Alaffia Health is a Series B healthtech company in NYC fixing a real, expensive problem: US health plans lose billions every year to improper payments and administrative waste in claims processing. We combine clinicians with AI to catch billing errors before they get paid out. Just raised $55M in our Series B led by Transformational Capital.

We're hiring a Principal Engineer, backend-heavy role (85-90% backend), to own architecture across multiple teams and help set technical direction as we scale.

Stack: TypeScript, Node.js, GraphQL, PostgreSQL, AWS, React/Next on the frontend.

You'd be:

Owning delivery on systems spanning multiple teams Driving adoption of AI coding tools (we use Claude Code) with real usage across the team, not just experimentation Mentoring senior engineers, influencing technical decisions without needing to go the management track Working closely with product and business leadership on technical strategy

Looking for 15+ years of experience, real hands-on TypeScript backend depth (Node.js, NestJS, or similar), and ideally some exposure to healthcare, fintech, or another regulated-data environment, though that's a plus, not a hard requirement.

Hybrid, 4 days/week in our SoHo office.

Please apply on the site:https://careers.kula.ai/alaffia/34483c

We recently raised a $54M Series B led by Accel with participation from Kleiner Perkins, Felicis, Altos Ventures, and YC.

Permitting is a challenging yet interesting problem; thousands of municipalities across the United States have their own processes and requirements - many which are continually updating. Software, AI, and LLMs provide an exciting opportunity for us to reason at scale and distill a nuanced and localized permitting process into a standard and streamlined experience for our customers.

We're looking for customer-obsessed, ambitious, and hard-working teammates who are excited about solving a real-world problem with technology at its helm.

We're rewriting resortpass.com — starting with our highest-traffic surfaces (SRP/DLP) — and need a Senior Frontend Engineer to be the technical anchor. ~75% of pages get touched this year: international expansion (Mexico & Caribbean now, Europe next), in-housing search from Algolia, a new Hotel SaaS tool, and Spa as a major new vertical.

Senior role, Staff-leaning scope, clear path to Tech Lead. 2/3 of traffic is web, so performance is business-critical (Core Web Vitals, SEO, caching), and this codebase is also our launchpad for AI features (concierge chatbot, AI spa booker).

Stack: Next.js 16 (App Router), React 19, TypeScript, Tailwind, shadcn/ui. Backend: Rails, Node/AWS, Postgres, MongoDB. Playwright + Datadog.

You'll own: technical design (RFCs) for major rewrites, reusable App Router patterns, code quality/mentorship for a junior-leaning team, and API contracts with backend.

Need: 6+ yrs production web apps, deep React/Next.js expertise, proven track record leading high-traffic rewrites with measurable results. Strong full-stack engineers open to leveling up on React also welcome.

Visa: not standard, possible exception for exceptional candidates. JD + Apply: https://uctalent.io/referral/Huynh_Nhu_Bao_Nhan221138/v8QmsN...

Dablam is an AI-native reputation intelligence firm. We help corporations shape how they're understood in an information environment increasingly mediated by LLMs—surfacing information that's true and under-represented and getting it to the right audiences at the right time.

We expand our team with multiple BDR roles in London and NYC. We're looking for 3+ years of BDR/SDR or comparable B2B outbound experience, AI automation, Clay, strong cold-calling and written outreach skills, CRM experience (HubSpot/Salesforce), and a genuine interest in AI and reputation. Comp: competitive base + uncapped commission + equity, plus medical/dental/vision, 401(k) match, generous PTO, professional development budget.

Apply by sending your CV to careers@ our website. Only natural persons with the right work permits, no recruiters, AI agencies or companies. Expect fast replies.

Deep learning transformed text and images but mostly skipped tables - the data behind most clinical trials, financial models, and scientific experiments. The reason is structural: no natural sequence, no spatial structure, no shared vocabulary across datasets, so the architectures and scaling laws behind LLMs don't transfer.

Our approach: pre-train a transformer on millions of synthetic datasets sampled from causal-structure priors. Your whole dataset goes in as context, predictions come out in a single forward pass - no per-dataset training, no hyperparameter tuning, seconds instead of hours. It works: TabPFN v2 was published in Nature and set a new state of the art; TabPFN-3 scales to 10M rows. 4M+ downloads, 8k+ GitHub stars, production use from liquid biopsy to rail maintenance. As of last month we're an independent lab inside SAP, backed by €1B+ - models stay open, research stays public, same team and offices.

Open roles (most can sit in any of our three offices):

Senior ML Infrastructure Engineer - own multi-cluster GPU infra (Slurm on GCP today, multi-provider next), training performance, and the tooling layer. We spend tens of millions/year on compute; you own that budget.

Research Scientist, Foundation Model - drive the model agenda: novel architectures, scaling 10K to 1M+ samples, multimodal and causal directions. PhD + top-venue publications or equivalent.

Research Engineer, Foundation Model - same agenda from the engineering side: you design experiments, write the training and eval infra, and co-author the papers.

ML Engineer, Cloud Platform - design and scale the backend that serves and finetunes the models. Python/FastAPI, Terraform, K8s.

Full Stack Engineer, ML Platform - build the product end to end. TS + Python, React/FastAPI/Postgres.

Also hiring: Applied Scientist, Forward Deployed ML Engineer, Research Scientist (Foundational Data Science), PhD research interns, plus GTM and ops roles.

~40-person team with backgrounds from Google, DeepMind, Jane Street, Goldman, G-Research, CERN. Led by Frank Hutter, advised by Bernhard Schölkopf and Yann LeCun. Comp competitive with top AI labs.

We’re looking for a senior, hands-on engineer to tackle:

- Core agent, product, and infrastructure systems

- Context, memory, orchestration, and tool use

- Simulation environments for users, schedules, relationships, and multi-agent interactions

- Evaluations for long-horizon agent behavior, reliability, and safety

We care a lot about high agency, collaboration, and high ownership mentality. Strong product judgment and care for user experience matter as much as technical rigor.

For example, our engineering team in India works primarily from our Gurugram office.

We’re a small, high-impact team solving one of the most interesting and adversarial problems in fintech: how do you build systems that reliably determine whether a real human is on the other side of a financial transaction? We’re hiring across Engineering (Full-stack and Infra) and Data Science / ML roles. Hiring at Manager/Director level as well as mid-level/Senior levels. We’re language-agnostic and hire for fundamentals.

Across the team you’ll see: • Python, Go, Rust, Scala • PostgreSQL, Snowflake • Kafka, Redis • Terraform, Kubernetes • ML: XGBoost, PyTorch, Feature stores, real-time scoring pipelines

If you love solving complex distributed systems challenges, building customer-facing ML products, or working on detection systems that must be both high-precision and low-latency, you’ll fit right in.
