Senior Platform Engineer

We are looking for a Senior Platform Engineer to help design, build, and evolve our internal platform that supports a cloud-native, security-focused SaaS running on AWS, Kubernetes (EKS), and PostgreSQL.

This role combines strong software engineering with deep infrastructure and DevOps expertise.

You will primarily focus on building scalable, reusable platform capabilities that improve developer experience and reduce operational toil-while also being comfortable handling occasional hands-on DevOps tasks when needed.

This is not a pure operations role, and not a pure application backend role. It sits intentionally in between.

Requirements:

Must-have

5+ years experience in Platform Engineering, DevOps, SRE, or Infrastructure Engineering
Strong hands-on experience with Kubernetes (EKS) in production
Strong experience with AWS (networking, IAM, compute, storage)
Strong experience with Infrastructure as Code (Terraform)
Production-level programming experience in Python
Experience designing systems or tooling used by other engineers
Solid understanding of Linux, networking, and distributed systems

Nice-to-have:

Experience with PostgreSQL in production (RDS / Aurora PostgreSQL preferred)
Familiarity with database lifecycle concerns: upgrades, backups, monitoring, and migrations
Experience with ArgoCD and GitOps workflows
Experience building Helm libraries or shared charts
Experience with internal developer platforms (IDP), Backstage, or similar
Experience building Kubernetes operators or controllers
Experience in security-focused or compliance-heavy environments

Responsibilities:

Platform Engineering & Developer Enablement

Design and build internal platform components that abstract and standardize infrastructure, deployments, and operational workflows
Improve and evolve our GitOps-based delivery model (ArgoCD)
Build reusable Helm charts, libraries, and deployment patterns
Create tooling and automation that enable teams to self-serve safely and consistently
Treat the internal platform as a product, with clear ownership and documentation

Infrastructure, Data & Cloud Foundations

Design and maintain Terraform-based infrastructure across AWS environments
Help design and operate PostgreSQL-based data infrastructure (e.g. RDS / Aurora PostgreSQL)
Build automation and standards around database provisioning, upgrades, backups, and reliability
Collaborate with application teams on schema migrations and performance considerations
Define standards for networking, IAM, security, and scalability

Kubernetes & Observability

Build and improve abstractions on top of EKS / Kubernetes
Define and standardize observability patterns (Prometheus, Grafana, logging)
Improve reliability by design, not by firefighting

Occasional Hands-on DevOps Work

Assist with operational tasks when needed, such as:

Creating or improving Helm charts
Supporting EKS version upgrades
Improving ArgoCD configurations
Helping troubleshoot complex production issues

These tasks are expected to be occasional and purposeful, often feeding back into longer-term platform improvements.

What success looks like:

Platform components are reliable, documented, and widely adopted
Developer teams can deploy and operate services with less friction
Operational toil decreases over time
PostgreSQL and Kubernetes platforms are stable, observable, and predictable
Clear balance between platform ownership and occasional hands-on ops support
