Upwave | Senior Software Engineer | REMOTE (US) | https://upwave.com
Upwave is a YC/venture-funded startup that helps large enterprises plan, measure, and optimize brand advertising campaigns using advanced analytics and AI. We offer a comprehensive set of tools that help our Fortune 500 clients understand and improve how they're perceived in the marketplace, how aware consumers are of the value they provide, and how much consumers trust them to provide the value they promise.
Our platform leverages AI to deliver deeper insights, automate complex analysis, and help marketers make data-driven decisions faster. We've been rapidly expanding our list of enterprise customers and deepening our integrations with "household name" partners. As we grow, we need engineers to help us build even more unique, differentiated, valuable, scalable, and robust analytical SaaS tools and products.
About the Role: Upwave is a startup and we need an experienced generalist "startup engineer" who's experienced doing the wide variety of technical work that modern SaaS startups need. That includes backend web development (JVM frameworks), frontend SPA development (mostly React), AWS-based cloud engineering, data engineering, and working with AI/ML capabilities to enhance our analytics platform.
Our team emphasizes high-quality, high-velocity, sustainable software development in a collaborative and inclusive team environment. We're a small team that gives our engineers a lot of autonomy, and we want people who are excited to step in and learn whatever's needed to get the job done (whether that's new technical skills or business domain knowledge.)

Comper | First Product Designer / UI Engineer | €80-100k + equity | Utrecht, The Netherlands | ONSITE | https://comper.io
We make software landscapes understandable and explorable. Our canvas is zoom-to-code shows data on overlays from all of the git repos in your company. LLMs go through the codebase and extract information.
We provide clarity when it's most needed: re-orgs, onboarding, explaining the tech stack at board meetings.
Comper needs someone that can design revolutionary UIs and go where no man has gone before. I don't know exactly what to call this role, as it crosses several disciplines: Design, Engineering, new UIs. Our UI is the core of our product: a zoomable canvas that has all your code, documentation and diagrams on it. We have a long way ahead and need serious thinking to make sure we explain the software stack as simple as can be.
Site is a bit outdated as it's not prio #1. Happy to chat. I'm the founder & CTO. We just raised a pre-seed.

Root Sustainability | Senior UX/UI Designer | REMOTE/The Netherlands (or hybrid) | Full-time | Seed-stage + equity
We’re Root Sustainability, helping retail brands to turn scattered, incomplete operational data into auditable, high-granularity sustainability insights, and we’re doing it from the bottom up. Think tens of millions of data points, messy ERP exports, complex supply chains, and sustainability logic that most tools can’t handle. Our goal is to make all of that feel simple, clear, and usable for the people who rely on it every day.
Role:
You’ll own UX/UI end-to-end: research, flows, wireframes, prototypes, and polished interfaces that make complicated domains feel obvious. You care about usability, accessibility, and simplicity in the face of ambiguity. You work closely with product and engineering, not as a service, but as a partner shaping what we build next.
What you’ll do:
Lead design for key features: mapping, dashboards, workflows.
Turn fuzzy sustainability domain problems into clear, user-centered interfaces.
Build prototypes and run lightweight user testing to validate assumptions.
Maintain and evolve a design system (Figma, etc.).
Collaborate closely with engineers, you’ll be shipping frequently, not just handing off specs.
You should apply if:
You have ~5+ yrs experience in UX/UI with a strong portfolio.
You’re pragmatic: prioritize clarity over trends, iteration over perfection.
You thrive in early-stage environments where priorities shift quickly.
You know design systems, user research, and can defend your decisions.
Bonus: data viz experience, sustainability passion, accessibility chops.
Perks:
€60,000 – €70,000 gross per year with stock options.
Remote-friendly / hybrid with occasional meetups.
Direct impact, your work shapes product direction.
Flat culture; work with a small, mission-driven team.

Now you need the right people to notice, consistently.
And of course, you want it to be automated, but not sound robotic.
That’s where I come in. I work at the intersection of positioning, copy, email, and systems -- turning a good product into attention and a steady pipeline.
GTM engineering + B2B lead gen + copywriting + emails.
Open to full-time, part-time or fractional roles with smart teams that need help in this area.

Legion Health (YC S21) | Founding Engineer (AI-Native Ops Infra) | San Francisco | ONSITE | VISA SPONSORSHIP | $130k–$190k + Equity
Legion Health is building the AI-native operations layer for mental health care. We run our own psychiatric practice and use AI agents to handle the complex "backend" of healthcare—scheduling, intake, documentation, billing, and risk detection. We have $3M+ ARR, $7M+ raised, and our infrastructure currently supports 2,000+ patients with only one human support lead.
We're hiring a Founding Engineer to own our backend and agent systems end-to-end. This is not a "wrapper" role; you will be architecting the state machines and event streams that turn clinical intent into reliable operations.
The Role:
Build AI Co-workers: Implement agents with tool use, memory, and safety rails that act as trustworthy teammates for clinicians.
Event-Driven Architecture: Design the schemas and workflows (Node.js/TypeScript/Postgres) that encode how psychiatric care operates.
High Impact: Your work lands in real clinical workflows immediately, directly improving patient access and care quality.
Tech Stack: Node.js, TypeScript, Supabase (Postgres), AWS (ECS/Lambda), Next.js 15, OpenAI/Anthropic.
Offer:
Comp: $130k–$190k base + significant early equity (0.2%–0.8%).
Location: San Francisco (In-person).
Process: Intro -> Systems Deep Dive -> Practical Work Trial (No Leetcode) -> Onsite. We move fast (7-10 days).
Email me at yash@legion.health if you have questions or if you're super cracked and I have to know about you.

Gambit Robotics | Founding Principal / Staff Full-Stack Engineer | NYC | Onsite | Full-time
Hi! I’m Nicole (ex-Google AI), cofounder of Gambit Robotics with Eliot Horowitz (cofounder/CTO MongoDB).
We’re hiring for two founding engineering roles to work directly with us in our NYC office (in-person only):
1) Founding Principal / Staff Full-Stack Engineer - 8+ years experience shipping production systems - Strong backend and systems foundation - Experience owning architecture end-to-end (zero → production)
2) Founding Full-Stack Engineer - 4–6 years experience building and shipping production products - Strong product sense and ownership - Comfortable working across backend, client, and infrastructure
https://www.gambitrobotics.ai/careers
Gambit is an AI-powered kitchen assistant that mounts magnetically under most range hoods or microwaves. It uses computer vision, thermal imaging, and on-device AI to understand what’s happening in the pan in real time, and handles the hardest parts of cooking — heat, timing, and doneness — so people get better results with less stress.
We’re moving quickly from prototype to product and launching via Kickstarter later this month. It’s a seed-stage startup with high autonomy, real impact, and a very intense (and fun) next phase.
If you or someone you know might be a fit, email me: nicole@gambitrobotics.com
