Horrible data organization

Pros

Perks are great. Building is beautiful. Slack, as a product, is useful.

Cons

Data org has no strategy or vision. Most engineering managers don't care about their team members. The very few who do aren't supported by the senior leadership. No focus on engineering quality and the happiness of the engineers. VPs and directors overpromise to the execs. They get upset when their unreasonable demands aren't met. Horrendous amount of cross department politics. Constant on-call issues and pages. Small teams supporting large number of projects and constantly struggling to keep up. No appreciation or recognition of th good work. CTO belittles the data org when things go wrong. He seems unhappy with the team, but does nothing to understand and correct any issues. I can keep going but hopefully you got the idea!

Pros

Game changing technology and massive market opportunity ahead - We're 1% penetrated in a 700 million knowledge worker market. Unique culture that emphasizes customer and team first. Great opportunity for career growth: A colleague was promoted to manager role and many others have been promoted into Senior AE roles. Achieved some great milestones in 2017 including landing Large Enterprise logos that few 4 year old companies can boast about: IBM, Oracle, SAP, American Express, Capital One, eBay, Paypal, Walmart. Best parts about working at Slack: Being surround by intelligent, empathetic teammates, helping effect a fundamental change in how people use technology to get work done, exciting personal career growth and earnings opportunities, and visionary leadership from Stewart Butterfield who has surrounded himself with an impressive executive team.

Cons

The sales organization still comprises a smaller percentage of the total employees, so developing a strong voice/seat at the table with larger product and engineering organization has taken time. I've seen positive changes over the last year here so I anticipate progress will continue to improve.
