Job Description: About This Role

We're seeking a product-minded Staff Engineer to join our Product Engineering team and drive meaningful customer impact through technology. As a Staff Engineer at Arkestro, you'll be embedded directly with Product and Design teams, working as a true product partner who deeply understands our customers' procurement challenges and builds solutions that transform how enterprises manage spend.

You'll own end-to-end product features from conception to customer adoption, balancing technical excellence with iteration and customer feedback. This isn't just about writing great code — it's about understanding the "why" behind every feature, measuring its impact on customer outcomes, and continuously improving the product experience. You'll work closely with customers, analyze usage data, and make technical decisions that directly influence product success.

The ideal candidate combines strong engineering fundamentals with genuine curiosity about our customers' workflows and pain points. This role is perfect for an engineer who thrives at the intersection of technology and product strategy, and who gets energized by seeing customers achieve breakthrough results with the software you build.
