About the role

You'll be our first dedicated information security hire. Right now security is a part-time job for engineering leadership and external vendor; we want it to be your full-time one. The work is hands-on: AWS, infrastructure as code, detection and response, auditors. As the company grows, the role grows into CISO.

We sell to financial institutions, and their security teams question everything we do, so you'll be the person with good answers.

Tasks

What you'll do

Own security in our AWS environment: IAM and least privilege, network segmentation, encryption, logging and detection (GuardDuty, Security Hub, CloudTrail), fixing what you find.
Build security into the development pipeline: secrets management, dependency and container scanning, code review for risky changes, threat modeling with the engineers.
Automate. Detection rules, alerting, compliance evidence, IaC guardrails. If a control can be code instead of a meeting, make it code.
Run vulnerability management and incident response. Write the runbooks, run the drills.
Set the rules for our AI and LLM use: which data goes to which vendors, which models are approved, how prompts and outputs are handled and logged. Assess risks like prompt injection and data leakage, design controls that let people keep working.
Own SOC 2: control design, automated evidence collection, the auditor relationship.
Handle regulatory side for our financial-institution customers: GDPR and CCPA for privacy, DORA and EBA outsourcing guidelines in the EU, GLBA and SEC/FINRA expectations in the US.
Lead customer security reviews: due diligence questionnaires, RFPs, contract security terms, calls with bank security teams.
Run vendor reviews and third-party risk.
Secure the human half by building awareness training, phishing resilience, and device and identity hygiene that work for deals and sales people, not only engineers.
Over time: set the security strategy, report risk to leadership in business terms, choose tooling, build a budget, hire.

Requirements

What we're looking for

5+ years in security engineering or security-heavy infrastructure work, with depth in AWS security (IAM, SCPs, logging, detection, encryption). Certifications are fine, but shipped work is better.
Python and Terraform, or close equivalents. You automate evidence collection instead of maintaining spreadsheets.
SOC 2 experience, ideally owning a Type II audit. Working knowledge of privacy legislation.
Exposure to financial-services customer scrutiny, or the appetite to make it your specialty.
A working view on LLM security risks, or strong fundamentals and the curiosity to build one.
Judgment about which risks matter. You can tell an auditor why a control exists and an engineer why it isn't theater.
Clear writing. Remote means async, and async means your policies and risk memos do the talking.
The ambition to grow into an executive role and the people skills to survive it.

Nice to have

Fintech or another regulated B2B environment with large financial-institution customers.
DORA, EBA/ESMA outsourcing guidelines, or NYDFS 500.
Experience securing enterprise integrations: SSO/SCIM, SFTP feeds, APIs.
You've been the first security hire somewhere before.

Benefits

What we offer

A blank slate with real ownership
A committed path to CISO.
Fully remote, flexible hours.
Direct access to leadership and to customer security teams at major financial institutions.
Competitive pay, equity, learning budget.

How we hire

Intro call (30 min).
Technical deep dive (60–90 min): AWS security scenarios, plus a walk-through of a program you built.
Practical exercise: review a sanitized architecture or a due diligence questionnaire and tell us what you'd fix first.
Leadership conversation: the CISO path, and working with the non-technical half of the company.
References and offer.

We're an equal opportunity employer. If you don't tick every box, apply anyway.
