About this role
About PointOnePointOne 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.
The RoleLet’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.
What You'll OwnInfrastructure 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
What We're Looking For5+ 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.
Why This Role MattersA 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!
