Alicante, Spain (Hybrid 2–3 days in office required
We're looking for a Principal Software Engineer to operate at the intersection of deep technical expertise and cross-functional leadership. This is not a people management role. It's for someone who has spent 10+ years building real intuition for how complex systems work — and who can now translate that into architectural direction, fast decisions, and meaningful influence across the organization.
You'll be a reference point for the team: someone engineers come to when they're stuck, someone who can engage with product and infrastructure discussions without needing to be briefed from scratch, and someone who is genuinely excited about where AI is taking the craft.
At Lansweeper, we are building an AI-native engineering culture. We expect all engineers to actively use AI tools to enhance productivity and quality across the software development lifecycle, including coding, testing, documentation, and system design. Candidates should be comfortable working with AI-assisted workflows and continuously evolving their approach as tools and practices advance.
The main challenges you'll face are:
-
Driving architectural clarity across a distributed systems platform built in Go and Rust
-
Balancing speed, quality, and long-term maintainability in an AI-augmented development environment
-
Influencing technical direction across teams without formal authority
You will join an enthusiastic team of 40 engineers based in Spain (global engineering team is 120 people).
-
Set architectural direction for key areas of the Lansweeper platform
-
Act as a technical reference across engineering — and beyond, when needed
-
Engage with product, infrastructure, and business stakeholders to shape what gets built and how
-
Drive adoption of AI-native ways of working across the team
-
Mentor senior engineers and raise the technical bar across the organization
-
Identify and close gaps before they become problems
-
Collaborate with engineers across Alicante and internationally
-
10+ years of experience in software engineering, with a clear trajectory toward architecture and technical leadership
-
Strong experience building distributed systems in Go and/or Rust in production environments
-
Primary languages: Go and/or Rust (required)
-
Deep understanding of data modeling, APIs, and service-oriented architectures
-
Experience designing reliable and scalable systems in production
-
Hands-on expertise running services on Kubernetes with GitHub-based CI/CD
-
Strong experience with PostgreSQL and MongoDB
-
Practical experience using AI tools for coding, refactoring, testing, and documentation
-
Demonstrated experience influencing technical direction across teams
-
Have opinions, communicate them clearly, and build alignment without a formal mandate
-
Curious, self-directed, and passionate about building things inside and outside of work
-
Learn new tools and technologies quickly
-
Think in systems rather than isolated components
-
Prefer simple solutions over unnecessary complexity
-
Take ownership of engineering quality and long-term maintainability
-
Combine human judgment with AI-driven acceleration to deliver high-quality software
-
Operate with a high degree of autonomy, especially when requirements are vague or evolving
