Original job description

Citian is a fast growing, venture backed SaaS technology company based in Washington, DC. Our software solutions revolutionize how our transportation and infrastructure systems – roads, rail, transit, bicycle, pedestrian – operate.

Our tech solutions:

Reduce traffic fatalities
Enhance pedestrian accessibility
Empower system operators to save time & money

You’ll work with some of the brightest minds in the software and transportation industries. Our engineers and data scientists apply the latest in emerging tech, Artificial Intelligence, and Machine Learning to build smarter, more advanced tools for our diverse client base. We work with clients across the United States, with global ambitions in the years ahead.

Who You Are:

You're a hands-on security engineer who has secured production cloud systems against regulatory or contract requirements, and you know what an assessor will ask for. You set the standard, write infrastructure code, review changes, and help teams fix problems rather than handing them a list. You can explain risk and trade-offs clearly to engineers, executives, and our customers' security teams.

You'll work with engineering and company leadership to secure systems that public agencies rely on, set our security standards, and help us expand to more states.

Expected Duties:

Lead security and compliance across our products: crash analytics, asset management, and crash data intake for state agencies. Work with engineering and data teams to set requirements, build controls, track fixes and prepare for audits and assessments.
Secure our crash data intake product, which handles criminal justice information in AWS GovCloud, in a way we can repeat for each new state: identity and MFA, encryption and key management (including FIPS where required), network isolation, logging and alerts, backup and recovery, retention and deletion, and limits on what data can leave.
Set and enforce access controls for regulated customer data, including contract limits on access from outside the US and through third-party tools, with the engineering and data teams that run those systems.
Turn customer contracts and security frameworks, such as SOC 2 and CJIS, into specific controls, each with an owner, a check (automated where possible) and current evidence. Support independent assessments that contracts require, such as against NIST SP 800-53 Moderate.
Be the technical contact for our customers' security and compliance teams, with Customer Success: questionnaires, architecture reviews and audits.
Run how we find and rank vulnerabilities across infrastructure, code and dependencies. Work with the teams that own those systems to prioritize fixes, confirm them and track exceptions.
Set up security monitoring and incident response, and practice it with the engineering on-call team.
Write security standards for engineers and AI coding agents, and build checks into how we develop and deploy.
Decide when we need outside help, such as assessors, penetration testers or managed services, and lead that work.

Required Skills & Experience:

Bachelor's degree in Computer Science, Information Security, or a related field, or equivalent experience
6+ years in security, platform or infrastructure engineering, with a strong security focus in AWS
Has secured production systems against defined requirements, including building controls, keeping evidence and supporting independent assessments
Infrastructure as code (for example, AWS CDK or Terraform) and core AWS security (IAM, KMS, networking, logging)
Application and data security, including keeping customers' data separate and authorization; working knowledge of TypeScript, JavaScript or Python
Has investigated and responded to production security incidents
Has worked directly with customer security or compliance teams
Uses AI coding tools in daily work, checks their output, and keeps sensitive data out of unapproved AI services

Preferred Qualifications:

CJIS, AWS GovCloud, FedRAMP, GovRAMP (formerly StateRAMP) or NIST SP 800-53 assessments, especially for state or local government
SOC 2 Type 2, including compliance tools such as Drata
Protecting personal data in data pipelines, including AI processing
Identity providers such as Auth0, Okta or Amazon Cognito
Transportation or public safety data
Security certifications, such as AWS Security Specialty or CISSP

Location and screening:

This job must be done from within the United States. Access to some customer systems and data requires agency background screening, including fingerprint-based checks, and ongoing security training.

Salary Range: $150,000 - 200,000 base salary

Your Citian Advantage:

Competitive salary and benefits package including medical, dental, and vision insurance and generous PTO.
401(k) company match and monthly commuter transportation benefit
On-site gym and free snacks in the office
High-growth potential and opportunities for advancement within a fast growing, venture-backed SaaS startup!
