• Early-stage startup with a focus on work-life balance and long-term thinking
• We’re an early-stage startup. While the business needs mean we can’t promise you a regular 40-hour workweek, we try our best to respect weekends, vacations, and life outside of work. We believe that Codex should serve its customers and employees long term - and that begins with ensuring employee burnout isn’t a part of our employee life.

We dream big and we want to help each other succeed and reach our career goals. We do this through encouraging open communication, empathetic feedback, sharing ideas, listening to each other's perspectives, being available for bespoke 1:1s, and having an overall willingne
