Pros
Dexcom offers a great product. There is a strong desire among many staff members to use their careers to help people. The benefits and remuneration are competitive. The company appears positioned to benefit from tremendous growth in the near and mid terms at least. There are a number of fabulous individual contributors across many teams who are both exceptional at their trade and wonderful people to work with.
Cons
Very passive leadership leading to a lack of team identity, role conflict, role ambiguity, little to no help from leadership in remediating escalations, and lack of what I would call "organizational citizenship" among leaders and individual contributors alike (actions routinely taken to protect the organization). There is no 'effective' resource planning taking place leaving many of the star players overworked, mentally fatigued, and nearing burnout. Feedback and personal career development seem to be fleeting notions to all but a small number people reporting to the rare and exceptional manager despite elaborate work done by HR to overhaul title, job descriptions, and career ladders. Management often avoid action until mistakes or problems can no longer be ignored leaving fewer options at their disposal for remediation.
