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.
Tech Stack: [TypeScript, React, Node.js, Rust]
-- SENIOR PLATFORM ENGINEER -- Build and maintain user-facing platform features, write TypeScript/Node backend services and React frontend components, and more. Requirements: experienced in shipping production full-stack web apps, integrating and maintaining 3rd party APIs, debugging, cloud hosting [...]
-- SENIOR PRODUCT ENGINEER, FRONT END -- Define and evolve the frontend architecture of a large-scale, real-time browser-based engineering tool, and more. Requirements: React/TypeScript, shipping and iterating on complex interactive web applications, passion for UX [...]

Dynasty helps startup founders legally eliminate millions in capital gains taxes through QSBS trust planning. Today, sophisticated tax strategies are locked behind elite law firms and opaque processes. We’re building the software layer that makes advanced trust and tax infrastructure accessible, understandable, and fast.
We combine fintech, legal infrastructure, and thoughtful product design to turn what used to be months of paperwork and six-figure legal bills into a streamlined, guided platform. Our customers are venture-backed founders preparing for exits when the stakes are high and precision matters.
We’re early, fast-moving, and product-obsessed. This is a chance to help define the system of record for founder wealth.
Positions:
* Engineering: Hiring an experienced python / react engineer to help build the next generation of financial platforms. -> kyle@getdynasty.com
* Sales: We need to hire our second sales rep ASAP -> alessandro@getdynasty.com

Oboe's goal is simple: teach one billion people one trillion things. We'll do that by building the world's first completely generalized AI-powered learning platform. Today, so much of our focus is spent on making machines smarter. We believe it's time for machines to make humans smarter.
We're looking for a Full-Stack Engineer to work across Oboe's stack, from our backend pipelines that leverage AI to generate world-class content, all the way to the interfaces that our users engage with on the web.
We're a team of generalists, so this job will have you learning every part of the systems and features that bring Oboe to life. This is a highly hands-on role where you'll have tremendous impact, ship real features to real users, iterate quickly, and learn a ton.
Tech Stack: Node, TypeScript, React, AWS, MySQL, LLMs.

BillionToOne builds molecular diagnostics that detect disease at the single-molecule level. Our prenatal test is the only non-invasive screen for both recessive conditions and aneuploidies from one blood draw. Our oncology platform finds 50%+ more cancer treatment options than standard testing. Over 1 million tests processed to date. Every line of code here has a patient on the other end of it.
Revenue grew from $0 to ~$300M in four years, guiding $415-430M for 2026. Publicly traded and GAAP profitable. You'll work alongside clinicians and computational biologists on genuinely hard problems: scaling genomic pipelines, building digital infrastructure for complex test results, and shipping systems where correctness isn't optional.
Hiring across software engineering:
- Senior Software Engineer, Digital Experiences (Oncology and Prenatal)
- Senior Software Engineer, Oncology
- Senior Software Engineer, Prenatal
- Senior AI Engineer
Stack: Python, Django, Postgres, React, TypeScript, AWS, Docker, Terraform, Kafka, CircleCI, Datadog. AI-assisted dev tools (Cursor, Copilot, Claude Code).
Benefits: Access to the latest AI tools and models with unlimited usage to help you do your best work, 100% paid medical on select plans, 16 weeks fully paid parental leave, 401(k) with 4% match, daily catered lunch, on-site gym. Forbes Best Startup Employers 2024 & 2025.
Chestnut builds the systems insurance carriers actually run their distribution business on. We replace spreadsheets, legacy vendor systems, and manual processes with real-time data, deterministic workflows, and AI-assisted tooling.
This is end-to-end product engineering.
You won’t just write APIs. You’ll design schemas, build backend logic, ship UI, deploy to production, and handle the sharp edges that show up with real customers. The problems are messy and state-heavy: payouts that must reconcile with finance, onboarding flows with regulatory constraints, dynamic hierarchies, retries, chargebacks, partial failures.
We care a lot about correctness. These systems move real money and cannot drift.
Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS
We use AI heavily in our workflow — for drafting, refactoring, test generation, and exploring solutions. We expect engineers to use it aggressively. We also expect you to understand what it’s doing, spot when it’s wrong, and maintain strong fundamentals. Taste matters.
You’ll likely thrive here if you: - Have 3–6 years building real product systems - Are strong in at least one typed language and comfortable picking up others - Enjoy owning features end-to-end - Think in terms of invariants, edge cases, and failure modes - Like shipping quickly but cleanly - Want to build systems that operate in production, not demos
We’re a small, high-agency team. You’ll have meaningful ownership and direct impact on customers.
Hybrid in SF and Seattle.

We're the team making Copilot indispensable. Building AI features inside Word, Excel, Teams, Outlook, and the Copilot app that users actually reach for every day.
You'll own capabilities end to end, run experiments that move the dial, and collaborate with designers + PMs to ship fast. The tech stack adapts to the problem. The impact? Measured in millions of users and their productivity gains.
We obsess over one thing: getting users to that "wow" moment as fast as possible. If you like shipping, learning, and seeing your code change how people work, this is it.

Strobe is building the world's largest power plant — not a single site, but a distributed fleet of buildings, batteries, EVs, and generators buying and selling power in real time across wholesale energy markets.
We need a senior engineer to own our data integration and cloud infrastructure layer — the connective tissue between utilities, grid operators, OEM hardware, weather services, and our optimization engine.
What you'd own:
– Wholesale market integrations (NYISO, CAISO, ERCOT) — real-time pricing, capacity markets, demand response signals
– OEM hardware integrations — API and data bridges to building equipment manufacturers for monitoring, control, and telemetry
– Green Button Connect pipelines — ingesting interval consumption, billing, and meter data from utilities (ConEd, PG&E, SCE, etc.) via OAuth2 + ESPI
– Weather and solar forecast data pipelines
– Utility bill reproduction engine — modeling site economics before and after Strobe to forecast financial impact across dozens of rate structures. This simulation infrastructure is core to how we sell and deliver value.
– Event-driven AWS infrastructure (Lambda, API Gateway, AppSync/GraphQL, EventBridge, IoT Core, TimeStream, Amplify, CloudWatch)
– Terraform IaC — real module design, remote state, multi-workspace patterns
– Observability and alerting on systems where downtime means missed market events and real dollars
Strong fit if you have:
– Deep AWS experience (IAM, Lambda, API Gateway, AppSync, EventBridge, TimeStream or similar TSDB)
– Production Terraform (modules, remote state, multi-workspace patterns)
– Extensive Python (pydantic for models, click for CLIs, boto3 for AWS, async pipelines)
– Experience integrating messy third-party APIs at scale (utilities, government, energy, OEMs)
– Comfort with on-call for systems that control physical hardware and move real money
Stack: Python / TypeScript / Rust / Terraform / AWS / GraphQL (AppSync) / MQTT / Grafana — AI-agent-optimized monorepo with deep investment in agent-enabled engineering efficiency.
Small team, high ownership, no layers. 5 days/week onsite at Newlab, Brooklyn Navy Yard.
