Principal Engineer, Reach

THE OPPORTUNITY

Riverside Insights' Potential & Placement vertical has a clear north star: ensure every student with exceptional ability, outstanding potential, or unique learning needs is found as early as possible and given the opportunity to thrive. CogAT and Iowa Assessments are how school districts do that today, together a nearly $50M business already serving 3 million students.

This is a hands-on, principal-level technical role. You're the senior technical owner, not managing a team through someone else's architecture: writing code, in the architecture, shoulder to shoulder with your engineers every day.

The opportunity itself is rare: build an enterprise-grade platform from the ground up inside an organization with a trusted brand, established product-market fit, and millions of students already served. You're not proving the market exists, you're building the platform architecture and data model that let it grow, at the security bar of a regulated data environment (FERPA, COPPA, and similar), while making the build-vs-buy-vs-partner calls on core components like the adaptive engine, test delivery, and rostering.

You won't inherit existing architecture, tech debt, or a team. You'll build all three, on the path to an ambitious target: a 2028 launch and migrating our first million students onto this new platform. Once you're deep on the existing systems and the migration plan, you'll define and build the fully dedicated technical team to execute it, drawing on Riverside's existing talent and new hires you bring in, within your first 60 days. You'll work closely with product, psychometrics, and content throughout.

Make no mistake: this isn't a B2C mobile app. You're architecting a complex, multi-component platform, built for real production volume and the workflows of schools and districts.

This is a small company mandate inside an established organization: a lean, scrappy, agile mindset, moving with real speed and without ego, in pursuit of an industry-changing vision that gets millions more kids found and given the support they need.

This role reports to the Chief Technology Officer. WHAT YOU'LL DO

Lead the 0-to-1 build. Own architecture, construction, and testing of the Reach platform through a Fall 2027 pilot, and the next-generation CogAT assessment through full 2028 launch.

Architect for B2B scale. Design a complex, multi-component platform built for real production volume and institutional buyers, meeting the compliance bar of a regulated data environment.

Build your team, within 60 days. Get deep on existing systems and the migration plan, then define the team you need and build it, drawing on existing talent and new hires within a 6-10 engineer budget.

Own the first migration wave. Ensure the initial cohort of customers moving onto the new platform gets a day-one experience that's better than what they had, not just a like-for-like switch.

Stay hands-on. Actively coding alongside your team, not reviewing architecture diagrams from a distance.

Own build-vs-buy-vs-partner calls on core technical dependencies, adaptive engine, test delivery, rostering, with clear, cost- and risk-informed recommendations.

Set the standard for AI-native engineering at Riverside, ways of working that let a small team move like a much bigger one.

Own technical roadmap execution. Translate the Product team’s roadmap into a technical plan, sequencing architecture and infrastructure work, including where and how AI gets built into core capabilities like the Reporting Engine.

Partner across the business. Regular demos of working software, transparent updates on progress, risk, and decisions needed.
