Platform Engineering at Capital On Tap 🚀

The Platform Engineering team powers fast, secure, and reliable software delivery across the business. We partner with Engineering, Data, Security, and QA teams to build platforms that reduce toil and make engineers' lives easier. From managing our Azure infrastructure and CI/CD pipelines to shaping core developer tooling, we focus on scalability, resiliency, and security at every step. We're always exploring new tools, testing ideas, and applying industry best practices to keep our platform cutting-edge and our teams empowered.

What You'll Be Doing 🗃️

• Develop a deep understanding of how infrastructure changes differ from application changes, and become a subject matter expert in the unique challenges of testing them safely and effectively.
• Define and own the frameworks, processes, and guardrails that ensure infrastructure changes are validated consistently across all environments  from development through to production.
• Build and maintain automated validation pipelines that verify infrastructure changes at each stage of promotion, catching drift, regressions, and misconfigurations before they reach production.
• Establish clear standards for what "good" infrastructure testing looks like at Capital on Tap covering areas such as plan validation, policy compliance, integration testing, and rollback verification.
• Design, provision, and maintain dedicated test environments on Azure, ensuring they are stable, reproducible, and closely mirror production.
• Own the Infrastructure as Code (Terraform) for all test environment provisioning, teardown, and configuration management.
• Collaborate with QA and Product Engineering teams to understand environment requirements and translate them into reliable, scalable infrastructure.
• Develop and enforce standards around test data management — including data seeding, masking, and refresh strategies to support consistent and repeatable testing.
• Monitor the health and availability of test environments using existing observability tooling, proactively identifying and resolving issues before they block teams.
• Contribute to incident management processes, ensuring infrastructure-related failures are diagnosed quickly and learnings feed back into improved guardrails and processes.

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 🔎

• 2-4 years of experience in a platform, DevOps, or infrastructure engineering role, ideally with some exposure to QA, testing practices, or quality engineering.
• A genuine curiosity for understanding how infrastructure changes behave differently to application code changes, and an interest in building the processes to test them rigorously.
• Hands-on experience with a major cloud provider (Azure, AWS, or GCP), with the ability to design and manage non-production environments.
• Proven experience writing and maintaining Infrastructure as Code (Terraform), including an understanding of plan/apply workflows and how changes can be safely validated.
• Familiarity with policy-as-code, compliance validation, or infrastructure testing approaches (e.g. validating configurations, detecting drift, or verifying rollback behaviour).
• Solid understanding of containerisation and Kubernetes, particularly in the context of running isolated, ephemeral test workloads.
• Familiarity with CI/CD pipelines and how infrastructure change validation fits into automated delivery workflows.
• Comfortable working with observability and alerting tooling to monitor environment health and surface issues early.
• Proficiency in at least one scripting language (Python, PowerShell, or Go) for automation and tooling tasks.
• Strong communication skills and a collaborative approach, you'll be working closely with platform engineers, QA engineers, and security teams to establish shared standards.

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

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.

• 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.

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.

🏢This is a Hybrid role, working from our Porto (Matosinhos) Offices 2 days per week.

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
