Great place to work, for as long as they'll keep you.
Pros
Syndio is a small HR tech startup with a fantastic understanding that developers will create tools for themselves to augment their productivity, if they aren't constantly overworked all the time. The internal tooling is second to none, with a very rapid code-to-test-to-deploy cycle. The pay is phenomenal, I was given the minimum stated salary for my role and was still very, very happy with the compensation. Engineering culture is very good. All engineers are open to constructive feedback, and everything feels like a discussion, not a lecture. It's apparent that Syndio prides itself on its culture-fit selection, ensuring only positive people contribute to the environment.
Cons
I cannot earnestly give five stars as I was laid off from the company six months after my position was created and I was hired. I was reassured this was not performance related, and I'd have been kept on if at all possible. This is sadly indicative of poor long-term planning and a disregard for the workforce's wellbeing. I made clear in interviews I was looking for a stable opportunity I could stay in for a good few years, where I could grow as an engineer. To be hired on this premise then let go so soon is very disappointing. Recently (at time of writing) there been has somewhat worrying amount of turnover and shuffling in the more senior echelons of the organisation. Leadership is yet to address this, and concerns are rising.
