We believe AI should amplify the creativity of everyone who builds software, not just speed up tasks. If you’re technical, curious, customer-driven, and want to shape how the next generation of software is created, we’d be thrilled to work with you.

Our Product Security org works across application and infrastructure security, security design and architecture reviews, and vulnerability management. We partner closely with engineering teams to identify, prioritize, and remediate risk early, with an emphasis on making security practical, embedded in everyday development, and useful to the teams building Chime’s products. If you’re excited about being on the front lines of securing both AI and financial technology, this is a particularly interesting place to do that work. We currently have Senior Application Security Engineer, Product Security Engineer, and Manager - Product Security open.

Tenera | San Francisco, CA | Onsite | Founding Engineer (Full-Time)

Tenera (https://trytenera.ai) is building the product decision layer for agents and humans, backed by a top tier VC (announcing soon). We help teams validate what they build across the entire software development lifecycle, grounding AI personas in real user behavior and business context, then proving them out by replaying past product decisions.

We are a small, exceptionally talented team (ex-Amazon, Nvidia, Uber, Stanford, CMU) hiring our first engineer. We work onsite in SF five days a week (open to relocation for the right person) and offer meaningful founding equity.

This is an unconventional role. We want an "agent-native" engineer. If you are still writing every function by hand, this isn't for you. You will orchestrate multiple coding agents in parallel, managing worktrees, concurrency, and shared context, while owning the architecture decisions that matter most: big data pipelines, schema design, system tradeoffs, and evals.

Requirements: 3+ years shipping full-stack apps, comfortable with LLM infrastructure and tracing, fluent with git worktrees and isolated workspaces, and strong product taste. Active GitHub contributors preferred.

Interested? Email: suzie@trytenera.ai

Emergences Labs (emergences.ai) | AI / Systems Engineer — NeoHuman | REMOTE (US) | Full-time | $120K-$150K + equity | Visa sponsorship available

We're a small, research-driven, VC-backed team building NeoHuman: a desktop-first system that observes how people actually use AI tools, files, and workflows during real tasks, and turns those sessions into reliable evaluation evidence. We care about the process, not just the final answer — what someone typed, what they copied, what they verified, how they moved across apps.

We've published the AgentIF-OneDay benchmark. Now we're scaling the capture and evaluation infrastructure underneath it.

You'd own: - Cross-platform desktop capture across macOS + Windows (AX/UIA trees, OCR, clipboard, keyboard/mouse boundaries, file interactions) - Trace fusion — turning noisy low-level signals into clean human-readable session timelines - The evaluation evidence pipeline (data model, ingestion, exports) - LLM normalization that summarizes traces without hallucinating or hiding evidence quality - Privacy/consent/proctoring safety for enterprise customers

We want an AI-native engineer: - 3+ years shipping production TypeScript + Node.js - Built or shipped Electron + native helpers - Strong PostgreSQL (schema design, indexing, data quality) - Comfortable with OS APIs, permissions, background processes - Hands-on LLM API experience (structured output, evaluation, hallucination control) - Uses Claude Code, Cursor, or similar as a daily working medium — not a side experiment - Bonus: macOS AX / ScreenCaptureKit / CGEventTap, Windows UIA, or you've studied/built things like Screenpipe, OpenAdapt, Rewind, OpenChronicle

Stack: TypeScript · Node.js · Electron · native macOS/Windows · Next.js 15 · React 19 · Postgres + Supabase · OCR · Accessibility APIs · OpenAI / Anthropic / Gemini · Vercel · GitHub Actions

Why us: Hard, unusual problem at the boundary of OS internals, multimodal capture, and AI evaluation. Small team, technical founders who code daily, real ownership of the capture stack. We hire on demonstrated capability, not credentials.

Apply: email jack@emergences.ai with your resume and a brief note about a system you've built — desktop software, AI infra, data pipelines, evaluation, or low-level debugging. Subject: "Your Name — AI / Systems Engineer". Please mention HN in the email.
