps tools (ArgoCD, Flux), policy-as-code (OPA, Kyverno), and Docker image pipelines and artifact repositories.
• Experience supporting a production service, including on-call or support rotas.

Soft Skills:

• Confident presenter who builds credibility quickly with client technical teams.
• Comfortable working asynchronously and collaborating across Sales, Engineering, Support, and clients (Slack, Teams).
• Genuine ownership of their work and their clients: sees things through to the end, and treats problems, including incidents, as theirs to solve.
• Understands the context behind a client request and distils it into clear next steps, without needing a detailed ticket.
• Judges the level of effort involved and spots and flags scope creep early.
• Manages their own deadlines without close supervision.
• Stays organised across a large amount of scattered information, through memory or their own system, so nothing is dropped. This matters even more during incident response.
• Spots potential issues early and suggests improvements without being prompted.
• Ability to evaluate trade-offs and make pragmatic recommendations when client environments differ from our standard.

Working With Us:

You will work closely with business analysts, engineering teams, Sales, and Support, deepening your understanding of market data systems as you go. You will be required to work US Hours and support out of hours client incidents should they arise.
