Hey HN - I'm George, founder of xFigura. We're building the AI-native creative canvas for architects - Figma for the built world.

The problem: Architects design where you live, work, get surgery, send your kids to school. Their tools? AutoCAD (1982). Revit (2000). The physical world runs on software older than the iPhone.

Six months in, we have 5 of the top 20 architecture firms using the product. No marketing, $0 to $1M ARR in less than a year, and we just closed a $3M seed round.

What we're building: AI orchestration across 50+ generative models, infinite canvas collaboration, native CAD integrations (Rhino, Speckle, Revit), enterprise RAG for firm-specific knowledge.

Stack: DynamoDB, Next.js, Tailwind, AWS, FastAPI. Looking for someone who's shipped production AI systems and is in the 99th percentile of using AI in their own workflow (Cursor, Claude, etc.).

Small team, huge ownership. You'd own entire systems, not tickets.

Email me directly: info@xfigura.ai (mention HN in Subject)

We’re a small, senior team of product-minded engineers who value quality, simplicity, curiosity, and collaboration.

Some of the problems we're actively working on: - Workflow automation: Designing agent-driven workflows that are driving real impact for the business and our customers - Search: Building semantic + keyword retrieval over large amounts of data - Knowledge graph: Modeling relationships between people, companies, topics, and interactions to power recommendations and discovery - New products: 0-1 work across new interaction types and mediums

Stack: TypeScript, Node, Postgres, OpenSearch, Temporal | React, Next.js, Tailwind | AWS

Kato | Senior Software Engineer | San Francisco, CA | ONSITE | Full-time Kato is building a compliance-first AI servicing platform for the $24B lending market. While others treat regulatory guardrails as an afterthought, we’ve built a regulatory rules system with an AI decision engine on top. Our first product is a Voice AI agent currently handling loan servicing calls for major fintechs like Bilt Rewards and Parafin.

We are backed by Pear VC and angels from Brex, Bridge, and Square. You’ll be our second engineering hire, working directly with our CTO (ex-Google/Brex EM) and CEO (ex-Goldman/Brex).

Infra: AWS, Terraform, Kubernetes, Docker

AI/ML: LLMs, Speech-to-Text, Text-to-Speech

Requirements:

2-5 years of production software experience.

Strong API design and architectural thinking.

An "owner's mindset"—we are a small, high-intensity team where everyone drives product direction.

Experience with WebRTC, real-time audio, or FinTech is a plus but not required.

Location: San Francisco (4 days/week in-person).

Waypoint AI | Senior Backend, Fullstack, Frontend | Prague + REMOTE (CZ) | Full-time | Equity

We're building Chip — an AI support engineer that autonomously triages, routes, and resolves complex technical support cases. Think: a teammate that reads every Jira ticket, every Intercom thread, and every runbook, then actually acts on them.

Czech-American B2B startup, raised $3.1M. Already in production with Volvo, ClickHouse, and others.

We're a small eng team where early architectural decisions still matter. We use AI daily as a collaborator (Claude Code) — not as a gimmick, but because it genuinely makes us faster. We value craft, ownership, and shipping in small slices.

Stack: Django + Django Ninja, Postgres, Dramatiq (background jobs), React/Next.js/TypeScript/Tailwind.

Hiring for three roles:

Senior Backend Engineer (AI Systems) — Own APIs, data pipelines, and durable workflows. LLM product experience (evals, cost/latency, vector search) is a plus. https://mywaypoint.ai/open-positions/senior-backend-engineer...

Fullstack Engineer — Backend-heavy with enough frontend to be dangerous. End-to-end ownership from schema to UI. https://mywaypoint.ai/open-positions/fullstack-engineer

Frontend Developer — Build interfaces that make complex AI feel simple. React/Next.js/TS/Tailwind. Product-minded, not just pixel-pushing. https://mywaypoint.ai/open-positions/frontend-developer

Office in Prague 7 (Holešovice), remote-friendly. Competitive CZ-market comp + meaningful equity.

To apply: joinus@mywaypoint.ai — include a project you shipped end-to-end and how you use AI tooling in your workflow. Mention HN.
