Cliniko is practice management software that makes life easy for allied health professionals by handling appointment scheduling, storing treatment notes, managing invoices and payments, running video consultations, and much more. The software is used globally by 100,000+ people every day.
It’s a web application built using Ruby on Rails in the back end and we’re in the process of transitioning the front end to React.
Cliniko is made up of a team of 63 considerate and friendly people, spread around the world. We work completely remotely, although our base is in Melbourne, Australia. We care much more about finding the best person for the job, rather than looking for someone that lives nearby.
We don't have managers, we don't have meetings, there are no time-sheets to complete. We're responsible, autonomous, creative, and proactive in doing our best for our customers.
We're focused on making great software and providing great support. We take pride in doing our best work, and enjoy bettering ourselves and each other. We strive to make the world a bit better, both personally and through our work.

I’m Scott - founder of DoStuff. We have a pretty big, and growing, membership product called DoMORE - $7/month for a pair of tickets to an event we think you’ll like. We’re hiring a hands-on Retention Product Engineer to own engagement → churn reduction end-to-end.
You will analyze cohorts, define the retention north-star metric, ship product and lifecycle experiments yourself, and measure impact.
This is not a PM-only role and not a pure engineering role. You own the full loop: insight → build → measure → iterate.
Our stack: React (FE), Ruby on Rails + Elixir (BE), Postgres, Elasticsearch. Proprietary lifecycle tooling for email, SMS, and in-app (web). No feature-flagging or experimentation framework yet - you’ll help install the remaining plumbing.
Retention is the highest-impact opportunity in the business and this role has real authority to ship.
If you have experience with the above and this sounds like fun, reach out to scott+domore@dostuffmedia.com with something in the subject line that let’s me know you’re real and interested. THX

Return (https://return.energy) is hiring a software engineer to work on platforms that accelerate the transition to carbon-free energy. Return’s main activity is building and operating industrial-scale Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will make a measurable, country-level impact on the transition to renewable energy. Return recently raised €300M to support its growth.
While we employ more than 120 people, Return’s technical team remains small with 13 members. Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service.
During the first three years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced software engineer.
Your primary focus will be to further develop our battery virtualization platform, enabling customers to use slices of battery capacity distributed across our fleet of industrial-scale batteries.
Our tech stack and toolset are straightforward: Go, Python, Ruby, PostgreSQL, TigerData, dbt, Dagster, Grafana, Terraform, and self-hosted plus cloud compute. We keep meetings to a minimum to provide at least five hours of uninterrupted coding time per day. We conduct code reviews and apply both automated and manual testing. Our web apps and platforms are often deployed multiple times per day.
Return has offices in Amsterdam, Berlin, Brussels, Hamburg, Munich, Madrid, and Stuttgart. We are very open to remote work as long as you live in the EU. Our hiring process is swift but thorough: a brief call to get acquainted and discuss finances, followed by one or more technical interviews, and a paid visit to Amsterdam to meet the team.
The tech team members have co-founded several companies and have worked with remote development teams since 2008, and they will personally guide you through most of the recruiting process (there is no recruiter involved).
We aim to hire you in February or March ultimately.
