Hearo is building an AI platform that turns public internet conversations (Reddit, app reviews, online communities) into structured product intelligence. The goal is to help founders and product teams understand what users actually think about products by analyzing discussions at scale.
We’re looking for a founding engineer to help build the first version of the platform.
The core technical work involves ingesting large volumes of public conversation data, building reliable async data pipelines, and implementing retrieval-augmented generation (RAG) systems that transform noisy discussions into useful insights like product pain points, feature requests, sentiment trends, and competitor signals.
Tech stack is flexible but will likely involve Python or Node.js, Postgres, vector search (pgvector/Pinecone), and LLM APIs (OpenAI/Anthropic). Experience with backend systems, APIs, scraping, or data pipelines is especially valuable. Experience building LLM or RAG systems is a strong plus.
We’re looking for someone who enjoys early-stage product building and is comfortable owning systems end-to-end.

Spruce builds the operating system for heat pump installation businesses across the UK. The UK needs to install 600,000 heat pumps a year to hit net zero by 2050 — right now we're at ~100,000. We're building the software to close that gap, supporting 500+ installers and growing fast. Founded early 2024, VC-backed.
The problems are genuinely interesting: 2D floor-plan geometry and drawing tools, offline-first PWAs with sync conflict resolution, cross-company job sharing with RBAC permissions, underfloor heating physics and hydronics calculations, LiDAR integration, and solar and battery systems.
Stack: TypeScript, React, Node.js, PostgreSQL/PostGIS, Prisma, Docker, Konva, Tailwind.
You'd own slices of architecture and technical strategy, write high-leverage code on critical paths, and mentor a growing engineering team — while still spending most of your time hands-on.
Looking for someone strong in TypeScript across the full stack, who's product-minded and wants real ownership over what they build.

Flutter is used by millions of devs (and nearly ⅓ of free apps submitted to AppStore), but is missing services for businesses. I built Flutter at Google. Now we’ve built a company selling services to 1000s of Flutter-using businesses globally, on track to profitability this year.
We serve 100s of millions of devices from our cloud, (2k+ RPS sustained), built mostly in Dart on Google Cloud + CloudFlare. We’re in the process of launching a series of CI offerings and have a lot of cloud development work ahead of us. You need production cloud experience, want to work at a startup, and be up for the challenge of owning, developing, and expanding Shorebird’s cloud infrastructure and backend services including code, configuration, architecture, and more. Previous Dart experience is not required.
We’re a small, senior team, making something people want. Tech: GCP, Cloudflare, Dart, Postgres, a little React & Node. Shorebird operates almost entirely in the public over Discord. https://discord.gg/shorebird
Decise is a hands-on advisory and delivery firm that helps organizations unlock the full value of their technology and improve business profitability.
We work directly with executives to define what should be built, then we build it. Our work spans software engineering, data platforms, analytics, and customer-facing digital products. We often operate as fractional CIOs and CTOs, guiding both the strategic direction and the technical execution of our clients’ technology initiatives.
Our clients rely on us to turn complex business problems into working systems — not slide decks.
We are intentionally small and senior. Everyone on the team is a builder who can operate independently, solve complex problems, and deliver finished systems that people actually use.
White-glove service. Blue-collar grit.
We’re looking for a principal-level technologist who can move between engineering, architecture, and client strategy. Most of your time will be spent building systems and writing production code. The rest will involve working directly with executives to shape technical direction and ensure the work creates real business value.
Typical technologies we work with include React, Angular, Next.js, Node.js, Go, Snowflake, SQL, dbt, Domo, Streamlit, AWS, Vercel, and modern AI-assisted engineering tools. The exact stack varies by client; the ability to learn quickly and move confidently across technologies matters more than any specific tool.
Strong candidates typically have 10–15 years of experience building production systems and are comfortable operating both as hands-on engineers and as technical advisors to executives.
This is a long-term, full-time independent contractor engagement (1099). Everyone at Decise — including the founders — operates in this structure. Compensation is designed to be competitive with senior engineering roles at leading technology companies.
The fastest way to stand out is to show us something you’ve built: a production system, GitHub repository, application, or data platform you designed.

1. Hiring: OS / Device Lifecycle Engineer (Secure Boot / OTA / Identity) (Remote, UK/EU preferred)
We already run RTSP + inference. Now we need the person who owns several year device reality.
You will own (single layer ownership): Secure boot / trust chain (ROM → U-Boot → kernel → rootfs) OTA updates + rollback strategy (A/B, recovery modes) Device identity & lifecycle (provisioning, key rotation) Failure recovery (power loss, corrupted SD, watchdogs)
You must be able to answer directly: SD vs eMMC vs NVMe tradeoffs + corruption mitigation Brown-out behavior, thermal throttling, BSP maturity Camera ISP/NPU concurrency constraints + vendor SDK realities
2. Hiring: Independent Embedded/Firmware Engineer (Bring-up Audit & Stability) (Remote UK/EU preferred)
We’re shipping on real hardware. Reliability beats elegance. We need a senior embedded engineer to audit and validate our assumptions and prevent single-point-of-failure risk.
You will own: Independent review of firmware/bring-up assumptions Validation of performance, thermals, power behavior, stability Reproducible test plans (what breaks, how to detect, how to recover) Documentation that prevents knowledge living in one head
If you’ve shipped embedded systems that survive ugly reality (packet loss, unplugging, thermal throttling, storage corruption), we want to talk.

I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled.
Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate. Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.
Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.
This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.
We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.
Reach out directly with your resume and why you want this position to lucie@markerlearning.com. Make the subject "Lead Engineer Application (I am not a bot)".
Flux developed the first AI Hardware Engineer integrated into a browser-based EDA, where hardware engineers can collaborate live and design hardware together from around the world. Our goal is to democratize the ability to create bleeding edge hardware, and revolutionize how electronics are designed and built.
Our agent isn’t an AI “assistant” bolted onto a legacy CAD tool. It’s built deeply into the system: you give it a job, it proposes a plan, explains decisions, and executes real workflows inside the editor: selecting parts, generating schematics, placing and routing with awareness of constraints, and running checks along the way. It works transparently, seeks feedback, and gets better over time by learning its user’s standards and preferences.
