Senior Platform Engineer

Join Authorium, a rapidly growing company in the AI-driven workflow space. As a Senior Platform Engineer, you will play a crucial role in shaping the technical integrity of our platform and driving our next phase of expansion. You will work in-person in our San Francisco office, collaborating closely with our engineering leadership and making architectural decisions that impact multiple teams and services. This is a unique opportunity to be at the forefront of our product innovation and engineering excellence.

• Architecting the Platform: Own the most complex infrastructure work — designing internal developer platforms, CI/CD pipelines, deployment abstractions, and the foundational systems that product teams build on top of.
• Technical Sovereignty: Make architectural decisions around reliability, scalability, and developer experience that hold up across multiple teams and services. You'll write ADRs and lead the modularization of platform primitives and shared infrastructure.
• High-Bandwidth Collaboration: Work in-person (Monday–Thursday) with our SF engineering leadership to design platform capabilities, resolve production incidents, and translate engineering pain points into infrastructure solutions.
• AWS Depth: Hands-on experience with ECS/EKS, CloudWatch, IAM, VPC design, Parameter Store, and modern IaC tooling (Terraform, Pulumi, CDK)
• San Francisco Based: Energized by an in-office (Monday-Thursday) collaborative culture
• Systems Thinker: Proven track record designing and operating reliable, scalable infrastructure — including service meshes, internal tooling, and developer-facing APIs or abstractions
• Developer Experience Focus: Experience building internal platforms, golden paths, or self-service deployment tooling that measurably improves engineering velocity
• Security Minded: You treat security as a first-class platform concern — deep understanding of secrets management, network policies, IAM models, and supply chain security
• High-Agency: You identify platform gaps before they become incidents. You partner with engineering teams to turn reliability pain into well-scoped platform investments
• 6+ years of professional experience in platform, infrastructure, or DevOps engineering, with strong fundamentals in distributed systems, networking, and cloud architecture
• Quality Obsessed: A history of high-quality infrastructure-as-code, runbooks, and a drive to build self-service systems that reduce toil for the entire engineering org
• Observability & Reliability: Experience owning SLOs/SLAs, building out logging/metrics/tracing stacks (Datadog, OpenTelemetry, etc.), and leading incident response
• Grow Stage Veteran: Previous experience at a company in the $5M–$30M ARR range where you were one of the senior-most individual contributors
• Regulated Industry Experience: Previous work in compliance-heavy environments such as GovTech, FinTech, or HealthTech (FedRAMP, SOC 2, HIPAA) — ideally with a focus on infrastructure compliance controls
