Pros: Sigma has a wonderful culture and atmosphere - people are friendly, coworkers enjoy socializing together, and there's excitement around Sigma's continued success. The engineering department has a great VP who has vision and experience scaling small teams. Due to the founders being technical, there's a strong engineering culture within the company, with technical feasibility a first-class citizen among leadership. For example, due to site reliability issues, all of engineering took a month to focus on stability and tech debt instead of feature development, something I've never experienced on another production app. Post-pandemic, the company has moved to a hybrid work culture, with teams in the office 2-3 days / week. The leadership is fantastic. I've seen people be fired, but their last day of "official" employment delayed just so their options vest. Instead of trying to screw people out of every dollar like many places might, Sigma has consistently done right by people. They also do a comp adjustment to ensure existing engineers aren't getting paid less than incoming engineers.

Cons: On the one hand, having two founders who are brilliantly technical means there are tremendous opportunities to learn and grow. Both Rob and Jason actively and regularly push and review code. However, they both much prefer doing to teaching/leading, so less experienced engineers often find themselves floundering. I'd also be remiss if I didn't mention that one of the founders has a rather contentious approach that not everyone enjoys. If you work in a similar part of the codebase as him, you'll have to prove to him you know what you're doing before he trusts you. In the absence of that trust, expect extensive PR reviews. Feedback loop is nonexistent - both IC and managers often have no idea how they're doing until it's too late. Iteration speed is often high, with it occasionally impacting work / life balance. Leadership is a bit of a stickler about coming into the office.

Pros: There are great coworkers, free lunch, and a nice office.

Cons: It appears that Sigma’s leadership has taken inspiration from Elon’s style, fostering a negative culture and a toxic work environment. Employees are expected to work long hours. Glassdoor reviews are inflated and misleading. If you plan to work on fronted, all of your front end PRs will be blocked by one of the cofounders and you will have to deal with his toxic comments, please take it seriously as it will happen. Career growth path is unclear. There is favoritism. There is little diversity. The company’s primary focus is on hiring new graduates. Senior engineers are heavily involved in mentoring new grads, which creates significant distractions from their own projects, yet there is nothing offered in return.

Pros: You'll meet some wonderful people working here.

Cons: Leadership lacks transparency! Relevant and important information is often kept secret and consistently on a "need-to-know basis," which makes leadership seem dishonest and insincere. There's a lack of transparency on the company's direction and a growing culture of fear that has been reported multiple times. Basically, the environment is "you're here to do a job; we pay better than most startups, so do your job and don't ask questions." You're a cog in the machine, not a team member. And you'll be constantly bombarded with "investor talk" during all-hands (God they even use the same slides). Sigma used to be a great place to work, but now it's transitioning to a corporate culture without building trust with its employees.
