[Hiring] Staff Software Engineer, Infrastructure @Hex

Role Description

Hex's infrastructure team owns all of our cloud infrastructure (compute, networking, datastores) along with CI/CD and observability, across a multi-tenant platform and single-tenant environments. Every engineer at Hex depends on what the infrastructure team builds.

We're growing in customers, in users, and in the kinds of data workflows our workload compute backend has to support. That growth has opened up a set of projects that would meaningfully change how fast the rest of engineering ships, and we're hiring to take them on.

We're looking for someone who will pick up one of those projects, own it start to finish, and leave it better than they found it. Bring your opinions, including the ones that disagree with ours. Infrastructure tooling is changing quickly right now, and we want someone who's paying attention to that as we improve the foundational components that power Hex.

What you will do

• CI/CD: Optimize Hex’s CI/CD pipelines for speed, cost, and flexibility.
• Stack lifecycle: Improve setup, teardown, partial teardown, and updates for single-tenant stacks.
• Postgres at scale: Enhance performance, migrations, and capacity for our multi-tenant production database.
• Cost: Increase infrastructure spend visibility and reduction.
• Security posture: Focus on workload and container isolation, plus compliance work as we move upmarket.
• Platform features: Develop customer-facing infrastructure capabilities, including private connectivity and easier single-tenant deployments.

Qualifications

• 5+ years building and operating production infrastructure, including on-call experience.
• Ability to improve the skills of those around you, regardless of title.
• Strong Kubernetes operations knowledge, including scheduling, networking, and failure modes.
• Solid AWS fundamentals (EKS, RDS, VPC networking, IAM).
• Experience with Infrastructure as code, ideally Terraform.
• Comfortable writing and reading enough application code to change a pipeline, a controller, or a service.
• Ability to turn vague, long-standing problems into shippable solutions without waiting for direction.
• Clear writing skills for design docs and runbooks that engineers outside infra can follow.

Requirements

• Depth in at least one of the following areas:
• Networking: VPC design, private connectivity (PrivateLink, peering), DNS, TLS and certificate management, agentic sandboxing.
• Databases: Postgres at scale, including replication, tuning, connection pooling, major version upgrades, migrations under load.
• Deployment systems: CI/CD platform ownership, build performance and cost, release and artifact management.

Benefits

• Competitive total rewards package, including market-benched salary & equity.
• Comprehensive health benefits.
• Flexible paid time off.

Salary Range

The salary range for this role is: $214,000 - $285,000. Placement in the salary range will be decided upon completion of the interview process, taking into account factors like geographical location, skill ranges/levels, internal fairness & parity, demonstrated skills, and depth of experience.
