• Growth through learning and career pivots: MassMutual supports technical growth through on-demand learning, stretch assignments, mentoring, education assistance and manager check-ins. A product management consultant described moving into product work with support from an “incredibly supportive team,” while a head of data science said employees stay engaged through stretch projects, mentoring teammates and presenting work internally and externally.
• Supportive leadership and strategic direction: Tech managers connect work to business priorities and help employees understand the “why” behind projects. A head of data science said the best engineers and data scientists ask, “Why?” and that teams set a “north star” before working backward from ambitious goals. A lead full stack developer described Product and Operations leadership as “very forward looking” with “an impressive vision for the company and for the new products being built.”
• External signals:
