Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. At Trunk, our mission is to help teams create high-quality software quickly. We've helped engineerings teams at: Google X, Zillow, and Brex to understand why their builds fail, which tests are flaky, and how to ship code faster without sacrificing reliability. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!

Marker is a technology venture from 3 leading communications agencies. We’re an incubator building and launching force-multiplying software products for communications teams.
Our first product is Delve (https://delve.news) — a coverage monitoring, analysis, and insight toolkit to track and measure the entire online conversation about your business or industry.
Our product team is small and autonomous, but with the resources, expertise, and customer access of the global agencies we work with. We’re hiring an early engineer to join us on this journey; you’ll have a large impact on what we build, how we build it, and where we’re going next.
Our current technology stack includes Deno, React, and PostgreSQL. Bonus points for expertise in any of: data visualization, distributed systems, web scraping, large-scale data pipelines.

Pango is building the world's first Agentic Operating System for e-commerce logistics. Our vision is to create the AI e-commerce employee of the future. We are forming our core team in Stockholm and are looking for exceptional engineers. We are based at the SSE Business Lab, where companies such as Klarna, Voi, Budbee or Legora originated. We have achieved a product-market fit and are growing rapidly.
You are a good fit if:
* You are comfortable maintaining, expanding and operating an entire B2B SaaS platform with a high sense of ownership.
* You are happy to take on work that in a large company is divided into a dozen roles, and execute it all at a good enough level.
* You are unafraid of any technology. If we need a desktop app and you haven't done one before, you will study the documentation of Electron.js and build one. If a model for predicting delivery times is needed, you will do a literature review to find the right architecture and train one.
* You have strong proficiency in any backend language or platform, with a strong willingness to dive deep into PHP/Laravel OR strong proficiency in JS/React.
* E-commerce (Shopify, Magento, other platforms, shipping carrier integrations) experience is a plus.
You will take a key role in shaping the product and company, with ability to make an impact and advance career limited only by your aptitude and interest.
