Hubs.is - Agentic Platform Architect
Requirements
• We’re looking for a backend engineer who is both highly technical and pragmatic, excited to use AI tools to amplify their output and ship better products faster. You should bring: • Agentic Systems: Experience designing agent orchestration, planning/execution loops, or autonomous AI workflows — and a strong understanding of when and how to apply different LLMs. • Semantic & Knowledge Modeling: Familiarity with knowledge graphs, ontologies, or semantic data models, and how to represent and query structured knowledge for AI systems. • Concurrency & Reactive Architecture: Strong grasp of actor-based or reactive concurrency models, event-driven design, streaming APIs, and websockets. • Backend & Architecture: Strong experience with Node.js and frameworks like Nest.js or Express, plus a solid grasp of distributed systems, scaling patterns, microservices, and cloud infrastructure. • Databases: Hands-on expertise with both relational (Postgres) and document (MongoDB) databases • Productization Experience, Collaboration & Ownership, Critical Thinking & Communication, Pragmatism. • Experience Level: 5+ years of backend development, focusing on data systems and high-traffic web applications. • Languages & Technologies: TypeScript, Node.js, Python. • Databases: PostgreSQL and MongoDB at scale. • Performance optimization: Experience using observability tools, debugging, and performing root cause analysis. • Data Pipelines: Experience building scalable asynchronous pipelines, especially for language/AI data. • DevOps & Tools: Git, CI/CD processes; familiarity with Datadog, Digital Ocean, and/or GCP is a plus. • If you’re excited about building a product with potential for tremendous impact at the leading edge of AI-first productivity and collaboration, we’d love to hear from you!
Responsibilities
• Design and scale the agentic harness — the orchestration layer that plans, routes, and executes autonomous agent workflows reliably. • Architect the semantic knowledge base that models organizational knowledge and gives agents structured, retrievable context. • Build and evolve a reactive, actor-based execution engine for concurrent, event-driven agent execution with strong isolation and resilience. • Architect distributed systems with instrumentation that scale reliably and efficiently. • Collaborate with frontend, product, and devops teams to ensure seamless integration. • Architect for scale, performance, and efficiency at the logic, network, and database layers. • Lay foundations for high-quality distributed services that can evolve and grow as we scale out.
Benefits
• At Hubs, we’re committed to building not just transformative products, but also a place where ambitious builders can thrive. You’ll join a fast-moving, design-obsessed team where your ideas have real impact from day one. We offer a competitive salary, a chance for participation in upside via stock plans, and the flexibility of a remote-first environment. As an early member of the engineering team, you’ll help shape both our product and our culture, working alongside passionate people who care deeply about craft, autonomy, and creating experiences users love.
