Annex | Backend + Data Engineer | Bay Area, Austin | Full-time

The cost of homeowners insurance, especially in natural catastrophe prone areas, has skyrocketed in recent years. Annex is solving this problem with better digital infrastructure for executing the transaction. Our platform enables insurance agents to quote and bind policies within 90 seconds vs. the current multi-day phone/email/fax-based transaction that is the status quo.

We grew 4x in 2025 and anticipate similar growth in 2026. We've done the above after deploying <$1.5m in funding. We have significant and growing momentum on both the insurance distribution and insurance capital sides of our business; our challenge now is scaling our engineering team to support that progress.

We're in that exciting early stage, where someone can contribute foundational new pieces to core parts of our platform.

Positron | Bootstrapping Startup | South Korea | Co-founder

Equity-only co-founders. If you must take a salary position, send us a resume with "Salary only" and we'll check back later.

We're developing an efficient social-decision model so that communities can organize social-finance campaigns and effectively administrate funds without being beholden to one creator. Keeping funds in the hands of backers creates accountability and is one key to taking social finance to the next level.

We say that our social tech "makes the money smarter." It will do this by making communities smarter. How we do social will change how every future social platform gets built and will upset every social product on the market. Society will benefit tremendously from the more coherent discourse.

To bootstrap our platform, we are developing an music visualizer called MuTate. It will soon be powered by our in-house machine learning tricks, which do not rely on back-propagation in order to enable radical forward architectures that are smaller and easier to develop and train. This work directly impacts our mission and aligns us both with consumer enthusiasm for small & local AI to run outside the cloud and with people working on hard problems that need AI tool-kits they can embed their own world models within.

We are using PrizeForge as a better kind of Patreon while we finish our crowd cognition implementation and start to integrate social decisions with our existing social finance.

Our entire tech stack is Rust where possible. We use Leptos, Axum, Postgres with SQLx. It's like a full-stack typescript setup, but with Rust and WASM. MuTate uses Rust, the Vulkan API, and Slang.

Anyone who materially accelerates the trajectory of the company will participate proportionately in the rewards. Our work on MuTate will put us default-viable. Our work on crowd cognition and community-organized campaigns will likewise make use default-viable.

Prototype two-dimensional fund raising: https://prizeforge.com Career listings with more details: https://positron.solutions/careers MuTate Github repo: github.com/positron-solutions/mutate

Korean language skill is optional but anticipate learning business Korean and translating a lot. Same timezone is as far as will be considered remote unless you're physically stuck in Ukraine etc and begin by contributing on MuTate.

Source (https://source.network)| USA/Canada: REMOTE | Full-Time | https://careers.source.network

Our mission is to make it normal, not heroic, for edge AI, mobile apps, and critical software to run close to where data is born: on devices, in vehicles, in field hardware, not just in a distant GPU farm. We’re building the data and trust layer that lets developers ship systems that still behave correctly when links are flaky, latency is awful, and the cloud is optional instead of mandatory—instead of the usual “SQLite everywhere + ad-hoc sync” duct tape.

We’re growing fast and are looking to fill the following positions:

We're looking for a hands-on Senior Full Stack Developer to help design and deliver core product experiences across our stack (TypeScript + NestJS on the backend and Next.js on the frontend.) You'll work on customer-facing workflows, turning ambiguity into shippable slices, and helping us level up reliability, security, and speed as we scale.

What you'll do:

    - Build features: implement and ship production ready functionality across frontend and backend (TypeScript, Next.js, NestJS).

    - Backend: contribute heavily to APIs, data models, and integrations that power questionnaire-driven workflows and FHIR pipelines.

    - Frontend: build intuitive, configurable UI modules for complex healthcare workflows, collaborate closely with Product and domain experts.

    - Quality & reliability: contribute to testing strategy (unit/integration/contract/E2E), safe migrations, and rollouts (feature flags).

    - Observability & performance: instrument tracing/metrics/logging, improve dashboards/alerts, and participate in incident reviews and follow-ups.
    - Engineering excellence: raise the bar through strong code reviews, pragmatic standards, and improvements to the developer experience.

    - FHIR correctness: help ensure backend transformations produce valid FHIR resources in Medplum and support scalable data flows.

    - 7+ years building production web applications (frontend + backend) in a fast-moving environment.

    - Strong TypeScript + Node.js experience and solid production exposure to NestJS (or comparable backend frameworks with willingness to ramp quickly).

    - Strong experience with modern React-based frontend development (React / Next.js) and comfort owning UI implementation details.

    - Experience shipping ambiguous projects end-to-end with good judgment, pragmatism, and clear communication.

    - Familiar with building secure systems and thoughtful about reliability, testing, and performance.

    - Experience with FHIR / Medplum, healthcare data workflows, or LIMS/clinical systems.

    - Familiarity with HIPAA and/or SOC 2 practices.

    - AWS experience (e.g., Cognito, Fargate) and comfort working in cloud-native environments.

How to apply: Email hiring [@] pelairo.com and mention "HN Who's Hiring January 2026." (We know our website needs some work, but the product is our priority right now.)

Ionworks | Founding Systems Engineer | Remote (US) or Pittsburgh, PA | Full-time Ionworks builds battery simulation and optimization software used by R&D teams designing next-generation batteries.
