There's a guideline in medicine called "Sutton's Law": first consider the obvious. The law gets its name from an apocryphal interview with Willie Sutton, an infamous bank robber, who was asked "Why do you rob banks?" and replied simply "Because that's where the money is."

Mercury is building the banking* stack for startups, and it's obvious security is critical to our product. That's where the money is.

At Mercury, there are two dedicated security teams. The first is a comprehensive Information Security (InfoSec) team with extensive backgrounds in security. They focus on areas such as PCI/SOC2 compliance, endpoint management, detection and response, as well as network and corporate security. This team has a wide mandate and frequently work in our product and infrastructure as well. 

The team you would be joining is primarily focused on engineering, with a primary goal of addressing security challenges through code. Our work involves tackling a variety of security issues, ranging from developing security features to creating infrastructure that assists other teams in building their features securely. Currently, our main projects include enhancing our admins' permissions system, devising a streamlined method for users to verify their identity during phone calls, and a few smaller initiatives. In addition to coding, we actively engage with other teams. This involves explaining vulnerabilities identified through our bug bounty programs, addressing security concerns related to ongoing projects, and responding to queries from other teams. Exceptional security judgment, a grasp of product concepts, and effective communication skills are highly valuable in these collaborative scenarios.

As a Security Engineer at Mercury, you will:

  • Address key security features within the product, such as developing passkey support, enhancing the security dashboard, refining user-facing audit logs, and implementing SAML.
  • Upgrade our pentest environment to ensure it aligns with our security researchers' needs, addressing challenges like data sufficiency and effective stubbing of third-party interactions.
  • Contribute to bug bounty program triage by validating reports, coordinating responses, and managing researcher payments, while collaborating with teams to resolve identified issues.
  • Analyze vulnerabilities and proactively target root causes by creating tools for codebase scanning, establishing effective patterns and systems, and enhancing security training for engineers.
  • Assist teams in threat modeling and cultivating a security mindset for their features, leveraging dedicated security expertise to complement the existing skills of our engineers.
  • Investigate user security issues, utilizing product knowledge and logs to understand incidents and proposing improvements to monitoring for quicker detection of similar issues.

The ideal candidate possesses:

  • Excellent empathy for customers.
  • An ability to carefully consider tradeoffs between security and user experience.
  • Proficiency in standard software engineering, including discussions on schema and app design.

Requirements:

  • Three or more years of experience in software security roles or equivalent.
  • Full-stack development experience, with excitement to learn and work with Haskell, React, and TypeScript.

Nice to Haves:

  • Familiarity with our tech stack.
  • Experience in fraud or finance-related domains.

The total rewards package at Mercury includes base salary, equity (stock options), and benefits.

Our salary and equity ranges are highly competitive within the SaaS and fintech industry and are updated regularly using the most reliable compensation survey data for our industry. New hire offers are made based on a candidate’s experience, expertise, geographic location, and internal pay equity relative to peers.

Our target new hire base salary ranges for this role are the following:

  • US employees (any location): $203,100–$238,900.
  • Canadian employees (any location): CAD 184,800–217,400.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
