Senior Platform & Site Reliability Engineer

EVA Equity Partners acquires and scales B2B SaaS companies. Our portfolio runs on a shared platform and reliability foundation that is being built in parallel with active acquisitions. You will be the person who builds and owns that foundation, the engineering backbone of how every product in our portfolio is built, deployed, and kept alive.

The Role

This role carries full architectural and operational ownership of the platform layer across EVA and its portfolio. The Cloud Architect owns AWS infrastructure standards, VPCs, account structures, networking, and compute design. Everything outside that lane is yours: the CI/CD platform, the observability and reliability stack, the event streaming infrastructure, the deployment pipelines, and the incident engineering model. At EVA, architectural decisions are yours to make and defend, standards are yours to define and enforce, and the reliability of 20+ enterprise SaaS products depends on what you and your team build. This is also an AI-native engineering organisation, and you are expected to use automation and AI-assisted tooling to reduce toil where it is practical and safe to do so.

What You Will Own

Full architectural ownership of the non-AWS toolchain, including CI/CD, observability, event streaming, automation, secrets, and deployment infrastructure. Define, build, and enforce platform standards across portfolio products using Terraform IaC for all infrastructure. Own the event streaming architecture, operational standards, and health monitoring across all products using real-time pipelines. Build and maintain CI/CD pipelines using GitHub Actions across all portfolio products, automating triage and retry logic for known failure classes. Own the full observability stack, including Grafana, Prometheus, and Loki, with SLOs and error budgets defined per product. Lead platform audit and gap analysis for every new acquisition, sequencing migration plans to avoid disrupting live operations.

Why This Role

EVA's platform function is being built from the ground up. You will have architectural ownership of the entire non-AWS platform layer across a growing portfolio of enterprise SaaS products, and the freedom and responsibility to build the reliability and delivery culture of the organisation.

Required Skills

What We're Looking For

8-12 years in platform engineering, DevOps, or SRE, with clear evidence of increasing ownership over time. Strong Terraform depth across multi-environment, multi-account setups. CI/CD ownership across a multi-product environment with GitHub Actions. Experience with event streaming infrastructure at production scale, including design, operations, reliability, and cost management. Hands-on Grafana, Prometheus, and Loki in production. AWS operational depth across ECS, EKS, RDS, IAM, VPC, CloudWatch, and Cost Explorer. SRE fundamentals including SLOs, error budgets, on-call design, and post-mortem culture. Acquisition or greenfield platform integration experience strongly preferred.

How You Work

Comfortable operating across multiple products simultaneously without dropping standards. Cost-efficiency instinct, optimising spend as a habit rather than a project. Treats automation as a tool for eliminating toil, not a substitute for engineering judgement. Documents decisions, enforces standards through code, and builds platforms that other engineers find intuitive to use.
