Mid/Senior Software Engineer (AI Coding Agents)

Mid • Remote

Lisbon, Portugal

Quick Facts

  • Role: Mid/Senior Software Engineer

  • Focus: Daily use of AI coding agents across development and engineering workflows

  • Scope: Modern (C#/.NET) and legacy systems (COBOL, Delphi, PowerBuilder, FoxPro, WinDev)

Description

You will be a hands-on advocate of AI within the team—using AI coding agents every day rather than only discussing AI-assisted development. The role spans modern application development and the analysis, documentation, maintenance, and modernization of legacy codebases, including work where legacy logic is brought into modern architectures.

Responsibilities

  • Lead by example in daily use of AI coding agents (development, testing, documentation, and code review)

  • Configure and maintain agent setups (rules, instructions, prompt libraries, context files, reusable workflows)

  • Share what works via demos, pair-programming, and internal workshops

  • Identify repetitive tasks that can be accelerated with agentic approaches

  • Bring pragmatic ideas from the evolving AI tooling landscape

  • Develop, maintain, and evolve applications across the full technology landscape, including bug fixing and new features

  • Use AI agents to write, review, and test code and to analyze and explain legacy business rules and data flows

  • Contribute to modernization initiatives and migrations from legacy to modern architectures

  • Help shape modern architecture so it can absorb what’s being modernized

  • Build and maintain a shared knowledge base across legacy and modern systems

  • Design, develop, and maintain backend and frontend features

  • Write clean, maintainable code following SOLID and good architectural practices

  • Participate in code reviews

  • Work with CI/CD pipelines and cloud environments to build and deploy

  • Collaborate with product, QA, DevOps, and engineering teams

  • Support and mentor less experienced engineers, especially in AI-assisted development

Requirements

  • 4 to 6 years of professional software development experience

  • Hands-on, day-to-day experience with AI coding agents (GitHub Copilot, Cursor, Claude Code), including configuration/rules/instructions

  • Experience building agentic workflows, MCP servers, or custom AI tooling

  • Openness and willingness to work with legacy technologies (COBOL, Delphi, PowerBuilder, FoxPro, WinDev)

  • Solid experience with at least one modern stack, ideally C#/.NET and/or React/TypeScript/JavaScript

  • Experience with relational databases and SQL

  • Practical experience writing automated tests (unit, integration and/or end-to-end)

  • Familiarity with Git, CI/CD pipelines, and Agile

  • Fluent English (mandatory)
