Job description

We are looking for a Senior TypeScript Engineer with strong Kubernetes experience to join our Engineering team at Valstro. Our goal is to build scalable, cost-efficient, and maintainable services using modern software development practices.

Valstro is an ambitious FinTech partnership on a mission to redefine trading technology for global, multi-asset class institutional clients. Whether you see us as a startup or a "baby enterprise," one thing is clear: we are a people-first company. Our success is built on the talent, collaboration, and motivation of our team.

We're not just building software—we're engineering highly modular, well-tested, well-documented, and easily discoverable applications. This approach isn’t just good practice; it’s our not-so-secret sauce for scaling both our product and our business.

At Valstro, we're here to shake up an industry that’s long overdue for tech-driven disruption. As we expand our capabilities and reach, we aim to push the boundaries of what’s possible, challenging outdated industry norms at every turn. Our clients deserve better—and we're here to make it happen. If that vision excites you, keep reading.

What will you be doing?

• Enhancing/expanding existing applications and services, as well as contributing to the development of new ones.
• Participating in architecture discussions, technology selection, and design to deliver high-quality software.
• Building, testing, deploying, and maintaining stable, resilient and performant software.
• Collaborating across teams to: refine processes, improve tools, and deliver impactful solutions.
• Continuously improving your skills, staying up to date with the latest technologies, and actively sharing knowledge and best practices with the team.

The ideal candidate has:

• Extensive experience building enterprise-level software with TypeScript.
• Hands-on expertise in Kubernetes and containerized microservices architectures.
• A deep understanding of cloud-native development, CI/CD pipelines, and distributed systems.
• Passion for delivering high-quality, performant software in a collaborative team environment.

What you need to bring

A good portion of the following:

• Real-world experience developing production systems in TypeScript, including the use of popular frameworks and libraries.
• Expertise in CI/CD pipelines, with hands-on experience using GitHub Actions/Workflows and other industry-standard tools.
• Experience building multi-threaded/concurrent applications.
• Experience working in a Linux environment (CentOS, RHEL, Ubuntu etc. - any flavor is ok)
• Hands-on experience with containerized environments, particularly Docker and Kubernetes.
• Practical use of SQL databases.
• Experience working with messaging queues (Kafka, JMS, RabbitMQ, EventHub etc.).
• Bonus: Experience with Nx for monorepo management.
• Bonus: Experience developing systems for Equity Trading in Capital Markets.

What is the Environment like at Valstro?

Valstro was founded during the COVID-19 pandemic and has operated on a remote-first basis ever since. However, as the world returns to normal, we also recognize that certain types of knowledge work benefit immensely from in-person collaboration. To support this, we established our physical office in Midtown NYC three years ago, providing a dedicated space for teams to connect and collaborate.

We are a distributed team, with staff in the UK, the NYC area, and across the US.

While remote work remains a core part of our culture, NYC-based employees are expected to take advantage of the Midtown office space and collaborate in person on a regular basis.

Regardless of location, Valstro is a fantastic place to work.

Valstro offers an excellent benefits package, including pension plans, flexible time off and highly competitive compensation. Our leadership team brings a wealth of experience and deep industry knowledge, and despite being a young company, we believe we have carefully dialed in our product-market fit. As we move forward in executing our vision for clients, the Engineering team is looking for client-obsessed, delivery-focused high performers (with a healthy dose of humility)—future FinTech leaders ready to make an impact.

If this excites you, we’d love to chat!
