Aqora | Paris, France / US / Remote (EU) | Multiple roles | https://aqora.io

Aqora is the "Hugging Face for quantum computing". We host datasets, benchmarks, and use-case challenges, plus the orchestration layer to run quantum algorithms and workflows across hardware backends, so results are reproducible, comparable, and actually move the field forward. We grew out of the QuantX hackathons at École Polytechnique and now run competitions and a public datasets hub for partners across pharma, finance, energy, and defense.

We're hiring:

* Senior Full Stack Software Engineer. Build the platform end to end: datasets hub, challenges, leaderboards, and the workflow engine that orchestrates quantum jobs across backends. You own features from schema to UI and care about developer experience. Bonus: data, ML, or research-platform experience.

* Quantum Computing Expert. Design challenges, curate datasets, define benchmarks, and shape how algorithms and workflows run on the platform. Work directly with enterprise partners to translate their problems into something the community can solve. PhD or equivalent depth in quantum algorithms, QML, or optimization.

* Chief Commercial Officer, US. Own US go-to-market end to end: strategy, enterprise pipeline, team build-out. You've scaled commercial functions at a deep-tech, dev-tools, or research-platform company. Based in the US.

* Head of Marketing. Positioning, demand gen, and brand for a category still being defined. B2B technical marketing background required; quantum experience welcome but not necessary, curiosity is.

* Product Manager. Drive the roadmap across the datasets hub, challenges platform, benchmarks, and workflow orchestration. Strong technical instincts and experience shipping developer or research-facing products.

* Sales, EU. Enterprise sales into R&D and innovation teams across Europe. Long, technical sales cycles, consultative selling, comfort talking to PhDs and procurement on the same day. EU-based, remote.

Reach out to jannes[at]aqora.io with a short note on why this problem space and what you've built or sold before.

PlantingSpace | Full-time | Remote (EU time zone) + Quarterly Meet-ups | https://planting.space

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.

We’re building out our team in the following areas:

* Product Software Engineering (Quantitative Modeling) * Program Synthesis Engineering * Applied Category Theory Research * Bayesian Software Engineering * Finance Operations (Accounting, Analytics & Workforce)

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.

Fortech Engineering | Full Stack Software Engineer | Primarily remote (Waterloo region, Canada) | $140-170K CAD + performance pay + earned equity

Electrical and mechanical engineering consulting firm in Waterloo, serving the Canadian building construction industry — a market that's still mostly designed the old way. I designed the original platform schema and UX vision; my early code attempts got abandoned when running and growing the firm took priority. The years since have been spent figuring out how to scale this properly and fill those gaps. We're now at the depth and size to support a real build — with no committee in the way, and with my time properly committed to it this time. I'm hiring an exceptional software engineer to take it to the production platform it was always meant to be.

Real users, direct collaboration with the founder, and 20 years of MEP practice plus the platform vision. Few founders building automation in this space bring both.

Profitable, bootstrapped, 18 years old. Equity is earned, not granted — a real cut of a real business, not options in something that may or may not happen.

Stack: TypeScript, React, Tailwind, shadcn/ui, AG Grid, TanStack Query, Drizzle, PostgreSQL, Python (FastAPI), Node.js, Docker.

Looking for: full-stack, agentic-first as a daily working mode, shipper not writer.

Apply: jacri@fortecheng.com More: https://fortecheng.com/careers

Project Debug | General Engineer | Singapore (HYBRID) | Full-time | debug.com

Project Debug raises, sorts by sex, and releases millions of (non-biting) male mosquitoes in Singapore to reduce the local mosquito population and prevent the spread of dengue and other mosquito-borne illnesses. Our trial in Fresno, CA showed a 95% reduction in female mosquitoes during the seasonal peak.

Our engineering team is pretty small and we need a solid generalist engineer who is interested in becoming a domain expert in our factory, where we do automated rearing and sex sorting. If you run a homelab, have tinkered with Arduino, and can prompt/write some Python, we can teach you everything you need to know about our stack (Go, Python, React, Kubernetes, Tensorflow).

Reach out to katejm@debugproject.com and please mention HN in your email.

Conductor | San Francisco, ONSITE | Full-time

Conductor lets you run a team of coding agents on your Mac. We've grown 10x since January, and just recently announced our $22m Series A. We're a small team looking for exceptional software engineers and designers.

Hi! We're Ontix. We're building the business layer to connect siloed datasets and query them with natural language, offering insights to SMBs they couldn't get before. We're fully funded by our sibling company, and are looking for remote freelancers in the US and full-time, onsite employees in San Diego, California (if you're into that kind of thing). We're looking for experience in the following roles:

+ QA: We're looking for a QA engineer deeply familiar with the software lifecycle in the age of agentic coding. You'd have a lot of responsibility, but also the opportunity to define what solid QA looks like at Ontix.

+ Azure Cloud Engineer: We're a mostly-AWS shop, but we have a few potential customers that are deeply entrenched in the Azure ecosystem, including a migration from SharePoint to Fabric + OneLake. You'd be leading the charge on that.

+ Infosec + Automated Vulnerability Scanning: If you browse new CVEs over breakfast, we want to talk to you. There's a huge demand among our current customers for continuous vulnerability scanning, both in the codebase and on the deployed edge. We have some test platforms, but would love a more robust solution we can market.

+ Full-Stack WordPress Developer: Our sister company is a bit old school still: If you can parachute in to a PHP + Vue 2/3 + WordPress + AWS EC2 environment, we would love to pass on your number to them.

We're looking to grow quickly as our client base expands. Healthcare, vision, and 401(k) for FTEs. If you're interested in any of these roles, or would like more information in general about us, please visit https://ontix.io or email l33t@ontix.io with a few sentences describing your experience, interest, and where you're located.

Orenva | Senior Contract Engineer | Remote | Contract

Orenva is building governance infrastructure for founder-led businesses using AI — a multi-agent web system that keeps AI and human teams aligned with founder as work scales.

Likely Python or TypeScript; I'm open to your recommendation based on the spec. Multi-agent runtime, schema-first design, full-stack web, versioned outputs. Fixed-bid preferred; hourly with cap accepted. Subcontracting mid-grade under your senior oversight welcome.

Start is contingent on funding close. Estimated build: 3–6 months. Strong fit will become an ongoing technical lead / fractional CTO relationship.

You will have ownership through the entire stack from the database, through geostatistical backend services, through 3D rendering on the client side.

Work rooted in agentic systems, so an understanding of the internals of things like Claude Code, and a broader understanding of orchestrating agents to complete complex discrete tasks is important.

You: Fluent in Typescript, Python, and framework/tooling agnostic (Currently using things like NextJS, Supabase, Cesium) Eager to learn about mining domain knowledge around the software. Ownership of the codebase, and the systems that support the software (project management, CI/CD, monitoring, etc.) Open to doing a yearly month abroad with Neil and I. Last year, it was Oaxaca, Mexico.
