QA at Capital On Tap 🚀

Our QA team thrives on a culture of shared success, where every voice helps shape the quality of our products. Rather than working in isolation, we are fully integrated into diverse product squads, ensuring that everyone is a valued technical partner. The team is currently driving an "automation-first" testing strategy. It’s a collaborative, supportive environment where we prioritise learning from each other and ensuring that everyone has the opportunity to thrive and grow.

What You'll Be Doing 🗃️

• Own manual and automated testing across the SDLC, working closely with Software Engineers and Product Managers to ensure product quality.
• Contribute to and expand automated test coverage within an agile team.
• Drive continuous improvement through POCs, refining QA processes, tools, and best practices.
• Investigate user-reported issues, perform hands-on technical testing, and create, manage, and track bug reports.
• Develop deep product and domain knowledge, supporting engineers and promoting shared responsibility for quality.
• Effectively prioritise work, manage risks, and escalate issues in a fast-paced environment.

Our Values & Culture 🌞

• Just Pilot: We never settle for “good enough”. We pilot new ideas fast, ask questions to figure it out, and scale quickly.
• Why Not Today? Fast is as slow as we go - speed and simplicity gives us a competitive advantage.
• Be a Buddy: We tap in from day one to help the team, we do the right thing even if it’s hard.
• Owners and Dates: We don’t chase people. If you own a task and agree to a date, the expectation is that it gets done.
• Feedback: We want our employees to flourish, so we regularly provide direct and constructive feedback.

We’re Looking For 🔎

• QA experience across web/mobile applications, covering functional, regression, performance, exploratory, manual, and automated testing.
• Understanding of end-to-end impact, risk, dependencies, and pragmatic bug prioritisation to inform QA strategy.
• Hands-on experience with test automation tools and frameworks (e.g. Selenium, Appium, Postman, RestSharp, xUnit/NUnit) and REST API testing.
• Proficiency in C# (or similar OOP languages) and JavaScript/TypeScript, with solid SQL Server querying and scripting skills.
• Experience working in CI/CD environments, implementing continuous testing practices across multiple teams.
• Highly detail-oriented, methodical, and proactive, with a strong bias for problem-solving, exploratory testing, and taking initiative.

Even if you don’t have all of the necessary skills, we still encourage you to apply.

What You’ll Be Doing 

We're looking for an Engineering Team Lead to lead one of our product engineering teams here at Capital on Tap.

This is a people-first leadership role. You'll be responsible for the growth, wellbeing, and performance of a team of engineers, while staying technically credible enough to shape direction, remove blockers, and raise the bar on quality. You won't be the best coder in the room you'll be the person who makes the whole room better.

If you're an experienced Team Lead Engineer looking to own a team in a scaling fintech, this role is built for you.

What You'll Own

Your team. Hiring, developing, and retaining engineers. Running 1:1s that actually matter. Spotting who's ready to grow and creating the space for them to do it.

Delivery. Partnering with Product and QA to plan and ship reliably not by micromanaging, but by removing obstacles, managing risk, and keeping the team focused on what matters.

Culture. Setting the tone for how the team communicates, gives feedback, and holds itself accountable. Building psychological safety without sacrificing standards.

Technical credibility. You won't be heads-down in the codebase every day, but you'll understand the trade-offs your team is navigating architecture decisions, technical debt, build vs buy and contribute meaningfully to those conversations.

What We're Looking For

Leadership first. You've managed engineers before and have a point of view on what good looks like. You know how to have hard conversations, give developmental feedback, and motivate people.

Technical foundation in .NET. Our backend is C#/.NET Core and you'll need enough depth to earn trust with your engineers, review decisions, and spot risks. You don't need to be across every layer of the stack you need to be honest about what you know and curious about what you don't.

Product mindset. You think about engineering in the context of business outcomes, not just technical correctness. You can push back on scope, advocate for quality, and translate between engineering and non-technical stakeholders.

Comfort with ambiguity. Capital on Tap is growing. Priorities shift. We want someone who creates clarity for their team rather than waiting for it.

Nice to Have

• Experience with Azure cloud development
• Familiarity with React or other frontend frameworks
• Background in financial services or fintech
