Lead Full-Stack SW Engineer

vor 1 Woche

Winterthur, Zürich, Schweiz Circleup Vollzeit

We welcome highly experienced candidates preferred from a +/- CET time zone.

At Circleup, we're connecting people in person - offline - by simplifying the process of scheduling a meet-up and booking a place at your favorite restaurant in your city within a few seconds.

Minimum effort spent on scheduling, choosing a time, and deciding on a place to meet.

Circleup enhances the efficiency of maintaining your relationships and professional network. Unlike individually having to think about whom to meet again and doing the inefficient communication ping-pong to figure out when and where to meet, Circleup automates to reduce manual work.

You will save time, reduce your mental workload, and get more quality time with people you know and like. As a result, you will be better connected and happier.

__

At this point, we are self-funded and at a pre-product-market-fit stage.

You'll lead the development effort which means you also take technical decisions. You'll have a part-time team (all functions) available and you'll make sure each team member's capacity is utilized optimally. It's all about getting most out of the resources available.

Joining Circleup as a Lead Engineer presents a unique opportunity to contribute from the very beginning and play a pivotal role in shaping both the product and the organization.

As one of the earliest team members, you will have significant equity ownership, influence over key decisions, and the chance to help recruit and mentor other engineers as we scale. This position offers a high degree of autonomy and self-agency, empowering you to make impactful contributions across the entire product and technical stack.

We encourage a deep understanding of our software architecture and business logic, enabling you to make informed decisions and valuable contributions across the entire product ecosystem.

You will directly shape the trajectory of the company, witnessing and influencing its growth from the ground up. If you value the opportunity to take ownership, innovate, and be part of building something meaningful with long-term rewards, Circleup provides an exceptional environment to realize that potential.

Therefore, we make an effort to not limit the scope of one person's work. You will be encouraged to bring up your own ideas on new features, and treat them like a science experiment with users: observation -> research -> hypothesis -> experiment design -> experimentation -> data analysis -> conclusion interpretation -> communication -> refinement.

Key values that are important to us:

Trust - We have an open-door policy, which means we encourage team members to talk about problems they see

Accountability - we expect people joining to take ownership of their role and potentially beyond to drive success. We expect transparency about mistakes that happen or are made and avoid excuses so that we can all help to get solutions faster together.

Responsibility - as a company, we have a responsibility to act in good faith towards users, customers, investors, and potentially other stakeholders. We expect team members to act responsibly.

Integrity - building a company requires the highest levels of integrity from each team member.
