Remote Application Developer Jobs in Elizabeth, NJ

About the Company

Gemini is a global crypto and Web3 platform founded by Cameron and Tyler Winklevoss in 2014, offering a wide range of simple, reliable, and secure crypto products and services to individuals and institutions in over 70 countries. Our mission is to unlock the next era of financial, creative, and personal freedom by providing trusted access to the decentralized future. We envision a world where crypto reshapes the global financial system, internet, and money to create greater choice, independence, and opportunity for all - bridging traditional finance with the emerging cryptoeconomy in a way that is more open, fair, and secure. As a publicly traded company, Gemini is poised to accelerate this vision with greater scale, reach, and impact.

The Department: Application Security

Gemini operates at the intersection of financial services and emerging technology where the consequences of security failure are measured in customer trust and regulatory standing. The Application Security (AppSec) team exists to make sure security is never an afterthought. We are on a mission to secure products at the time of thought and the time of build: at the product requirements doc, the technical architectural decision, at the line of code. We believe that security input is most valuable before the work is done and after-the-fact is too late and too expensive.

The Role: Senior Application Security Engineer

As a Senior Application Security Engineer on the Application Security team, you will be a trusted partner to engineering, product, and business teams across Gemini. You will help guide teams to design and build secure products while building systems and culture that embed security judgment into every team. Gemini is AI-first and AppSec builds the tools to make this vision secure.

Responsibilities:

• Lead secure design reviews, threat modeling, code review, and penetration testing for high-risk products such as crypto custody, trading systems, and payments
• Build and ship code: design and build AppSec tooling including AI agents for secure design and code review, AI-enhanced SAST/DAST pipelines, and automation that eliminates repeatable security toil
• Partner with engineering teams to remediate vulnerabilities and drive long-term improvements in secure coding practices

Minimum Qualifications:

• 5+ years of experience in application security or similar roles
• Ability to perform design reviews, threat modeling, secure code reviews, or penetration testing with an attacker mindset
• Experience building or meaningfully contributing to security tooling and automation
• Strong background in application security best practices and familiarity with common vulnerabilities (e.g. SSRF, race conditions, privilege escalations, etc.)
• Some background in development or scripting experience (Python, Scala, C++, or JavaScript) with the ability to read and write code
• Strong communication skills to influence without authority and the ability to collaborate on a cross-functional team with competing priorities

Preferred Qualifications:

• Experience building AI application security tooling using agents or skills
• Experience with supply chain security, common frameworks (SLSA, OWASP SPVS) and other CI/CD security controls
• Familiarity with highly regulated environments (financial services, fintech, crypto, or equivalent) and ability to understand business objectives, business context, and security risk
• Experience with preventing application security vulnerabilities at scale through secure design patterns, automated tooling, or frameworks
• Experience with microservice architectures and cloud-native environments

• Competitive starting pay
• A discretionary annual bonus
• Long-term incentive in the form of a new hire equity grant
• Comprehensive health plans
• 401K with company matching
• Paid Parental Leave
• Flexible time off

Salary Range: The base salary range for this role is between $140,000 - $200,000 in the State of New York, the State of California and the State of Washington. This range is not inclusive of our discretionary bonus or equity package. When determining a candidate's compensation, we consider a number of factors including skillset, experience, job scope, and current market data.

In the United States, we offer a hybrid work approach at our hub offices, balancing the benefits of in-person collaboration with the flexibility of remote work. Expectations may vary by location and role, so candidates are encouraged to connect with their recruiter to learn more about the specific policy for the role. Employees who do not live near one of our hubs are part of our remote workforce. All employees, however, are required to onboard in-person at one of our office locations.

At Gemini, we strive to build diverse teams that reflect the people we want to empower through our products, and we are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity, or Veteran status.
