Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Software Engineer - Founding Team - **Company:** Ebury - **Location:** Valencia, Spain (Remote available) - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Continuous Integration, Data Structures, Software Design Documents, Programming Tools, Strategies of Testing, Technical Debt, Information Technology, Programming Languages - **Published:** August 4, 2026 - **Apply:** https://www.jobleads.com/es/job/eab52ef7a6db832793ff8d88eb6f6a3e6 ## About the Role * Strong technical foundation in computer science or a closely related discipline, gained through formal education and/or equivalent industry experience, with evidence of continuous learning and technical depth. * Extensive experience building and operating production systems at scale. While this often aligns with 10+ years in industry, we value demonstrated impact, sound judgement, and leadership over tenure alone. * Deep understanding of core computer science concepts - including data structures, algorithms, system design, and complexity trade-offs and the ability to apply them pragmatically to real-world, high-scale problems. Proven ability to design, write, and evolve high-quality software in one or more modern programming languages, with a strong focus on maintainability, performance, and operational robustness. * Exceptional problem-solving and analytical skills, able to decompose ambiguous, multi-dimensional problems and drive them to clear, effective technical outcomes. Strong communication and influencing skills, capable of articulating complex technical ideas clearly, building alignment across teams, and constructively challenging assumptions at all levels. * A collaborative, leadership mindset, with a track record of mentoring engineers, raising technical standards, and contributing positively to engineering culture beyond individual delivery., You ask why a feature exists before how to build it, and you're curious about the users and the metrics behind it. * You reason about trade-offs holistically - client value and business context, not only the code. * You're pragmatic about scope: you know the difference between an MVP that teaches you something and gold-plating that doesn't. * You're comfortable making a product call without a fully-specified ticket, and changing your mind when the data says so. * You're AI-native: AI coding tools are already part of how you work and you get measurably more done with them; bonus if you've shipped AI features into a product and have a view on where they help the user and where they don't. * You care about quality because you've handled money-adjacent systems, or you're the kind of engineer who would: correctness, reliability, and the un-glamorous finish-and-tidy that keeps a codebase healthy. * Working English (our engineering language); * Nice to have: fintech / payments / regulated-domain experience; the other of web/mobile; experience being early at a new office or founding team. ## Description * Days 1-30: ship your first change to production in the first few days (we pre-scope it and pair you with a buddy), learn the domain, own a small feature end to end. * By 90 days: own a defined product area, lead a project with a short design doc, join the on-call rotation for what you build, and start mentoring the next hire. * Across the year: take client problems from ambiguous idea to shipped, measured, iterated product; help set the standards, interview bar, and culture for a hub that's growing around you. What Your Responsible For * Provide technical leadership across one or more critical domains, owning the design and evolution of large-scale, business-critical systems within our global financial platform. * Set architectural direction by leading system design, making high-leverage technical decisions, and driving alignment on long-term technology strategy across teams. Partner closely with Product, Design, and Engineering leadership to translate business outcomes into scalable, resilient technical solutions, influencing roadmap decisions and trade-offs. * Operate across the full system lifecycle, from early discovery and architecture through to production operations, reliability, performance, and cost optimisation. Raise the technical bar organisation-wide by defining and evolving engineering standards, guiding design reviews, and mentoring senior engineers to multiply impact beyond your own code. * Act as a force multiplier by identifying systemic risks, technical debt, and cross-team dependencies early, and proactively driving initiatives that improve velocity, quality, and resilience at scale. * Champion engineering excellence through strong opinions on testing strategies, CI/CD, observability, and operational readiness, ensuring systems are secure, compliant, and production-grade. Lead by example in modern engineering practices, including the responsible use of AI-assisted development tools to accelerate delivery and learning, while maintaining deep understanding, accountability, and ownership of all solutions produced. ## Related Videos - [Resolving technical debts in software architecture](https://www.wearedevelopers.com/videos/1680-resolving-technical-debts-in-software-architecture) - [Phel, a native Lisp for PHP](https://www.wearedevelopers.com/videos/791-phel-a-native-lisp-for-php) - [AI Pair Programming with GitHub Copilot at SAP: Looking Back, Looking Forward!](https://www.wearedevelopers.com/videos/1546-ai-pair-programming-with-github-copilot-at-sap-looking-back-looking-forward) - [Your next 10x engineer isn't in your city.
