AREO | Remote (EU) | Full-Time | Equity | Roles: [Engineering Manager (Ruby on Rails), Lead Product Engineer (Ruby on Rails)]

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.

About a year ago we brought a backend developer on board 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 highly preferred.

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.

Formical | Software Engineer | ONSITE (Hybrid - Delft, Netherlands) | Full-time | https://careers.formical.bio

At Formical, we believe we can become the first sustainable generation on Earth. Biotechnology plays a key role in this future - benefiting all people, animals, and our planet by making industrial production more sustainable. But bioprocessing still runs on fragmented data and tacit knowledge. The infrastructure to turn data into the intelligence that teams need to scale doesn't exist yet, hindering the sector’s progress. Our product accelerates bioprocessing by connecting fragmented data, enabling predictive modeling, and ultimately closing the loop between measurement and action.

We're not looking for specific skills, just willingness to learn. I joined a couple months ago with little React/TypeScript full-stack experience, but with CC I managed quite well coming from a Python backend background. Nothing's enforced though! We're a small team, have some customers, and are looking to build out the platform and the client-base significantly this year.

We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures. The system enforces consistency across them, and propagates uncertainty through each step. Our first applications are in finance and scientific research, with use cases ranging from equity valuation and distress monitoring, to particle physics.

This is an opportunity for builders and practitioners to help shape a deep-tech product from its earliest stage.

Current openings:

* Product Software Engineering (Quantitative Modeling)

* Program Synthesis Engineering

* Applied Category Theory Research

* Bayesian Software Engineering

We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.

Common Prefix | Software Engineers - Auditors - Support Engineers - Formal Verification Engineer | Greece - Remote – Full-Time

Common Prefix is a science-first blockchain consulting company. Our vision is to make blockchains usable for mainstream users and everyday people – paying at the supermarket, remittances, moving money across borders, saving, investing – and solving the real problems of usability, scalability, and interoperability that come with it.

We're a 30-person team, half scientists (cryptographer PhDs, post-docs, and professors) from renowned universities, half engineers with long web2 experience. A lot of our field is broken and we're trying to make a small contribution in fixing it, by introducing provable security and proper engineering practices across the board.

What we're looking for: Software engineers who can solve problems, are smart, get things done, and enjoy working on the bleeding edge, learning about cryptography, and working from first-principles. Auditors who can write and read code, especially low-level cryptographic implementation code (zero knowledge verifiers, signature schemes, etc), consensus (PoW, PoS), or smart contracts (everything DeFi). Support engineers (junior to early-mid) who enjoy being on the front line of production support (monitor live systems, respond to partner/user issues, triage/debug, and escalate). Formal Verification Engineers with hands-on experience in formal methods to work on machine-checked proofs of blockchain protocols and smart contracts.

Tech stack: Doesn't matter, we'll teach you. But we work mostly with Rust.

Open roles:

* Software Engineer, https://commonprefix.notion.site/sw-folk

* Auditor, https://commonprefix.notion.site/auditing-folk

* Support Engineer, https://commonprefix.notion.site/support-folk

* Formal Verification Engineer, https://commonprefix.notion.site/fve-folk

We offer:

* $80,000–$171,000 / year cash

* Local from Athens, Greece, or remote

* Conference participation in exciting scientific and engineering venues, 2-3 times per year

* The opportunity to work and learn from world-class scientists from major universities in the field of blockchains, cryptography, and consensus

Volcore | Manchester, UK | On-site | Full-Time | Software Engineer, Forecaster, Mathematical Modelling Developer

At Volcore, we model the electricity system to do proprietary trading that helps balance the grid and facilitate renewables integration. Our technical roles are a blend of Software Engineering and Data Science, wherein we solve problems end-to-end, from data ingestion and analysis to optimisation and deployment. Often these require novel solutions, drawing on original research and experimentation. We are a profitable and ambitious scale-up looking for people who can both crack these kinds of problems and continually improve our shared libraries, tooling and workflows to ensure they are fast, accurate and a delight to work with.

Our team are close-knit, with minimal hierarchy and almost zero meetings. We work together in-office to whiteboard solutions together and everything we build is used by people sitting next to us.

Typically these positions attract talented people looking to build a career out of solving challenging computational problems; and/or people who have outgrown their previous role and are seeking more responsibility or more challenging subject matter. Every team member owns important projects very early on, and if you can deliver value in a particular area, you’ll be recognised and rewarded for it, regardless of job title.

Our tech stack includes Python, backend Typescript, Postgres and Rust.

We review all applications personally. For more info, including our requirements and salaries:
