Portrait of Sergio Behrends

Sergio Behrends·Director of Engineering, Grover

Engineering leadership, from idea to shipped.

For 13+ years I’ve turned ideas into digital products people use every day — and built the teams that ship them — from a 12-person agency to the storefront platform behind €200M in annual recurring revenue. I lead engineering the way I learned to design: obsessed with what actually ships and how it feels to use.

What I do

01

Building engineering organizations

Team topology, hiring bars, career paths and growing engineers and managers — turning a group of engineers into an organization that ships and likes working together.

02

Product engineering at scale

Digital products where conversion, performance and reliability are the same conversation. Comfortable owning a domain that the business depends on.

03

Architecture & platforms

Developer experience, tooling and automation are what keep teams shipping — and the right architecture is what turns shipped into production-ready.

04

Design fluency

A real interest in great user experience, and the fluency to speak design natively — which is what makes design and engineering work as one team rather than two.

01 / Experience

A career built on shipping — and on building the teams that ship.

Developer first, manager by choice. Every role since has been about the same thing: teams that deliver products the business can bet on.

    Grover

    Director of Engineering

    Own the storefront domain end to end — the discovery, checkout and subscription experiences behind €200M in annual recurring revenue. Joined as an Engineering Manager for one storefront team, was promoted to Senior Engineering Manager in 2022 and then Director, now leading multiple teams and their managers. I pair with product and design on strategy, keep the platform fast and reliable, and make sure shipping stays easy as the organization grows.

Don’t take my word for it.

What the people I’ve built with — product partners, designers and engineers I’ve managed — say about working together.

  • One of the sharpest people I’ve worked with

    Sergio is one of the sharpest people I’ve worked with. He led before anyone gave him the title, and naturally grew into running our entire engineering team and shaping how we build digital products end to end. Easy going, clear communicator, and genuinely easy to work with. If you get the chance to work with him, take it.

    Agustín Linenberg·Co-Founder & CEO of Aerolab, worked together for 4 years
  • With him, the line between design and engineering simply disappeared.

    Sergio is one of those rare engineers who understands design from the inside. With him, the line between design and engineering simply disappeared — we’d debate every decision as equals, and the product was always better for it. He’s the kind of person who makes you want to go build something again.

    Alejandro Vizio·Creative Director at Aerolab, worked together for 4 years
  • The most complete Engineering Director I’ve had the privilege of partnering with.

    During our four years working together at Grover, Sergio consistently proved himself to be the most complete Engineering Director I’ve had the privilege of partnering with. What sets Sergio apart is his versatility: he is an exceptional leader who also stays remarkably connected to the actual work. By deeply understanding both the underlying technology and our core business objectives, he became an indispensable sparring partner for Product and Design. Sergio doesn’t just execute; he understands the strategic context, pushes technical boundaries, and empowers his entire team to thrive. He possesses a rare talent for driving multiple complex projects simultaneously while making it all look easy. Any organization would be incredibly lucky to have him.

    Thilo Schinke·Product Lead at Grover, worked together for 4 years
  • One of the most driven people I know

    I had the pleasure of working with Sergio at Aerolab, and he is easily one of the most driven people I know. When project turbulence hit, he never wasted energy looking backward or placing blame. Instead, Sergio always kept his eyes on the horizon, focusing entirely on how we could solve the problem and improve moving forward.
