Software Builder

Job title: Software Builder

Location: Malaga

Hours: 37.5 hours

Working pattern: Hybrid, 3 days per week in the office

A-SAFE DIGITAL

Are you a Software Builder who already works with AI agents and wants to own real production outcomes?

At A-SAFE Digital in Malaga, we are building the Rails 8 platform that powers sales, service, catalog, orders and integrations for a global manufacturer. This is not a traditional software developer role: we build with Claude Code, write clear specs, direct agents, review critically and take responsibility for what reaches production.

How you will make an impact

• You will build with agents, not by hand, orchestrating Claude Code and similar coding agents across parallel branches to deliver high-quality software.
• You will own features end to end, taking work from a written spec through to a merged, tested and deployed PR.
• You will write specs that agents can execute, turning fuzzy goals into precise, testable instructions that become the contract for delivery.
• You will verify relentlessly, reviewing code from yourself, teammates and agents, and knowing the difference between “it runs” and “it is correct”.
• You will bring strong engineering judgement, making decisions on architecture, trade-offs, data models and integration design.
• You will keep production healthy, using tests, CI gates, observability and clear ownership to ensure what you ship is reliable.
• You will work in an AI-native engineering environment, where Claude Code is the daily driver and the route from idea to production is short.

What we are looking for

• Daily, practical experience using AI agents to build software, with clear opinions about where they help, where they fail and how to keep them on rails.
• Strong engineering fundamentals, with the ability to reason about systems and critically review code because your job is to judge output, not simply generate it.
• Spec and review discipline, including the ability to turn an unclear goal into a precise spec and catch almost-correct bugs that may pass tests but break in production.
• A strong ownership mindset, with a preference for owning one outcome end to end rather than being handed a list of disconnected tasks.
• Comfort across backend and frontend development, with Rails experience as a strong advantage.
• Experience working with production engineering practices such as tests, CI, PR-first workflows, observability and deployment ownership.
• A collaborative approach, suited to small pods, fast feedback and close working with product, engineering and business stakeholders.

Nice-to-haves

• Rails 8 and Hotwire experience in production, including Turbo and Stimulus.
• Integration experience across ERP, CRM, EDI, webhooks or similar business-critical systems.
• Experience with MCP or agent-driven systems beyond a demo.
• IoT or hardware-adjacent curiosity.
• Exposure to PostgreSQL, Packwerk, Sorbet, ClickHouse, AWS, Kubernetes/EKS, Terraform, Helm, GitHub, Jira, Confluence, Playwright or Sentry.

Benefits

• Opportunities for professional growth and career advancement.
• Collaborative and supportive work environment.
• Hybrid model: 3 days in the office, 2 days remote work.
• On-site pool and ping-pong table
• Intensive working hours (Jornada intensiva) in August: during this month we work from 8:00 to 15:00
• Flexible working hours with the option to finish early on Fridays.
