Senior QA Engineer

About InvestEngine

We’re a London-based fintech on a mission to make ETF investing simple and accessible. Over 130,000 clients have trusted us with over £2 billion in assets — and we’re just getting started. We’ve been featured by Forbes, MoneyWeek, and Finder, and we’re growing fast with big ambitions.

About the Role

We’re looking for a Senior QA Engineer to join our Backoffice team , working on business-critical internal systems with strict financial and compliance requirements. The team is responsible for client money controls (CASS) and for migrating internal admin tools to a new interface, with a strong focus on backend systems and data integrity.

You’ll collaborate closely with engineers, product managers, and stakeholders across teams. In this role, you’ll take real ownership of system-level quality — shaping test design, identifying risks, and improving QA processes. This is a great fit for someone proactive and detail-oriented, who thinks beyond automation and is comfortable working in a complex, cross-functional environment.

What You’ll Do

• Manually test product features with a primary focus on backend functionality (~70%), including APIs, integrations, and data flows, and a secondary focus on frontend (~30%)

• Collaborate closely with developers and product/marketing stakeholders to clarify requirements, edge cases, and acceptance criteria

• Proactively identify quality gaps, propose improvements, and contribute to the continuous evolution of QA processes

• Perform API testing using Postman (basic to intermediate level)

• Write and execute simple SQL queries to validate data consistency and business logic

• Use proxy tools to inspect and validate complex request/response flows when needed

• Support regression testing for mobile applications on an as-needed basis

What We’re Looking For

• 3+ years of manual QA experience, focused on web applications

• Solid knowledge of test design techniques

• Hands-on experience testing APIs and working with Postman

• Technical literacy: HTML/CSS, client-server architecture, and basic debugging

• Ability to write SQL queries to validate backend logic

• Confident using proxy tools like Charles or Fiddler

• Strong critical thinking and analytical skills — not just following test scripts

• Self-driven, organized, and comfortable working without micromanagement

• Clear communicator who collaborates well with tech and non-tech teams

• English (B2 level or higher) and fluent Russian

Nice to Have

• Experience testing mobile apps (Android/iOS)

• Interest in building or improving QA workflows and processes

• Familiarity with automation tools or AI-assisted testing (not required, but a plus)

• Previous experience in product-first companies or marketing-driven environments

How We Work

We’re a lean, fast-moving team that values clarity, ownership, and continuous improvement. You’ll be more than just a ticket-tester — you’ll help shape how we build, ship, and maintain quality across the product.

We expect initiative, not just execution. At the same time, you’ll have support from experienced QA leads and an open, collaborative culture that encourages experimentation and learning.

What We Offer

• Impact from day one
  You’ll help ship critical features used by tens of thousands of customers.

• Room to grow
  You’ll have the chance to expand your scope — from owning areas of testing to helping shape team-wide QA practices.

• Modern tools
  You’ll work with Postman, SQL, and more. And if something’s missing — help us find and adopt it.

• Transparent and open culture
  We believe in async-first communication, clear ownership, and team visibility.

• Supportive team
  You’ll collaborate with thoughtful, motivated people across engineering, product, and marketing.

• Remote and flexible
  We care about outcomes, not location. Work from where you’re most productive.
