We started from scratch by building a completely cloud-native clearing and custody system designed for today’s complex, global market. Our platform is fully integrated with central clearing houses and exchanges to support billions in trading volume per day. We’ve agonized about our data model abstractions, created horizontal scalability, and crafted thoughtful APIs. All so we can provide a best-in-class experience for our clients.

By combining highly-skilled product and engineering talent with seasoned finance professionals, we’re building the essentials to compete in today’s fast-paced markets.

The Team:

Clear Street’s Infrastructure Engineering team builds the foundational stack for our services. It spans multiple disciplines including Core Platforms, Developer Experience, Security, and Data. The team is highly visible and operates horizontally across the entire Engineering organization.

The Role:

We are seeking a seasoned Technical Lead Software Engineer to join our dynamic Infrastructure Engineering team, focusing on enhancing security infrastructure and optimizing developer experience.

In this role, you will be responsible for leading a team of talented engineers, driving the design, implementation, and maintenance of robust security solutions while also ensuring a seamless developer experience across our software development lifecycle. You’ll lead efforts to fortify our software supply chain against vulnerabilities and threats, ensuring the integrity and trustworthiness of our software products. You will also be responsible for designing and implementing solutions for fortifying our runtime environment in AWS and Kubernetes, including automation for AMI hardening and orchestration of OS patches.

You’ll work horizontally across the Infrastructure and Security teams, closely collaborating with Engineering leadership and the company’s CISO to design the Security Infrastructure team’s roadmap. You’ll also draw up technical project designs and execution plans and be involved hands-on in the implementation of these projects. You’ll also advocate for developer-friendly security solutions, providing tools and resources to empower Clear Street’s engineers to make informed security decisions. In doing so, you will champion a culture of security awareness and best practices among developers, promoting a proactive approach to addressing security concerns.

Requirements:

  • At least ten (10) years of professional experience in software engineering, with a focus on software supply chain security.
  • Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
  • Proficiency in programming languages such as Java, Python, or Go, and experience with DevOps tools and practices.
  • Experience with containerization technologies (e.g., Docker, Kubernetes) and cloud platforms (e.g., AWS, Azure, GCP).
  • Experience with Git principles and command line
  • Proven leadership skills, with experience leading and mentoring engineering teams.
  • Excellent communication skills, with the ability to convey complex security concepts to technical and non-technical stakeholders.

Preferred Qualifications:

  • Strong understanding of CI/CD principles and methodologies, with demonstrated experience in designing, implementing, and maintaining pipelines and runner infrastructure, preferably with a CI/CD platform such as GitHub or GitLab
  • Deep understanding of software supply chain security principles, including dependency management, artifact signing, and SBOM (software bill of materials)
  • Familiarity with techniques and tools for SAST (Static Application Security Testing), DAST (Dynamic Application Security Testing) SCA (Software Composition Analysis) and vulnerability management platforms.
  • Familiarity with Security techniques for cloud workload protection (CWPP) and security services in AWS

We Offer:

  • The opportunity to join a small and growing team of good people, where you can make a difference.
  • A meritocratic philosophy that champions collaboration.
  • Competitive compensation, benefits, and perks.

At Clear Street, we offer competitive compensation packages and benefits. Our belief has always been that we are better as a business when we are all together in person. As such, we are requiring employees to be in the office a minimum of three days per week.

Our top priority is our people. We’re continuously investing in a culture that promotes collaboration. We help each other through challenges and celebrate each other’s successes. We believe that modern workplaces succeed by virtue of having high-performance workforces that are diverse — in ideas, in cultures, and in experiences.
