Highlights
Senior engineering opportunity centered on scalable enterprise SaaS, complex integrations, event-driven architecture, workflow orchestration, and enterprise-grade security. The role offers substantial ownership over robust backend and full-stack systems without requiring AI/ML model development.
Description
JOB SUMMARY
We're looking for a Senior Backend/Full-Stack Engineer to build and scale our enterprise SaaS platform, with a focus on third-party integrations and workflow orchestration.
This is not an AI/ML role, while the platform includes an AI component (a Small Language Model, or "SLM"), this engineer will consume it as a service, not build or train it.
JOB RESPONSIBILITIES
Design, build, and maintain backend/full-stack systems for our enterprise B2B SaaS platformBuild and maintain adapters/integrations against third-party enterprise APIs, handling OAuth/SCIM, webhooks, rate limits, flaky vendor endpoints, and API versioningDesign and develop event-driven systems, including queues, workflow orchestration, and idempotency handling — directly supporting our blueprint execution engine (a workflow engine)Implement and maintain enterprise-grade security and compliance features, including RBAC, SSO/SAML, audit logging, and tamper-evident records (our "Evidence Vault")Support self-hosted/on-prem deployments using Docker and KubernetesIntegrate with our SLM (Small Language Model) as a consumer service — working with structured outputs, retrieval-augmented workflows, and eval-aware developmentTake ownership of architectural decisions and technical direction, not just feature deliveryMentor other engineers and provide technical guidance across the teamReview and push back on specs where appropriate, proposing alternative technical approaches
JOB QUALIFICATIONS:
5+ years of backend or full-stack development experience on enterprise B2B SaaS shipped to production (agency or portfolio-only work will not be considered)Strong background in a statically typed language; Rust proficiency preferred, or demonstrated ability to ramp up quickly in RustProven, hands-on experience building integrations/adapters against third-party enterprise APIs (OAuth/SCIM, webhooks, rate limiting, versioning)Experience with event-driven architecture: queues, workflow orchestration, idempotencyExperience with enterprise security/compliance implementations: RBAC, SSO/SAML, audit logging, on-prem/self-hosted deployment (Docker, Kubernetes)Comfortable working with AI/LLM services as a consumer (structured outputs, retrieval, evaluation) — ML/AI engineering background is explicitly not required or expectedStrong communication skills and comfort challenging specs or proposing alternative solutionsPrior experience mentoring or providing technical leadership to other engineers
