DataBase Engineer

Lisboa

Job description

We are looking for a Senior Database Migration Engineer to join an agile, collaborative team where your voice matters as much as your code.

You won't just be managing databases; you'll be a technical partner helping us migrate and modernize our architecture.

We value empathy, self-organization, and the courage to take risks. If you love solving complex database challenges and believe that teaching others is the best way to learn, you'll feel right at home here.

We're looking for someone who loves to build, learn, and guide others. You'll be working closely with our development teams and our clients, so clear communication and a collaborative spirit are key.

National and international expected traveling time varies according to project/client and organizational needs: 0%-15% estimated.

How You'll Contribute
  • Architect & Migrate: Partner with our teams to guide the migration of our monolithic MS SQL Server database to a highly scalable, distributed read/write PostgreSQL architecture.
  • Build & Refactor Schema: Translate complex legacy database logic into optimized modern queries, moving seamlessly from T-SQL to PL/pgSQL.
  • Embrace AI-Assisted Engineering: Actively explore, trial, and integrate advanced AI tooling—specifically Claude Code—into your daily database engineering workflows to accelerate refactoring and optimization.
  • Design for Distribution: Work on indexing, partitioning strategies, and high-performing configuration setups to ensure seamless read/write performance across a multi-node database environment.

Requirements

  • Bridges Data and Software Engineering: You have a solid understanding of engineering and architectural principles, applying a software engineer's mindset to solve complex infrastructure and data modeling challenges.
  • Has Senior-Level Impact: You bring a track record of end-to-end database delivery in fast-paced environments, with deep expertise in SQL and database internals.
  • Values Collaboration: You collaborate openly on database workflows and are an excellent communicator capable of translating complex technical database concepts to leadership and partners in English.

Your Technical Toolkit:

  • Database Engines: High mid-to-senior level expertise in PostgreSQL and/or MS SQL Server (having hands-on experience with both is highly valued).
  • Modern AI Tools: Experience playing with or actively using LLMs and AI programming assistants (such as Claude Code, GitHub Copilot, or Cursor) to augment your daily development.
  • Distributed Architecture: Conceptual or hands-on familiarity with distributed database environments, partitioning, replication, and performance tuning.
