9 Mothers Defense | Robotics / Audio Engineers | Austin TX | Full-time | ONSITE

We're building AI-driven turrets that stop hostile drones - where robotics needs F1-level speed.

We're looking for smart, T-shaped teammates: people who are experts in one area but happy to jump in wherever needed. Our software team is small, so every member makes a real impact.

If you want to write motor control in Rust, optimize camera processing with custom CUDA kernels on Jetson, or rework a transformer-based tracker to handle small objects - you can do that here, and much more.

TrueSpace | Full-Stack Engineer | Denver, CO | Hybrid / Remote

TrueSpace helps make second-stage businesses better. We're building TrueScore, a metric to assess a company's ability to scale, and Trudy, an agent to help CEOs improve that metric.

You'd join a small team of experienced founders and operators and help build features like onboarding, Stripe billing, org admin, and our agent. We're a small tech team, so you'd also help with CI/CD, lightweight DevOps, and AWS infrastructure.

Our current tech stack is simple and open to change: Laravel/PHP backend, alpinejs, mysql, and Bedrock on AWS.

You'll be successful in this role if you're a solid engineer and web developer, can read and write sql, and have some experience with tools and libraries like the ones we use--you needn't know exactly our stack.

Denver-based preferred. Competitive salary. Medical/dental/vision benefits, 401K match up to 4%. Sorry, no Visa sponsorship at this time.

Sentinel Defense Technologies | Remote (Global) | Equity → Pre-Seed in 6-10 Weeks

We are building an AI-powered civilian protection platform — real-time threat intelligence for non-combatants in conflict zones. Think Waze for airstrikes. Multi-model AI pipeline (Gemini) ingests OSINT, verifies it through gated analysis, and pushes geolocated alerts to offline-first mobile clients. People die when information is late or wrong — we are solving both problems.

We are currently unfunded, operating on sweat equity. Pre-seed is 6-10 weeks out. This is not a side project — we have a working system, a pipeline of 39 vetted applicants, and a founder who has been shipping code daily for months. But I will not sugarcoat it: right now, this is nights-and-weekends until funding closes.

*We need two people:*

*1. Systems Architect / Full Stack Dev* You see the whole board. You think in pipelines, failure modes, and deployment constraints — not just endpoints. You will own the technical architecture of a system where a bug isn't a bad UX, it's a missed warning. Python/Django, MongoDB, LLMs (Gemini/Vertex AI). Bonus: Flutter, OSINT, geospatial.

*2. Implementation Partner / Full Stack Dev* You ship. Relentlessly. You take a spec and it's done by morning. You don't wait for perfect — you build, test, push, iterate. Same stack: Python/Django, MongoDB. You will be the person who turns architecture into working product at startup speed.

Both roles require exceptional drive. This is a founding team — not a job listing.

*Compensation (No BS):* - *Now:* Sweat equity only. You're building your stake. - *Pre-Seed (6-10 weeks):* $3,000/month + equity per contributor. - *Seed (6-12 months):* 75% market salary + equity. Increases from there.

If you need full salary today, this is not for you. If you want to build something that actually matters and you're willing to bet on yourself for 6-10 weeks to get there — keep reading.

*Stack:* Python, Django 4.1, MongoDB, Flutter, Vertex AI (Gemini), Docker, AWS.

*Apply:* PeterJFrancoIII@gmail.com — Send your resume or GitHub and tell me what you'd ship in your first week.

Estuary | US-Based / Remote | Full-time – https://estuary.dev/

Estuary is a VC-backed, post–Series A startup powering right-time data replication and transform — from sub-second CDC replication to terabyte-scale OLAP data flows.

We’re open-source, developer-first, and focused on making data movement radically simpler across both our Platform and Applications layers.

We’re hiring for:

Senior & Staff Backend Engineers

5+ years backend experience; Go required, Rust a plus. Own core systems powering real-time data pipelines. Build complex API/database integrations, improve connector frameworks, and tackle deep challenges in performance, reliability, and developer experience.

Backend Engineer (Integrations) – 2–4 years of backend experience. Help expand and maintain our catalog of real-time data connectors to SaaS tools using Python. You’ll work closely with experienced engineers to build and optimize integrations with third-party systems, while deepening your skills in infrastructure and stream processing.

Solutions Engineer - Work with the founding team to help customers use Estuary effectively. Collaborate closely with engineering and product, shape how users integrate real-time data, and feed insights back into product development.

What we’re looking for: Engineers who care about building reliable, maintainable systems and enjoy working with complex APIs and data flows. We value curiosity, clear communication, and a willingness to learn.

Bonus points for experience with CDC tools, open source contributions, or fast-paced startups.

To apply: Email your resume to careers@estuary.dev

Di Rezze Family Office | AI-Native Technical Operations Lead | Miami, FL (ONSITE) | $130K-$200K + Early Equity | Full-Time

We're building an AI-native clinical data platform from the ground up, not a legacy system with AI bolted on. AI is core to the architecture, the development workflow, and the product itself. Fully funded by a private family office, no outside capital needed, no fundraising runway concerns. We're assembling the founding team now.

We're building a founding team to revolutionize healthcare in the United States, and we're hiring a technical operations lead. Best analogy: studio engineer to a recording artist. You own the environment so engineering leadership stays on high-leverage product work. That means CI/CD, QA, testing infrastructure, compliance documentation, and 30-40% independent feature development. Ground-floor equity in a company that's pre-revenue by choice, not by circumstance.

Hard requirement: you are already shipping software with AI coding tools daily (Claude Code, Cursor, Copilot, or similar). Not curious about AI. Not experimenting. Actively building and deploying with it. If you can't show us something you built with AI tools in the last 60 days, this isn't the right fit. Stack: React/Next.js, Python, PostgreSQL, Docker, AWS. But we care more about polyglot instincts than any single framework.

What we're looking for:

3-7 years full-stack experience Strong QA discipline (you write tests because you want to, not because someone made you) DevOps comfort: Docker, CI/CD pipelines, cloud infrastructure Self-directed. We don't micromanage and don't plan to start. Must be US-based or already have US work authorization. We do not sponsor visas.

What you get:

Meaningful early-stage equity (not a token option grant)

Direct access to founders and decision-makers, no layers

A say in the technical architecture from day one

Relocation to Miami fully covered

Health, dental, vision

Interview process: 15-min screen (show us your AI-built work) > take-home exercise > 2-hour paid working session > culture fit conversation.

Email: jpd@direzzefamilyoffice.com, subject line "HN March 2026" so I can find you.

Tangible Materials | AI Engineer | Remote (US/Canada) | Full-time | $140k - $160k USD + equity at seed startup.

Tangible Materials helps the construction industry to make better decisions around building materials. This means using less and better materials. We use AI to parse very complex construction documents to estimate quantities, track design decisions and detect over-design.

In this role, you'll help build the next version of our core technology by creating an agentic takeoff system.

Stack: Ruby, Rails, Typescript, React, Postgres, Redis.

Bloomberg | Senior Software Engineer | Hybrid (NYC) | Full-time | $160k - $240k USD + bonus

Every day, Bloomberg’s clients rely on secure and seamless access to our products. Our team makes that possible by building infrastructure that verifies identities for both clients and employees. We design systems that are fast, resilient, and highly available, capable of handling large volumes of authentication traffic around the clock.

You can expect to

- Lead design and development of Bloomberg’s next-generation authentication and MFA systems, aligning with future product goals

- Create scalable, end-to-end identity solutions across web, API, and proprietary technologies

- Collaborate with cross-functional partners across product, design, and engineering
