Specialized Engineering Talent for Complex Projects

Engineering isn’t one-size-fits-all, and neither is our approach to staffing. At STSI, we understand that every discipline has its own demands, standards, tools, and pace. Whether you’re designing process systems for a pharmaceutical facility, optimizing MEP layouts in a mission-critical data center, or leading a capital project in oil & gas, you need engineers who bring more than credentials—you need precision, performance, and impact.

With over 30 years of experience, we’ve built a robust network of engineering talent across the most complex, compliance-driven, and innovation-focused industries in North America.

STSI are great partners to work with. The team knows the business they support and are always more than willing to help out with filling difficult positions. They provide valuable feedback to hiring managers regarding their job postings as well as recommendations for challenging to fill roles, using their “thinking outside the box” approach to problem solving. Last but certainly not least, they build relationships with their candidates that they submit and those candidates remain loyal to working for them – this to me shows that they ‘value their employees and really work to do what is best for them as individuals.
