neoshare | Senior Product Engineers (AI) | Germany (Munich, Frankfurt, Berlin) | HYBRID (3+ days/week onsite) | Full-time | https://neoshare.com

neoshare builds software for banking and real estate: complex financing workflows, property valuation and market intelligence, and corporate ownership analysis.

We're hiring engineers for teams of up to four people, each owning a product or part of our shared platform. The team handles customer problems, product decisions, design, implementation and production. Work ranges from permissions and data infrastructure to financial domain logic and user interfaces.

Looking for people who have shipped products and are strong across disciplines: full-stack engineers with product sense, design engineers, and backend/platform engineers who care about how their systems are used.

We use LLMs throughout development, from exploring codebases to implementing and testing features. You should be comfortable directing them, reviewing their work, and taking responsibility for what ships.

German preferred, especially for customer-facing work; but not a must.

Hiring process: intro call, a 90-minute product exercise with your own tools, and a joint review.

Apply: product-jobs@neoshare.com. Send a few links to things you've built and a short note on your contribution.

You will be the second person in our AI team: what you build and how you build it becomes how Metcor does AI.

Your budget for AI tools is unlimited, as long as you can show the business outcomes.

Note: we are a "real" engineering company with depots and hi-vis vests and trucks (not that software engineering isn't real).

Tahoma AI | tahoma.io | Austin, TX or Seattle, WA (ONSITE optional) | REMOTE (US) | Full-time | Founding Engineer

Tahoma builds AI agents that automate healthcare Revenue Cycle Management (RCM): eligibility, claim status, claim submission, denials, and payment posting. We're live in production with paying enterprise customers.

Our agents operate payer portals behind MFA, green-screen terminals over SSH, and Windows desktop software, where some actions are irreversible. They run on a deterministic orchestration layer we built in-house, with model calls as bounded steps, not the control loop.

Stack: TypeScript/Node.js, Playwright, computer-use agents, Claude, Postgres, Azure, K8s.

You'll get to own the core platform end to end and make the real architecture calls: resilience to portal changes, exactly-once guarantees, observability, and cost per run.

Team: Founder from AWS, the former UnitedHealthcare CIO, advisors from Microsoft Research and Shopify's AI team, and a remote engineering team in-flight.

Please write us at careers@tahoma.io with your resume and one thing you've shipped. You can see more at https://www.tahoma.io/careers

AI x Healthcare Startup | bracehealth.com | Boston, MA Onsite | Full-time | Early Engineer

We're looking for a backend-leaning fullstack dev. You will be one of the first engineers outside of the founding team. Here is a bit more about us: We're a seed stage AI startup backed by top tier investors. We're on a mission to ensure every patient gets covered for the care they need and every doctor gets paid for the work they do.

We’re building deep, vertically integrated technology systems to solve fundamental problems in US healthcare - the biggest market in the world ($5T). We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!

We are a founding team made up of ex-YC, Amazon, Meta, Microsoft, and Harvard Business School with previous successful exits.

You’ll own entire product areas and be expected to play a true full-stack role, with the ability to go from customer need to end-state product. You’ll work directly with the CTO at the edge of what's possible with LLMs and agentic systems applied to a hard domain. You'll contribute to technical strategy, make real architectural decisions, and write vast amounts of production code with AI first developer workflows. Most importantly, the technology you build will have real impact on real people - clinics staying open, clinicians getting paid, patients getting care.

This is an opportunity to work in a fast paced, high ownership environment while solving real problems in healthcare.

We're happy to share more details on the role in person/on zoom. Please fill out this form if interested!

Ambito (ambito.io) — Founding AI Engineer / Equity Partner — Remote

Ambito is a CRM-connected QBR generator for B2B sales teams. The product is live, with the sales module, template engine, and CRM integrations already built.

We're looking for a founding AI engineer to make the product significantly smarter and broader. This is an equity-only role initially (10+ hrs/week), working directly with the founders and our existing technical partner.

You'll work on:

AI product features: Build a native assistant that can answer questions about customer data, surface trends, provide setup guidance, and help generate QBRs. Retrieval, tool use, structured-data queries, evals, and cost control.

Customer Success: Extend the existing framework into account reviews, renewals, and customer health.

Integrations: Harden and expand CRM/CS integrations (Salesforce, HubSpot, etc.).

Product: Make the overall experience faster, simpler, and more AI-native where it actually helps.

We're looking for someone who has shipped LLM features in production, not just demos, and is comfortable with retrieval, embeddings, tool calling, agent workflows, and evaluation. You should also be able to work across React, TypeScript, and Node (Firebase experience is a plus).

You should think like a product engineer: turn varied customer requests into simple, flexible systems and work independently. Sales tech / RevOps / CS experience is a plus. Boston/MA is a plus.

To apply: Send a short note with something you've built using AI and why this problem interests you. No cover letter. LinkedIn or contact@ambito.io.
