Pros

High Tech company. Good work-life balance.

Cons

1/10 for loyalty. After Being with them for nearly 7 years, they shut down the Cyber Security department, makeing the entire team redundant. Firstly, a silly business decision in this time of Quantum Origin and PQC. Failed by poor leadership, poor management and poor foresight. Poor and blinkered vision. Secondly, zero compassion, zero appreciation for loyalty. The department head engineered his own promotion, and then, from his pedestal, sunk his own ship. Beware of the Applications Group.

Pros

The science put out by Quantinuum is excellent, and many incredibly smart physicists are working on some of the most interesting problems in quantum computing. As a physicist the work we get to do is very fulfilling and most teams have reasonable work life balance (though not all do). Many scientists value working at a company that makes credible and realistic claims, which is often not the case in the quantum computing space. This has been relatively easy for Quantinuum to maintain as it has consistently developed some of the best quantum computing hardware in the world and is staffed by many incredible scientists and engineers.

Cons

The pay is low and benefits are lacking relative to competitors. While broadly speaking work-life balance is reasonable, certain teams are expected to put in huge hours to get things done on time, and this can extend over significant periods of time. While the RSUs that are offered certainly have reasonable expectation value, it is entirely unclear when that value will be realized. The CEO making vague and contradictory statements about these issues does not provide much room for optimism on this topic amongst employees and does not inspire confidence in the executive team.
