Seek better compensated engineering roles with work-life balance

With 6.5 years of engineering experience, making $77,000 while doing the work of '3 engineers + helping with manufacturing + doing quality stuff' indicates severe underpayment and burnout. This individual is highly qualified for better-compensated roles with more reasonable workloads. They should focus on leveraging their multi-faceted experience (engineering, manufacturing, quality) to target Senior Engineer, Project Engineer, or even Engineering Lead positions in companies that value work-life balance and offer competitive salaries (likely significantly higher than $77k, especially in the US for 6.5 years of experience). Emphasize problem-solving, project contributions, and efficiency improvements in their resume.
