Job Description

We're looking for an SDET or a Software engineer with a taste for quality who's ready to level up their career and make a real impact to join our team at Valstro. Our goal is to build scalable, cost-efficient, and maintainable services using modern software development practices - and that means quality is non-negotiable.  

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.

As an SDET, you'll work alongside our engineering team to build and expand our testing infrastructure, ensuring our financial products are reliable, secure, and scalable. This isn't a manual QA role - you'll be writing code, learning new frameworks, and helping embed quality throughout our development lifecycle. 

In fintech, bugs aren't just annoying - they cost real money and erode trust. We need someone who's excited to grow their skills while helping us maintain the high bar our customers expect. 

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 As we expand our capabilities and reach, we aim to push the boundaries of what's possible, challenging outdated industry norms at every turn.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?  

• Collaborate with product and engineering teams to understand features and develop appropriate automated tests.

• Write clear, maintainable test automation code in TypeScript using a bespoke in-house solution wrapping playwright. 

• Maintain and extend the bespoke testing framework to support automated tests. 

• Help identify and document bugs, working with developers to resolve issues quickly. 

• Participate in code reviews to catch potential issues early.

• Learn from senior engineers and contribute ideas for improving our testing practices.

Requirements

The ideal candidate has:  

• 2-4 years of experience in SDET, or software development roles.

• Solid programming fundamentals in TypeScript/JavaScript. Functional programming a plus.

• Ability to debug and troubleshoot problems across the stack. 

• Experience writing automated tests. Familiarity with at least one test automation framework (Selenium, Playwright, Cypress, etc.).

• Comfortable working with APIs, both REST and GraphQL endpoints. 

• Basic understanding of CI/CD concepts and tools, networking, monorepos, distributed services architecture, Docker and containers. 

• Passion for delivering high-quality, performant software in a collaborative team environment.  

• Curiosity and eagerness to learn new technologies and testing approaches.

• Strong communication skills for our remote-first environment - you can explain technical concepts clearly in writing.

• Self-motivated and comfortable asking questions when you need help. 

A good portion of the following:  

• Any fintech or financial services experience.

• Fluent use of terminal environments and Windows Subsystem for Linux (WSL) for day-to-day development and testing activities.  

• Bonus: Experience with Loki/Tempo/Grafana for system monitoring and test result analysis.  

• Bonus: Experience developing testing frameworks for Equity Trading systems in Capital Markets.  

Personal Qualities We Value  

• Curious: Natural inquisitiveness and desire to understand how systems work - and how they might break.  

Benefits

Valstro offers an excellent benefits package , including pension or 401 (k) plans, unlimited PTO 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!
