What is a Software Engineer at Olsson?

At Olsson, a Software Engineer—often specializing in controls engineering, building management systems (BMS), and infrastructure automation—plays a vital role in bridging the gap between physical engineering and digital intelligence. Unlike traditional software companies focused solely on consumer applications, Olsson is a premier engineering design firm. This means your work as a software or controls engineer directly impacts critical, large-scale physical infrastructure, including data centers, rail networks, and advanced building systems.

You will design, program, and implement the software and control systems that keep high-stakes environments running safely and efficiently. Whether you are developing automation logic for massive data center cooling systems or integrating software platforms for complex civil and electrical projects, your contributions ensure operational resilience. The role demands a unique blend of software development practices and an understanding of physical engineering principles.

This position is highly collaborative. You will not write code in a silo; instead, you will work closely with civil, electrical, and mechanical engineers to deliver integrated, turn-key solutions for clients. For professionals who enjoy seeing their code control real-world systems and critical infrastructure, this role offers an incredibly rewarding and tangible engineering challenge.

Common Interview Questions

To succeed in the Olsson hiring process, you must prepare for a blend of behavioral, professional background, and domain-specific questions. While the interview style is famously conversational, the questions are designed to assess how you collaborate with multi-disciplinary teams and apply your technical mind to real-world problems.

Getting Ready for Your Interviews

Preparing for an interview at Olsson requires a shift in mindset compared to standard tech-industry preparation. Because Olsson is an engineering consulting firm, they prioritize communication, adaptability, and practical problem-solving over abstract coding riddles.

Cultural and Relational AlignmentOlsson places an immense emphasis on who you are as a person. Interviewers look for down-to-earth, authentic, and easy-to-talk-to candidates who will thrive in a collaborative, client-focused environment. Be prepared to share stories that demonstrate your humility, curiosity, and work ethic.

Domain and Systems Integration – You must show an understanding of how software interacts with physical systems. Whether your background is in computer science, controls, or electrical engineering, you need to demonstrate that you can think about the "whole system"—including hardware, software, and human operators.

Communication and Stakeholder Management – As an engineer at Olsson, you will frequently interact with professionals from other disciplines. You must be able to explain complex technical concepts in simple, clear language. Practice articulating your technical decisions and their practical business or physical impacts.

Interview Process Overview

The interview process at Olsson is structured to be smooth, straightforward, and highly personal. It is designed to feel more like a mutual conversation than an interrogation. The company stays away from "trap" or "trick" questions, focusing instead on honest dialogue and mutual fit.

The process typically begins with a standard screening call with human resources to discuss your background, interest in the company, and basic qualifications. If there is a mutual fit, you will move to the next stage, which is usually a virtual or in-person panel interview. This panel typically consists of engineering managers, team leads, and potential peers. For higher-level or specialized roles, this stage may include a second, more informal conversation with regional leadership or direct managers, along with a tour of one of their campus offices.

Key Responsibilities

As a Software Engineer or Controls Engineer at Olsson, your daily work will be highly dynamic and deeply integrated with physical engineering projects.

You will be responsible for designing, programming, and testing software and control systems for a variety of clients, particularly in high-growth sectors like data centers, federal facilities, and transport infrastructure. This involves writing clean, reliable control logic, configuring building management systems (BMS), and developing user interfaces that allow operators to monitor complex systems.

Collaboration is a massive part of your day-to-day life. You will regularly meet with mechanical, electrical, and civil engineers to review project plans, translate physical requirements into software specifications, and coordinate deployment schedules.

Additionally, you will participate in the commissioning phase of projects. This means you will occasionally travel to client sites to test your software on-site, troubleshoot physical integrations, and ensure that the systems perform flawlessly under real-world conditions.

Role Requirements & Qualifications

To be competitive for this role at Olsson, you should possess a strong foundation in engineering principles paired with practical software or controls experience.
