Insider's spotlight

How would you describe the company’s work-life balance?

A lot of companies are so willing to sell you a story--join us, work all the time and buy into the dream. Trineo doesn’t pitch to people that way. We set up a workplace that’s balanced, that looks out for you. It’s good because it’s achievable, not aspirational. It’s the truth of what we have right now. I really appreciate it.



What kinds of technical challenges do you and your team face?

The architectural knowledge that we bring to the table is truly outstanding. We’re more strategic in how we approach client work. Our clients rely on us to go deep in their domain and work closely with them. It sets us apart from a lot other consultants who take orders, and roll out work, and it may or may not be what the customer is paying for.


Bespoke Practice Manager

What are some things you learned at the company?

The team put careful thought into laying the path for me to become a developer through an apprenticeship model. I have learned front and back end languages and frameworks and improved my public speaking. Most importantly, I have learned the value of working in a focussed, skilled and supportive team of intelligent, creative and kind people.



How do you make yourself accessible to the rest of the team?

My team is a collective of intelligent, capable people who are the best barometer of risk, reward and evolutionary progress. Their happiness correlates directly with the quality of our work and the happiness of our clients. They are therefore my first priority and we regularly see each other in person and communicate remotely via standups and 1:1s.


Cofounder and CEO

What does your typical day look like?

My typical workdays at Trineo start with a delicious flat white coffee made by a teammate (often our CEO). The majority of the day is a combination of solo work in flow, punctuated by strategic and planning meetings with colleagues. Most Fridays, the whole office enjoys happy hour together at a bar or on our patio overlooking Pearl Street.
