We're looking for a Staff/Principal Platform Engineer to lead the design and evolution of the Kape Partner Portal — our B2B platform that lets partners license our services and integrate our SDKs into their own products. This is a high-ownership, cross-stack role: you'll shape architecture end-to-end across backend and frontend, while leading AI-assisted engineering at scale. You'll own the technical direction of a multi-tenant platform covering partner onboarding, entitlements, SDK licensing, configuration management, and operational visibility. The role suits someone who thinks in systems, communicates clearly with both engineers and business stakeholders, and is excited about driving AI-orchestrated engineering workflows rather than maintaining legacy patterns. What You'll Do
Own end-to-end architecture of the Kape Partner Portal — backend services in Rust, the Next.js frontend, and everything in between
Design and evolve the multi-tenant control plane
Lead AI-assisted development with Claude Code — designing prompts and workflows, orchestrating sub-agents, reviewing and validating generated output, and shaping how the team uses AI to ship faster without sacrificing quality
Make pragmatic technology choices across the full stack (Rust, Next.js, PostgreSQL, Redis) and across infrastructure (AWS, ideally with Terraform/Scalr)
Define and own observability, reliability, and security standards (Prometheus, Grafana, structured logging, alerting)
Design clean, well-documented REST APIs for internal services and partner integrations
Partner closely with product, business, and customer-facing teams — including running technical sessions and presentations directly with enterprise customers
Establish and uphold high engineering standards through code reviews, testing practices, and clear documentation
What You'll Bring
Proven experience architecting scalable, multi-tenant B2B systems end-to-end, ideally in a SaaS context where you've bridged engineering and business needs
Comfort working across the full stack — backend, frontend, databases, caching — with a clear mental model of how the pieces fit together. We use Rust (backend) and Next.js (frontend), but transferable cross-stack experience is what matters most
A modern view on AI-assisted engineering. Experience orchestrating, guiding, and supervising AI agents (Claude Code or similar) to deliver production-grade systems is more important to us than years of hands-on Rust experience. The ability to direct AI well is the leverage point of this role
Strong system design fundamentals: distributed systems, concurrency, performance trade-offs, reliability
Solid understanding of REST API design, database modeling, and caching strategies
Excellent communication skills — equally comfortable in deep technical reviews and in front of enterprise customers
High degree of ownership and the ability to operate independently with minimal direction
Nice to Have
Experience with Terraform / Scalr in an AWS environment
Hands-on experience with Prometheus and Grafana
Background in identity, authentication, secure networking, or VPN platforms
Experience designing or shipping SDKs and cross-platform libraries
What We Offer
Work with a modern tech stack in a strong engineering culture
Influence on technical decisions and room to innovate
Continuous learning opportunities and support for professional development
A motivated, collaborative team with flat hierarchies
A strategic role with real technical influence and ownership
A modern engineering culture with CI/CD, observability, and a strong code review culture
Purpose-driven work: we value security, quality, and depth over quick hacks
How We'll Support You
We believe in fostering an environment that empowers decision-making at all levels. Our culture is rooted in the inverted pyramid approach, where the engineers — who have a deep understanding of the product and the customers — are the ones who have the knowledge and the authority to make impactful decisions. We promote equal recruitment and employment opportunities, and do not discriminate based on gender identity and/or expression, age, race, color, disability, culture, religion or belief, family and/or marital status, sexual orientation, or other characteristics protected by applicable law. We celebrate a diverse and inclusive work environment in which applicants and employees are treated with respect and dignity, and excel based on personal merit, qualifications, experience, and performance.*
