Security Infrastructure Engineer

PointOne builds infrastructure for the legal industry, powering timekeeping and billing systems used by law firms and government agencies.

We build and operate systems that process the most confidential data for institutions working on the most sensitive matters. Security for us is a strategic priority.

We’re hiring a senior engineer to own the security, scalability, and cost efficiency of our AWS environment.

Let’s start with what this isn’t:

Not a GRC or paperwork-heavy compliance role

Not a vulnerability-scanning-only position

Not a “turn on GuardDuty and call it done” role

You will be shaping critical systems and making architectural decisions that materially affect risk and resilience.

This is a hands-on engineering role at the intersection of security, cloud architecture, and platform optimization.

You will harden our AWS infrastructure, reduce blast radius, eliminate unnecessary exposure, and ensure our systems scale efficiently and securely.

Infrastructure Security

Design and enforce least-privilege IAM across services

Implement permission boundaries and SCP strategy

Reduce attack surface across networking and service exposure

Improve secrets management and KMS key segmentation

Lead threat modeling across core systems

Design blast-radius containment strategies

Detection & Response

Strengthen logging, monitoring, and anomaly detection

Ensure logs are immutable and auditable

Build and test incident response playbooks

Review new infrastructure designs for security risks

Scale & Cost

Optimize AWS architecture for reliability and efficiency

Improve Lambda/SQS concurrency and scaling patterns

Evaluate and improve RDS scaling strategy

Drive principled tradeoffs between isolation, performance, and cost

5+ years operating AWS infrastructure in production

Deep IAM expertise (roles, policies, trust relationships, STS)

Strong AWS networking knowledge (VPC, PrivateLink, Security Groups)

Experience designing multi-account AWS environments

Hands-on experience responding to real security incidents

Strong understanding of cloud attack vectors and privilege escalation

Experience reducing cloud cost without compromising security

Comfortable working directly in CDK/Terraform and reviewing infrastructure code

Strong plus: Experience in legal, fintech, government, or other high-sensitivity environments.

A security breach at PointOne would have consequences extending far beyond the survival of our company. This role exists to:

Protect sensitive institutions

Raise the engineering bar on secure system design

Build infrastructure that enterprise and government customers can trust

You will be a core architect of PointOne’s long-term security posture.

This is intense early-stage startup work. You will be expected to take ownership, bring structure to ambiguity, and build the connective tissue between our customers and our product.

The compensation for this position is determined by multiple factors, including prior experience and expertise. A competitive equity component will also be offered as part of the package. Benefits include comprehensive health, dental, and vision insurance, as well as meals in office, regular team events, and more!
