Pros

- Small but talented group of engineers - Rewarding field (assisting in cancer diagnosis)

Cons

- CEO has a $5m TC package while the employees creating the products are on government assistance - Company constantly violates HIPAA and instructs employees to lie to customers about downtime/security vulnerabilities to avoid voiding our contracts. Literal criminals - Zero growth opportunities. I received several title changes which meant nothing more than added work for zero pay while CEO Tom Logan and his sidekick Sheila Webb get regular bonuses/promotions - You're surrounded by people who know so little about technology or software in general that it's genuinely comical - Quite literally the lowest compensation in the state for the position, extremely low for national average as well

Pros

I am truly grateful to have crossed paths with many of my colleagues, who I found to be very smart and capable. Benefits are decent, and they have an on-site cafeteria.

Cons

Low salaries, poor raises, very limited opportunities for advancement, and an incredibly dysfunctional, toxic work environment. The current site leadership here is incredibly unprofessional, and can be openly hostile to any employees who fail to properly "kiss the ring". Staffing is lean, most departments are chronically understaffed, and experience abnormally high turnover. Advancement is possible, but it requires a complete lack of work/life balance, and the lack of any meaningful raises means you'll be making less than new hires by the time you actually get promoted. HR is absolutely atrocious, and actively enables a culture of retaliation. Middle management is largely composed of incompetent yes-people. High performers people are regularly thrown under the bus and let go in order to pass blame downwards, I've seen many talented people get go for incredibly petty/retaliatory reasons by their ineffectual bosses to prevent themselves from getting fired. As a result, many departments are locked into a perpetual cycle of trying to shift blame onto one another, resulting in a debilitating amount of infighting; a direct reflection of the poor leadership of the organization. Upper management is incredibly top-heavy, and entirely detached from the day to day operations of the organization. Outside of a continuous push for monthly, quarterly, and annual revenue to appease shareholders, little to no effort is made to resolve in day to day problems faced by employees. Higher level positions are almost always external hires. Numerous desperately needed positions are regularly unfilled/get withdrawn due to lack of budget allocation from upper management.

Pros

Great service director and opportunities for movement within the company if you can stand the environment

Cons

Unequipped field supervisors, 0 people reached out to see how things were going, no 1:1s, they will assume before asking and needs DEI training Severely!
