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.

We’re a remote-first consultancy specialising in software engineering, product design, and data. Our teams are based across London, Lisbon, and Porto, and we create digital solutions that continue to deliver value long after our work is done.

About the role:

As a Senior Data Engineer, you’ll be part of a client team building innovative products. We expect you to be curious, passionate, driven, and enthusiastic. You’ll be proficient at problem-solving, and crafting scalable, resilient, and fault-tolerant architectures. You’ll be an effective communicator and a team player. You and your team will move in a fast-paced engineering environment, achieving outstanding results and delivering exciting projects.

About you:

A YLD Senior Data Engineer is a highly skilled engineer who spans across data engineering and analytics engineering, and knows where the boundaries sit. You've built pipelines and transformation layers. You've inherited messy data projects and made them good. You have opinions about how data teams should work and the humility to adapt them to context.

You have a real passion for the craft and are an active learner who gets excited by the variety that consultancy brings: different clients, different stacks, different problems.

Your day-to-day responsibilities will look like this:

• Delivering data work on client engagements: pipelines, transformation layers, models, and the infrastructure around them
• Adapting to different client contexts, legacy warehouse migrations, greenfield lakehouses, struggling transformation layers that need rescuing
• Defining and evolving our internal standards for data work: testing, documentation, project structure, code review
• Mentoring and growing data engineers across the company
• Showing up for client team moments (internal speakers, learning sessions, social events) to build strong working relationships.
• Contributing to proposals and helping shape engagements during the sales process
• Representing YLD externally through writing, speaking, and contributing to the wider data community.

You’ll have the following skills and experience:

• SQL as engineering: You write SQL that's reviewable, testable, and performs at scale. You understand query planning, engine quirks, and how materialisation choices affect cost and performance
• Python for data: You write typed, testable Python for pipelines and tooling. You've built and maintained production data systems, not just notebooks
• Data modelling: You've made deliberate choices between dimensional, Data Vault, normalised, and denormalised designs. You can explain those trade-offs in terms of flexibility, query performance, and maintainability
• Transformation architecture: You design transformations that are idempotent, incremental, and dependency-aware. You think in DAGs, not scripts
• Pipeline design: You understand batch, streaming, and micro-batch trade-offs. You consider latency, complexity, cost, and reprocessability. And choose the right approach for the problem
• Data testing: You write tests as code, schema contracts, assertions, and transformation logic. You know what to catch at build time vs. defer to observability
• Data observability: You treat data reliability like site reliability. Measurable indicators, alerting, incident response, and root cause analysis
• CI/CD for data: You version, test, and deploy pipelines like software. Environment promotion, rollback strategies, and infrastructure as code for reproducible environments
• Data governance: You've implemented lineage, cataloguing, sensitive data classification, or access control. Not just built pipelines, but made them auditable and secure
• Cost-conscious: You've optimised warehouse spend, storage strategies, or job efficiency. You treat compute as a resource to manage, not ignore
• Platform fluency: You've worked across the modern stack. Orchestration (Airflow, Dagster), warehouses (Snowflake, BigQuery, Databricks), ingestion (Fivetran, Airbyte, custom), and transformation (dbt, Spark)
• Cross-functional fluency: You translate engineering constraints into business terms and negotiate realistic commitments

You’ll be:

• Self-motivated and proactive
• Comfortable with ambiguity, experimentation, and iteration
• Collaborative by default. You work well in teams and across teams
• Analytical and detail-oriented in your approach to problems
• Comfortable context-switching across clients, stacks, and problem types
• Willing to shape engagements, not just deliver them: contributing to proposals, scoping, and client relationships
• Active in the wider data community: writing, speaking, or open-source contribution
• Genuinely committed to diversity, equity, and inclusion

Benefits you'll get:

• Company Private Health care
• Enhanced fully paid maternity and paternity leave for up to 6 months
