⚙️ How we work
Rhythm: Lean Software Development We work in very short cycles, where work takes as long as it takes, but we try to simplify every iteration, release early, test and learn.
Asynchronous (focus days) + synchronous (office days) You should collaborate as though most things you ask of others will get an answer eventually, but not necessarily right this second. Your first choice of action should be to post a message, a todo, or a document about what you need to explain or need to know. Then others can read it on their schedule, when the natural lulls of the day allow it, rather than being interrupted right in their peak flow time
- Focus and quality time to work
- Synchronous meetings: there will be times when you do need to tightly collaborate with someone in real time, but those cases should be infrequent. We have pings, video calls, screen-sharing, or even in-person collaboration for when async isn’t efficient.
Ownership and proactivity: managers of one Setting your own direction when one isn’t detailed; determining what needs to be done, and doing it, without waiting for someone to tell you to.
Communication Since we work asynchronously and remotely, it’s important to radiate information about what we’re working on. We use slack channels profusely.
Work-life balance We believe in the value of a balanced life, which is why we maintain a 40-hour work week. Keeping working hours reasonable helps us focus on what truly matters and ensures that our time and energy are spent effectively. Rest, good sleep, and a fulfilling life outside of work are essential for long-term success and well-being.
Occasionally, off-hours work may be required for on-call duties, maintenance, or emergencies. However, these instances should not extend your total working hours. We trust you to take the necessary time off to recover and balance any extra efforts during the week.
👥 The team
We are a small, hands-on team with deep experience building and scaling software solutions. At Ecostars, we combine product, engineering, and sustainability expertise to design practical tools for the hospitality industry, focusing on turning complex ESG and operational data into clear, actionable insights.
