Sr. Software Engineer (Agentic) en España is listed on Jobeax. Browse 80,000+ vacancies available.
Design, develop, and maintain robust, scalable backend services following Domain-Driven Design (DDD) principles.
Take full technical ownership of features - from design through deployment and monitoring.
Build and orchestrate agentic workflows: autonomous pipelines where AI models (Claude, LLMs) take actions, call tools, and solve tasks with minimal human intervention.
Actively participate in architecture decisions with strong analytical thinking and technical depth.
Ensure code quality through SDD, TDD, and BDD methodologies, with sharp attention to detail.
Collaborate on code reviews, refinements, and technical planning.
Proactively identify and address technical debt, performance bottlenecks, and security risks (OWASP, SOLID).
Build and maintain CI/CD pipelines across Bitbucket, GitLab, or GitHub.
Produce well-reasoned technical designs before writing the first line of code.
PHP (required) · JavaScript / https://jobeax.com/link/JSd7UYCSg572jJDY · Python
Rust (nice to have)
Full remote - work from anywhere within the European timezone (CET ±2h).
Small, technical team with minimal overhead.
Direct impact: your decisions ship to production.
A culture of honest feedback and continuous improvement.
Modern tooling - including cutting-edge AI - and freedom to propose new approaches.
A front-row seat to the agentic engineering shift, not just as a user but as a builder.
If this sounds like you and you want to build something that matters, we'd love to hear from you.

We're looking for a Senior Software Engineer with an Agentic mindset - someone who doesn't just write code, but builds systems that think, act, and adapt. You'll work on a production AdTech platform with real business impact, and you'll increasingly work alongside AI agents and design agentic workflows as part of your daily engineering practice.
This is not a ticket-execution role. We expect you to bring judgment, ask the hard questions, design thoughtfully, and genuinely care about the quality of what you ship - whether that code was written by you, assisted by AI, or executed autonomously by an agent you designed.

CI/CD pipelines (Bitbucket Pipelines, GitLab CI, GitHub Actions)
5+ years of experience in backend or full-stack software development.
Practical experience with agentic AI systems - building agents, designing tool use, working with LLM APIs, or automating complex workflows with AI.
Strong technical analysis and design skills: you can break down complex problems, propose well-reasoned solutions, and think through the implications of architectural decisions.
Critical thinking: you don't execute blindly. You question, challenge, and improve - including the outputs of AI tools.
Attention to detail: the code you ship is clean, tested, and documented. You apply the same standard to AI-generated code.
True ownership: you're accountable for what you build - in production, over time.
Autonomy: you know how to move forward without hand-holding, and when to raise a flag.
Proactive attitude: you surface improvements, catch problems before they become incidents, and share knowledge freely.
Eagerness to learn: the agentic era is moving fast, and you're moving with it.
Fluent professional English, written and spoken. The team is fully remote and multicultural.
