Principal Developer

🇦🇷 Available to work remotely from Argentina

The job proposal

In Aerolab, we have a user-centered approach to create digital products: websites, applications, interfaces, you name it.

We are always evolving and finding new ways of doing things. All our processes are in constant iteration, and our focus is on learning.

As a Principal Developer, your impact goes beyond writing great code. You’ll bring clarity to complex problems, guide teams, drive strategy, and act as a technical reference across multiple projects. This is a senior, high-impact role designed for experienced engineers who thrive at the intersection of execution and vision.

You’ll work closely with designers, developers, and clients, helping shape not just how we build, but why. You’ll also have the freedom to explore, improve, and leave your mark — technically and culturally.

Your job responsibilities include

With the team and across projects:

• Lead technical execution across 2–3 active projects simultaneously.

• Ensure technical progress and deadlines are met — or adjusted early.

• Detect risks and opportunities in advance and propose clear action plans.

• Participate in (or lead) technical discoveries, PoCs, and product architectures.

• Guide implementation, documentation, and code quality across teams.

• Jump in when needed: code, review, validate design decisions.

• Contribute to strategic decisions that shape both product and platform.

• Share knowledge and support junior and mid-level devs when it matters most.

This role includes technical mentorship in the context of projects, but does not include direct responsibility for people development.

With the client:

• Translate technical challenges into business risks and opportunities.

• Define technical scopes that match real-world needs and constraints.

• Make complex decisions easier by clearly explaining implications and trade-offs.

• Act as a trusted partner for clients, building confidence through clarity and expertise.

• Lead key moments — like discovery presentations or alignment meetings.

At the organizational level:

• Suggest improvements to tools, processes, and infrastructure.

• Help evolve our stack and explore new technologies with purpose.

• Document best practices and scale good decisions across teams.

• Lead or participate in internal learning spaces (workshops, courses, etc).

• Provide technical input during interviews, estimations, and team evaluations.

What do we expect from you?

Technical experience:

• +5 years of proven expertise in full-stack development and software architecture.

• Experience leading or guiding development teams both technically and strategically.

• Ability to evaluate scalability and design decisions at a system level.

• Experience in technical discoveries, PoCs, architecture reviews, and documentation.

• Deep knowledge of modern dev tools, testing practices, and CI/CD pipelines.

Strategic thinking:

• Understand how technical decisions impact product, business, and users.

• Anticipate future risks — and design sustainable solutions ahead of time.

• Product-minded: can prioritize, question, and seek value in every decision.

Interpersonal skills:

• Natural technical leader and go-to person for peers.

• Strong communicator: clear, honest, and focused on alignment.

• Collaborative by default: drives consensus and elevates conversations.

What are you going to find at Aerolab?

• The opportunity to work on products of different industries, having direct contact with the client.

• Spaces designed to give feedback and propose improvements and changes.

• Aerolab is a member of SoDA, a global network of leading digital agencies
