SRE & Platform Engineering Lead
First seen by Alion on Aug 7, 2026.
Job Description :
We're looking for a SRE and Platform Engineering Lead to run that function. You'll lead a team of ~11 engineers spanning SRE, DevOps, SecOps, Data, and Release, and you'll own the platform's reliability, cost efficiency, and delivery velocity end-to-end.
You'll report directly to the CTO and sit at the intersection of infrastructure strategy, security posture (including our active SOC 2 push), and the day-to-day engineering culture that determines whether Mediamint Client's 37 day sprint cadence is sustainable or just aspirational.
This is a hands-on leadership role where you'll set technical direction, unblock your team, and represent platform engineering in company-wide roadmap conversations.
What You'll Own :
Team Leadership & Culture :
- Lead and grow a ~11-person team across DevOps, SRE, SecOps, Data, and Release functions.
- Set clear goals, career paths, and performance expectations for engineers across disciplines.
- Build a healthy, sustainable on-call culture with clear escalation paths and blameless postmortems.
- Mentor senior ICs and develop the next layer of technical leads within the team.
Platform Reliability & Infrastructure Roadmap :
- Own uptime, performance, and scalability of the infrastructure underpinning Mediamint Client's 35+ (scaling to 150+) live AI agents.
- Define and drive the multi-quarter infrastructure roadmap in partnership with the CTO.
- Establish SLOs/SLAs and the monitoring, alerting, and incident response practices to meet them.
- Ensure the platform's modular "Lego" architecture scales cleanly as agent volume grows.
AWS Cost Optimization & Cloud Strategy :
- Own AWS cost optimization as an active, ongoing initiative, not a one-time cleanup.
- Drive rightsizing, reserved capacity planning, and architecture decisions that balance performance with spend.
- Partner with finance and leadership on infrastructure budgeting and forecasting.
CI/CD & Release Engineering :
- Own the CI/CD pipelines that let engineering ship new Mediamint Client modules in 37 day sprints.
- Continuously improve deployment safety, speed, and rollback capability across environments.
- Drive release engineering practices that support rapid, frequent, low-risk shipping at scale.
Security & Compliance Enablement :
- Partner closely with SecOps and Security/Compliance functions to support MediaMint's SOC 2 compliance program.
- Ensure infrastructure and access controls align with WorkOS SSO rollout and broader identity governance goals.
- Champion security-by-default practices across the platform engineering org.
Data Platform & Analytics Enablement :
- Guide the Data function within your team to support agentic analytics initiatives across Mediamint Client.
- Ensure data infrastructure is reliable, well-governed, and ready to power increasingly sophisticated agent behaviors.
Required Qualifications :
- 8+ years of engineering experience, including meaningful time leading platform, infrastructure, SRE, or DevOps teams.
- Direct people management experience, ideally leading teams of 8+ across multiple technical disciplines.
- Deep AWS expertise, including cost optimization at scale across a multi-service, multi-account environment.
- Proven ownership of CI/CD and release engineering in a fast-shipping, high-velocity engineering environment.
- Experience building or maturing on-call and incident response practices.
- Track record of partnering with security/compliance teams, ideally including SOC 2 or similar frameworks.
- Strong executive communication skills, comfortable reporting to and influencing a CTO on roadmap and tradeoffs.
Preferred Experience :
- Experience scaling platform infrastructure for an AI or automation-heavy product.
- Familiarity with SSO/identity platforms such as WorkOS or Okta.
- Background supporting data platforms or analytics infrastructure.
- Experience in a services-to-product transformation or high-growth SaaS environment.
