IP Copilot | Software Engineer - Integrations (Python/Ruby) | Full-Time | Remote (US) | US Citizen | https://ipcopilot.ai

IP Copilot is an AI platform that discovers patentable innovations in real time and streamlines the patent process for enterprises, universities, and law firms. Fresh off a September 2024 seed round, our nine-person, fully-remote team (ex-researchers with 1,000+ patents and multiple enterprise launches) is hiring a back-end engineer to own integrations into our Python/Ruby API and third-party services, harden our AWS/PostgreSQL infrastructure, and ship features that automate patent workflows. You’ll collaborate with ML, design, and business teammates, meet power users, set the roadmap, and build thoroughly tested, monitored services—all while wearing the many hats that come with an early-stage startup.

Perks: excellent health/dental/mental-health coverage, equity, competitive salary, unlimited vacation, mentorship, and real ownership.

P-1 AI | Hybrid (SF) and Remote (US) roles | Full time

P-1 is trying to do for physical engineering (mechanical, aerospace, electrical), what Devin, Cursor et al. are doing for the software world. Founded by ex Airbus execs and DARPA program managers, we've just raised a $23 million seed round. Our goal is to solve engineering AGI to enable humans to scale engineering complexity by orders of magnitude.

We have several roles open including:

* Research Scientist - Applied AI

Looking for creative people to innovate on agentic AI systems for specialized engineering domains.

* ML Engineer - Training and AI Infra (ad should post tomorrow)

We're doing a lot of LLM fine-tuning and reinforcement learning. We need someone who can make our GPU cluster sing!

* Software Engineer - AI Evals and Test

We believe it's essential develop rigorous, domain-specific evaluations in order to ensure we're making progress on real world issues -- not just hill-climbing on general purpose benchmarks.

... and more!

Around | Lead Backend Developer | Full-time | Remote

We’re building a modern platform to transform how companies in the consumer packaged goods (CPG) industry operate and grow. Our goal is to streamline the way products are presented, shared, and sold across global markets. We’re post-MVP and pre-revenue, now moving fast to onboard early users and shape the future of this industry.

We’re looking for a Lead Backend Developer to join our ambitious, early-stage startup as a foundational team member. If you’re excited by the idea of taking the lead on the ongoing development and strategy for our backend architecture, making high-level technical decisions, and getting in at the ground floor of something big — we want to talk.

AI x Healthcare Startup | 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 several top tier VCs. We're on a mission to ensure patients get the coverage they deserve from their health insurance.

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. We have a 6+ month customer waitlist and growing insanely fast.

We're hiring our first engineer outside the founders. You'll work directly with customers to understand their needs, design the right solution, and build from zero to one. You'll own entire parts of the roadmap and tech stack while wearing multiple hats. Most important characteristics are resilience, work ethic, and curiosity. We care about slope, not where you are today.

This is an opportunity to work in an insanely 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!

RWX | Software Engineer | REMOTE (US) | Full-time | https://rwx.com

$175K – $250K + equity

We're a CI/CD platform with an entirely differentiated execution model. Rather than parallelizing jobs on VMs, we provide a serverless interface using a graph of tasks. We then have automatic, content-based caching, which eliminates the large amount of redundant executions that CI platforms have today. You can test changes from a local CLI so that you don't have to commit and push to run. We've made substantial improvements to every aspect of the developer experience.

We're looking for backend-focused engineers who excel at building developer tools. Our engineers are effectively product managers as well and work highly autonomously.

We're building the world's first observability stack for mission-critical hardware sensor data. Founded by engineers who've literally put rockets into orbit, Sift provides unified data pipelines, infrastructure, and analysis tools for complex hardware systems.

Our platform helps aerospace, robotics, and other hardware companies accelerate their engineering cycles by turning "trial and error" into "trial and measure." We work with companies like Reliable Robotics and others pushing the boundaries of autonomous systems and space technology. We're looking for engineers who are passionate about:

- Building scalable data infrastructure for real-time telemetry

- Working with mission-critical systems where failure isn't an option

- Helping the next generation of machines reach orbit and beyond

If you're interested in joining a team that's making hardware development faster, safer, and more data-driven, apply above!
