Reio | Backend engineer/UI/UX Designer | UK | Remote or Onsite | reiohr.com

Reio lets businesses manage employees, payroll, and create efficient shift combinations.

Django/Python, Postgres, AWS, React. We are 5 people, so everyone gets to do pretty much everything. All of us code (to varying degrees). One requirement, as well as CS ability, everyone has to be in the UK, if remote, as we do meet in the office occasionally and it is better for time zones, team building, given the size of the company.

Causal | Full-stack Engineer | London (UK) or REMOTE | https://causal.app Causal is a human way to think and communicate with numbers. Our product is a number-crunching tool that's a bit like a spreadsheet and a bit like programming. Our vision is to be the de-facto way for anyone to work with numbers on a computer.

We're very early stage, but well-funded by some great investors across the US and Europe, and ready to make our first hire.

---

Role: Full-stack Engineer

* Our stack is React/Redux/TypeScript on the frontend, and Node/TypeScript on the backend. We're looking for engineers who have experience with these technologies.

* Our product primarily consists of a web UI on the frontend and a computation engine on the backend. The product needs a low floor and a high ceiling — it should be simple enough for anyone to get started with, but powerful enough for really complex use-cases. Performance is paramount on both the frontend and backend.

* Our next big project is a rewrite of the computation engine to efficiently handle models with up to 1M nodes. The challenge is to show the user instant results (frontend) when possible and run complex operations (Monte-Carlo simulations, API calls) on the backend. We also want to improve our multi dimensional modelling capabilities which leads to various UI/UX challenges.

* Our roadmap contains more projects we're planning to work on: https://www.notion.so/00f79272b4ec4d6790ec98120788d850.

We have a nice office in London (UK) but are also open to remote hires. If this sounds interesting then I'd love to chat! Email is hidden

Sompani | Software Engineers | Berlin, Germany or REMOTE | https://www.sompani.com

We're hiring Software Engineers to join us in Berlin, Germany, or remote, to help us grow our software with a holistic approach: Back-end, front-end, server infrastructure, testing and continuous delivery pipelines.

Please don't hesitate to write us, we're looking for kind people from different backgrounds and identities to bring in a fresh perspective. We're commited to continue building an inclusive place for you to grow professionally with us. We're a small, friendly group of multicultural (CH, DE, RU, ES, US) startup veterans.

--- ABOUT THE JOB

Our SaaS is used by VCs (Venture Capital firms) and their portfolio companies. They love our products because they help find talent for the companies in which the VCs invest.

Our SaaS architecture is written in strongly typed, modern PHP 7.4, using the Symfony framework. In our CI/CD pipeline, we use, and we contribute to PHPStan and Psalm because they help us write reliable, solid code.

We have another product written in Clojure, because we believe that learning other programming paradigms helps us to grow as developers, independent of the language used.

We love working with PostgreSQL and expose public and private APIs directly through PostgREST because we strongly believe that a server request should be handled within 100-200ms max. Help us optimize queries and learn about EXPLAIN ANALYZE execution plans with us.

We are strong believers in Server Side Rendering, with AJAX requests done by little helpers like Intercooler (now htmx.org) or Turbolinks, added for an interactive Look&Feel.

We help VCs aggregate the jobs postings of their portfolio companies. To make this work, we constalntly have to expand our knowledge about CSS and XPath selectors, web crawling techniques, and headless browser instrumentalization via WebDriver and tools like Selenium.

Our CI/CD pipeline runs on GitLab and deploys our SaaS products after running tests and making sure that no regressions will happen. We run Trunk Based Development in a truly agile fashion: We take the "Kaizen" principle seriously. No heavy-weight processes our hour-long meetings. Promise.

We run rented Linux servers and are experimenting with *BSD because while we run parts of our infrastructure on the AWS and Google Cloud, we understand the tradeoffs of cloud offerings and learned how to operate our own Nginx servers, caches, load balancers, and monitoring tools. Doing all that helps us assess much better when to "roll your own", and when to buy a ready solution. After all, we are engineers and like to tinker, but at the same time we're enterpreneurs, and know when to prioritize.

--- ABOUT YOU

If you feel at home with PHP or Clojure, PostgreSQL and Linux, and maybe even some more of the above technologies, let's talk.
