About FusionAuth

FusionAuth is a developer-first customer identity platform that gives engineering teams complete control over authentication, authorization, and user management. We serve organizations across B2C, B2B, and B2B2C with a single-tenant architecture, flexible hosting options, and deep extensibility through APIs, webhooks, and advanced customizations.


We're a fast-growing company solving complicated identity problems for teams that care about control, performance, and security. Our Solutions Engineering team sits at the center of product, engineering, and revenue -- guiding prospects through architecture decisions, supporting complex proof-of-concepts, and helping them evaluate FusionAuth with clarity and confidence.


If you love talking to developers, diagramming architectures, building sample apps, and helping teams understand the "why" behind identity decisions, this role is for you.

Job Summary

Your Role: The Hero of Solutions Engineering

As a Solutions Engineer, your mission is to drive the technical win. You'll team up with Account Executives to run deep discovery, demonstrate FusionAuth's capabilities, build trust with engineering teams, and guide prospects through solution design, hosting choices, and identity architecture decisions.


This isn't a "demo jockey" role -- our SEs write code, build PoCs, advise on CIAM best practices, and advocate for developers. You'll influence product direction, collaborate closely with engineering, and shape how organizations adopt FusionAuth in the real world.

Responsibilities

Drive Technical Discovery & Solution Design

Lead discovery sessions that uncover technical requirements, constraints, and success criteria. Build and present architectural recommendations tailored to each prospect's environment and model (B2C, B2B, B2B2C, app suites, multi-tenant SaaS, M2M). Guide prospects through modern auth patterns (OAuth, OIDC, SAML, MFA, SSO, token exchange, mTLS, DPoP, FGA, etc.).

Deliver Developer-First Technical Evaluations

Run demos that speak directly to engineering teams -- hands-on, credible, and real. Build example apps, scripts, and integration patterns using FusionAuth, modern frameworks, and cloud tooling. Support structured proofs of concept, including async Slack support, environment setup guidance, sample payloads, and success criteria alignment.

Hosting, Architecture & Deployment Guidance

Advise on FusionAuth hosting tiers (Basic, Business, HA) and help prospects understand cost, scale, and operational tradeoffs. Assist with customer environments: Docker, Kubernetes, containers, microservices, cloud infra, CI/CD, and DevOps patterns. Help prospects align FusionAuth with compliance, security, and regional requirements.

Collaboration, Documentation & Process

Partner with product and engineering to ensure field requirements are heard and prioritized. Contribute documentation, internal runbooks, diagrams, and developer-focused content. Participate in creating Consensus workflows, Problem/Solution videos, and technical demo assets.

Represent FusionAuth Externally

Present at meetups, webinars, and developer-focused events. Collaborate with DevRel and Product Marketing to create authentic developer content. Serve as a credible technical voice in the identity community.
