Senior Site Reliability Engineer
Job Summary
The Senior Site Reliability Engineer is a key technical leadership role at the intersection of infrastructure, platform engineering, operational resilience, and developer enablement. At Partnerize, we operate a high-scale platform processing over a billion daily events across a hybrid estate spanning on-prem datacentres and AWS cloud infrastructure. You will play a critical role in ensuring our systems remain reliable, scalable, secure, and operationally efficient whilst helping evolve our engineering culture towards a modern “you build it, you own it” model.
This is not a purely operational support role. We are looking for an experienced technical leader and subject matter expert who can balance hands-on engineering with strategic thinking — someone capable of modernising legacy systems, improving observability and automation, and guiding engineers through increasingly complex distributed environments.
The Things You Care About
At the heart of our platform, we process and distribute performance marketing data at enormous scale, generating over a billion events across our infrastructure daily. Our systems power real-time decision making, partner attribution, analytics, and customer-facing products that require high availability and operational excellence.
As we continue to scale globally, we are evolving our infrastructure, modernising legacy systems, and investing heavily in automation, containerisation, observability, and platform reliability. We deploy to production multiple times a day and operate a hybrid environment spanning physical datacentres and AWS cloud services.
Our infrastructure and engineering ecosystem includes technologies such as Linux, Kubernetes, Docker, Kafka, MySQL, PostgreSQL, Redis, Python, Terraform, Ansible, Elasticsearch, Druid, and modern CI/CD tooling.
As a Senior Site Reliability Engineer at Partnerize, You Will:
Lead Reliability & Operations
Take ownership of platform reliability, availability, and operational performance across a complex hybrid estate supporting Partnerize, BrandVerity, Ascend, and Konnecto.
Drive Platform Modernisation
Help lead the transition from legacy operational models towards modern containerised infrastructure and self-service engineering platforms.
Champion DevOps Enablement
Empower development teams through automation, tooling, and platform improvements that support a “you build it, you own it” engineering culture.
Act as a Technical Authority
Provide technical leadership and guidance across infrastructure, distributed systems, security, observability, and operational best practices.
Improve Security & Resilience
Partner closely with security and compliance teams to strengthen platform security posture, conduct threat modelling, vulnerability assessments, and support secure-by-design engineering practices.
Mentor & Develop Engineers
Act as a player-coach within the SRE organisation, mentoring engineers, supporting technical growth, and helping shape future technical leaders.
Lead Incident Management
Take ownership during major incidents, driving clear communication, structured troubleshooting, and pragmatic resolution strategies across the wider business.
Drive Automation & Continuous Improvement
Continuously improve infrastructure, deployment pipelines, monitoring, and operational tooling to improve reliability, scalability, and delivery velocity.
You are an experienced Site Reliability Engineer with:
Deep Technical Expertise
Strong experience operating and supporting distributed systems at scale across Linux, cloud, and hybrid infrastructure environments.
Platform Engineering Experience
Hands-on expertise with Kubernetes, Docker, Terraform, Ansible, CI/CD pipelines, and infrastructure automation.
Strong Systems Thinking
The ability to troubleshoot complex systems methodically, balancing operational stability with long-term architectural improvements.
Security & Operational Awareness
Experience applying security principles within DevOps and distributed systems environments, including threat modelling, vulnerability assessment, and operational risk management.
Pragmatic Problem Solving
Confidence moving between strategic platform initiatives and low-level operational troubleshooting within high-pressure environments.
Leadership & Mentorship
Experience coaching engineers, delegating work effectively, and helping teams develop technical maturity and operational ownership.
Clear Communication
Strong interpersonal and communication skills with the ability to explain technical concepts, incidents, and trade-offs clearly to both technical and non-technical audiences.
Desired Qualifications & Competencies
Scaling Experience
You have operated systems that required reliability, observability, and performance at scale — and understand the operational realities of where systems fail.
Incident Leadership
You have led or contributed significantly to major incident management, driving resolution and learning through structured operational processes.
DevOps & Automation
Strong understanding of automation-first infrastructure practices and enabling engineering autonomy through tooling and platforms.
Modern Infrastructure
Experience working with containerisation technologies, orchestration platforms, and distributed event-driven systems such as Kafka.
Operational Excellence
Practical experience with monitoring, observability, capacity planning, and continuous improvement methodologies.
Agile & Lean Principles
Comfortable working within Agile environments and collaborating closely with engineering, product, and operational stakeholders.
Why This Role?
This is an opportunity to play a key role in shaping the future of Partnerize’s infrastructure and operational landscape. You will work on complex, large-scale systems, influence platform direction, modernise legacy environments, and help evolve our engineering culture towards greater autonomy, reliability, and scalability.
If you enjoy solving difficult technical problems, operating at scale, mentoring engineers, and driving meaningful platform improvements — this role offers both the technical depth and strategic impact to do exactly that.
