My name is Marius and I am the CTO at AREO (https://goareo.com/).
AREO, founded in January 2023 by a team with 20+ years of combined experience in retail and startups, is a young startup specializing in developing innovative solutions for supermarkets and grocery retail stores.
Our cutting-edge B2B SaaS platform optimizes workflows for employees by providing real-time access to inventory, product information, and customer inquiries. We serve large supermarket chains in Germany and across the EU.
We already hired two backend developers through "HN - Who is hiring" and are now seeking a Lead Product Engineer / Engineering Manager with a minimum of 8 years of experience (preferably in startups), as we just closed another large contract with a major retail chain and are growing quickly.
For both the Product Engineer and the Engineering Manager role professional knowledge of German is required.
If you're passionate about building innovative retail products from scratch, these roles are for you.
Backend Stack: Ruby / Rails (8.x), StimulusJS / Hotwire / Turbo, AlpineJS, Postgres, Docker, DigitalOcean, OpenAPI, LLMs
Perks: Fully remote roles (Europe), work where you are most productive, sizeable equity in a rapidly growing company, flat hierarchies, no-ego work environment, work in a lean but highly experienced team
Apply here: marius[at]goareo.com and mention “HN - Who is hiring?” and the role you are applying for in the subject.
YC is hiring Product Engineers to build the future of YC -- and increasingly, software for startups everywhere.
We're a team of ~20 engineers building everything from Work at a Startup and Demo Day to investor software, founder tools, AI systems, and new open source projects. We don't have PMs. Engineers talk to users, decide what to build, and ship quickly.
Some of what we've been building:
* New products: GStack rethinks the software stack for an AI-native world. GBrain explores persistent memory and knowledge systems for AI. Paxel and other AI-powered products help founders—and increasingly everyone else -- build software and companies faster.
* Products at scale: We build and operate Work at a Startup (2M+ candidates, 1000s of early startups), Demo Day, our investor marketplace, SAFE signing, founder CRM, and the software that powers YC itself.
* Data: YC has over 20 years of proprietary startup data. We're applying it to how we think about the future of YC's batch, fundraising tools, hiring, recommendations, and entirely new ways to help people start and grow successful companies.
AI has fundamentally changed how we build software, and we're looking for engineers who are already experimenting with coding agents, MCP, LLMs, context engineering, evals, developer tooling, and whatever comes next. Our stack includes Rails, React, Postgres, Python, TypeScript, LLM APIs, and plenty of experimental infrastructure, but we're much more interested in great builders than expertise in any particular framework.
We're in person in San Francisco (Dogpatch). You'll work closely with founders and alongside people like Garry, Jared and Diana, helping define how YC—and startups more broadly—build software in the AI era.
We offer competitive compensation, carry in the YC fund, and a small, high-autonomy engineering team.

When you look at the headers of major websites, you’ll see us. If it has to be performant, secure, scaled worldwide, and always-on, it uses Fastly.
We're a globally edge cloud platform for performance and security, emphasizing open standards, sustainable engineering, and resilience-by-design.
We're hiring across compute, security, platform engineering, network and edge protocols, release engineering, network architecture, client services engineering, and more.
Rather than building walled gardens, we co-founded the Bytecode Alliance, heavily upstream our work to open standards, actively author IETF drafts, and power the global infrastructure for open-source Python, Rust, Ruby, OpenStreetMap, and much more.
- The Stack: Rust, C/C++, Go, Javascript, Typescript, WebAssembly (Wasm/WASI), Wasmtime, Cranelift, eBPF/XDP, QUIC, HTTP, TLS, TCP, Varnish/VCL, Linux kernel internals, distributed systems, professional services.
