About the role The most senior individual-contributor seat in Solutions Engineering, not defined by a stage in the customer journey, but by scope: you're the final technical escalation point for Solutions Engineering, and the person who sets technical strategy and standard for the function as a whole. Where other Solutions Engineers own the deepest technical work on a given deal, you own the problems and decisions that span deals, route-to-market segments, and teams, like the ones with no existing playbook because nobody's had to solve them at this scale before. You're equally credible sketching an API flow with an engineer and discussing technical roadmap with an exec. In practice, that often means owning the deep API and OAuth-level integration and customization work behind the organization's highest-value enterprise and partner deals, the work that has historically had no clear owner, leaving sales and delivery teams to chase down the technical follow-through themselves. Here's what you'll do day-to-day • Serve as the final technical escalation point for the rarest, highest-ambiguity problems — the ones with no existing playbook. • Set standing technical strategy and direction for Solutions Engineering as a function, independent of any single route to market or deal. • Represent Solutions Engineering directly in cross-functional and executive conversations with Product, Engineering, and GTM leadership — translating technical reality into business decisions and vice versa. • Mentor and set the technical bar for the broader Solutions Engineering team — including coaching on the judgment calls that come with full deal/technical autonomy. • Own the technical strategy — and the hands-on build — behind the org's highest-stakes, most cross-functional initiatives: deep API and OAuth-based integration work for enterprise and partner accounts, from initial authorization through ongoing customization, end-to-end. • Act as the technical throughline between engineering/platform teams and go-to-market teams on the largest deals — making sure a committed integration or customization actually ships for the customer, instead of leaving that follow-through to sales. • Turn bespoke, one-off integration builds into reusable patterns and tooling other accounts and partners can adopt, rather than re-solving the same problem for every new deal. • Influence product and engineering roadmap from a position of pattern-recognition across the entire SE function, not just your own book. • Operate with full autonomy — no standard escalation path exists above this seat for day-to-day technical decisions. Here's what we're looking for • 8–12+ years of relevant experience, with significant time in a senior technical pre-sales, solutions-architecture, or implementation leadership role. • Proven track record operating independently on the most co
