Job description

Clear Street is modernising the brokerage ecosystem. Founded in 2018, Clear Street is a diversified financial services firm replacing the legacy infrastructure used across capital markets.

We started from scratch by building a completely cloud‑native clearing and custody system designed for today’s complex, global market. Clear Street’s proprietary prime brokerage platform adds significant efficiency to the market, while focusing on minimising risk, redundancy, and cost for clients. Our goal is to create a single source‑of‑truth platform for every asset class, in every country, and in any currency.

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

The Role

As an experienced Frond‑end Software Engineer you will help build our flagship Clear Street Studio, a modern prime brokerage experience. You will tackle non trivial problems that force you to balance trade offs while implementing clean and efficient solutions. You will raise our bar on providing clean and efficient solutions that delight and offer the best experience for our customers. You will push our operational standards and ensure that we are able to offer and maintain a high SLA.

This role is deeply involved with engineering the next generation of our state of the art Studio (portal) for our varied client base including hedge funds, traders and portfolio managers.

• You have 7+ years of professional experience building web applications with React and TypeScript.
• You’ve helped build systems that solve complex business problems and process huge volumes of data, and you’re naturally interested in scale, distributed systems, and the technologies around them.
• You’re able to clearly articulate system design trade‑offs and patterns to both engineers and non‑technical stakeholders.
• You put the end user first, which is reflected in the way you design APIs, as well as in your features’ functionality and performance.
• You have a solid grasp of design patterns, data structures, and algorithms.
• You communicate technical concepts clearly and enjoy collaborating with others to ship high‑quality products.
• Your experience enables you to mentor teammates, help define engineering best practices, and promote a systems‑design mindset when creating new services.

The Team

You will work with a team of talented, passionate and highly collaborative engineers. Working together, we have built a platform that serves institutional clients and is at the forefront of technological innovation. Our engineers take pride in not just the value we provide our customers but the quality of our work. As a member of our team, you will have the opportunity to work with cutting‑edge technologies, collaborate with colleagues from diverse backgrounds, and make a meaningful impact on the financial industry. We value creativity, innovation, strong work ethics, and we are committed to providing our team members with the support and resources they need to succeed.

Requirements

• Minimum of seven (7) years of professional experience building scalable web applications.
• At least five (5) years of hands‑on experience with, and strong understanding of, front‑end technologies such as React and TypeScript.
• Proven ability to identify and resolve performance bottlenecks.
• Deeply focused on delivering exceptional user experiences.
• Enjoy collaborating in a team‑first, highly cooperative environment
• Take pride in producing high‑quality work and consistently hold yourself to a high standard.

We Offer

At Clear Street, we offer competitive compensation packages, company equity, pension, gender neutral parental leave, and full medical and dental insurance. 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. We put in the effort to make such a workplace a daily reality and are proud to be an equal opportunity employer.
