Nice to have, but not essential * Experience working closely with Data Engineering, Data Architecture or analytics teams. * Practical understanding of data modelling, data quality, lineage, data contracts or transformation pipelines. * Experience building reliable ingestion or integration workflows, event-driven services or messaging-based systems. * Familiarity with cloud data platforms such as Snowflake, BigQuery, Redshift or Databricks, or with BI and semantic-layer concepts. * Experience working with multi-tenant systems, row-level access controls, PII or GDPR-sensitive data. * Experience supporting a migration from legacy reporting or BI technology to a governed, modern data platform. You don't need experience with every tool or concept listed above. We're more interested in your engineering fundamentals, problem-solving approach, curiosity and ability to learn. ## Description Our customers rely on Rotageek to support important workforce decisions. As a Software Engineer, you'll help build the services, APIs and integrations that make those experiences reliable, secure and easy to extend. You'll take ownership of well-scoped features and components, turning clear requirements into simple, robust and maintainable C# and .NET solutions. You'll work closely with Engineering, QA, Product and Data colleagues from design through to production. This is a role for an engineer who cares about the whole journey, not just the code. You'll think about testability, security, performance, observability and the way application data moves into reliable customer-facing experiences. You'll also use AI-assisted engineering tools as part of your delivery workflow. You'll use them to accelerate implementation, testing and refactoring, while applying your judgement to validate the output for correctness, security and architectural fit. ️ What you'll be doing * Break down well-scoped features into deliverable tasks, identifying dependencies and communicating progress, risks and decisions. * Design medium-complexity components with clear responsibilities, well-defined interfaces and sensible separation of concerns. * Write automated tests covering core behaviour and common edge cases, working with QA to ensure the right coverage at the right level. * Apply established security practices, including OWASP principles, secure handling of data and appropriate escalation of risks. * Use logs, metrics and traces to monitor, troubleshoot and improve production behaviour. * Participate in constructive code reviews that improve logic, style, performance and security while helping colleagues grow. * Work with Data Engineering colleagues on interfaces, data contracts, data quality and operational failure modes. * Contribute to incident response, post-incident learning and continuous improvement of the services you support. * Document technical decisions and operational knowledge so the team can understand, support and extend what you build., * You use AI-assisted delivery thoughtfully, validating generated code and tests before they become part of the product. * You favour simple solutions, evaluate existing libraries and services before building new ones, and avoid unnecessary complexity. * You take ownership from ticket to production, including documentation, testing, monitoring and follow-through. * You are comfortable explaining technical choices, listening to alternatives and collaborating across Engineering, QA, Product and Data. * You connect implementation decisions to customer value, reliability, cost and the wider product experience. * You share knowledge through pairing, reviews and clear documentation, while asking for help early when a problem needs wider input. The impact you'll make * Customers receive reliable features that are easy for the team to understand and extend. * Components have clear boundaries, sensible abstractions and automated coverage. * Production issues are diagnosed quickly because the right signals and documentation are in place. * The team can trust your delivery, your reviews and your communication. * Application and data integrations have clear ownership, interfaces and failure behaviour. * Data-dependent features work coherently from source system through to analytics and customer experience. The tools and ways of working * C# and .NET for services, APIs and application development. * Strong SQL and relational data stores, with an interest in how application data becomes reliable analytics data. * Automated unit and integration testing, Git, CI/CD and environment-aware delivery. * Observability through logging, metrics, tracing and production diagnostics. * Cloud-hosted services, with AWS experience useful in our wider platform environment. * AI-assisted engineering tools such as Claude Code or Codex, used with disciplined review and validation. * Agile planning, code review, incident response and collaborative technical documentation. ## Related Videos - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Data Science in Retail](https://www.wearedevelopers.com/videos/586-data-science-in-retail) - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [How building an industry DBMS differs from building a research one](https://www.wearedevelopers.com/videos/768-how-building-an-industry-dbms-differs-from-building-a-research-one) - [Modern Data Architectures need Software Engineering](https://www.wearedevelopers.com/videos/1030-modern-data-architectures-need-software-engineering) ## Related Articles - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
