Job Summary

This is a captivating and exciting time to join Partnerize. We are at a pivotal point in our tech progression, looking to significantly expand our technical estate, scale the platform, and replace existing legacy systems with modern solutions. You will play a vital role in the ongoing operationalisation and management of our entire platform portfolio found in our on‑prem datacentres and AWS cloud: Partnerize, BrandVerity, Ascend, and our recent acquisition, Konnecto.

While there will be a key focus on integrating and supporting Konnecto's advanced data and AI layers, a critical pillar of your mission will be spearheading the development of our enterprise on‑prem containerisation solution. This initiative is designed to fundamentally shift our engineering culture towards a "you build it, you own it" model. By providing robust, automated container platforms, you will empower our Engineering teams to deploy quickly and independently, significantly reducing the bottleneck created by relying solely on the TechOps department.

We are looking for a Lead SRE who is both a deep technical expert and a capable mentor. In this role, your primary responsibility is ensuring our diverse, hybrid systems remain available, scalable, and secure. You will act as an authoritative Subject Matter Expert (SME), championing developer autonomy, driving IT systems security policies, and working closely with the security compliance team to protect our platforms from threats while driving continuous integration and delivery. This role will report into the SRE and Application Manager providing them with technical guidance and recommendations while being the technical lead for the SRE team.

The Team

You will be responsible for ensuring the continuous development and progression of team members. We are looking for a player/coach who can mentor, empower, and up‑skill talent. We have a mix of technical generalists, specialists, and junior engineers; you will help identify their strengths and constructively develop areas of weakness, guiding their technological career paths as we transition to a DevOps‑centric operating model.

The Operational Reality

You will operate in a fast‑paced, high‑velocity environment where your work directly and visibly shapes the company's architectural future. This requires a highly adaptable and pragmatic leader who can balance strategic project delivery with hybrid‑estate maintenance. By applying modern incident management frameworks to troubleshooting and ticket management, you are responsible for ensuring all issues across our estate are addressed decisively and efficiently.

As a Lead SRE, You Will:

• Strategic & Operational Management

• Hybrid Platform Engineering & Konnecto
• Build software and systems to manage platform infrastructure across on‑prem and AWS. Take the lead technical role in integrating and modernising Konnecto's architecture, ensuring its data ingestion and AI logic layers scale securely.
• FinOps / Cloud Cost Optimisation

• People Leadership & Talent Development
• Mentorship
• Deliver coaching sessions to the team and individuals, acting as a technical escalation point and fostering a culture of knowledge sharing.
• Workload Management
• Scope the work coming into the SRE team, prioritise hybrid‑estate maintenance vs. project delivery, and delegate tasks to team members to ensure prompt resolution.
• Security & Architecture

• Security Strategy
• Drive improvements to Partnerize platforms' security through strategic planning, vulnerability assessments, and security testing.
