We’re looking for an exceptional Engineering Manager, Platform, to join Definely during a pivotal stage of growth. This is a player-coach role that combines hands-on engineering with technical leadership, where you’ll shape the infrastructure, APIs, and developer experience that enable product teams to ship quickly, securely, and reliably at scale.
You’ll guide the evolution of our document processing pipelines, data stores, and AI integrations, while championing DevOps/SRE practices, observability, security, and cost efficiency. You’ll influence engineering culture, mentor engineers, and help define architectural direction across the company.
This is an opportunity to build the foundations of a global SaaS platform, making technical and strategic decisions that will define the next phase of Definely’s growth.
What you\’ll do:
- Platform Architecture & Strategy: Own and evolve the technical roadmap for Definely’s platform services. Design scalable, resilient, and cost-efficient cloud-native systems for document and AI workloads. Define and uphold engineering principles and standards across teams. Partner with Product, Security, and Finance to align platform priorities with business goals.
- Infrastructure & Operations: Lead adoption of containers, Kubernetes, and Infrastructure as Code (Terraform/CDK). Build and enforce best practices in observability, monitoring, and incident response. Set and maintain SLOs/SLAs for platform reliability and performance. Drive FinOps practices: forecasting, monitoring, and optimizing infrastructure spend. Build internal tooling, templates, and pipelines to accelerate product delivery. Champion CI/CD adoption and empower engineers with self-service deployment capabilities. Improve developer productivity by standardizing environments and streamlining workflows.
- Security & Compliance: Partner closely with the ISO and Security teams to maintain compliance with ISO 27001, SOC 2, and GDPR. Implement identity and access management, secrets management, and network security best practices. Drive a security-first culture across platform and product teams. Act as a technical mentor and coach, fostering growth and ownership within the team. Guide architectural decisions across product areas, balancing speed and long-term scalability. Influence engineering culture, encouraging adoption of DevOps and SRE principles. Collaborate with leadership on vendor evaluation, partner selection, and build-vs-buy decisions.
What you\’ll bring:
- Proven experience leading or building platform teams in a high-growth SaaS environment.
- Expertise with AWS (preferred) / Azure / GCP, Kubernetes, IaC, CI/CD, and observability.
- Strong API and event-driven architecture skills; familiarity with asynchronous pipelines.
- Track record of designing secure, multi-tenant architectures.
- Excellent communication skills, with the ability to explain trade-offs to non-technical stakeholders.
- A Bachelor’s Degree in Computer Science (or equivalent experience).
We\’ll be lucky if you have:
- Production experience integrating Microsoft Word (Office.js) add-ins with backend services; knowledge of M365 auth patterns.
- Hands-on experience with LLM/AI platformization (RAG, vector search, evals, safety/guardrails).
- Experience with FinOps practices and infrastructure cost management.
- Prior exposure to global scaling challenges (latency, data residency, multi-region deployments).
What we offer:
- Competitive Salary: Starting at £95,000
- Annual bonus: Recognising and rewarding the results you deliver, aligned with overall company success.
- Equity: We want everyone to share in Definely’s success, so you’ll receive stock options as part of your package.
