Job description

Looking for someone to join us as one of the early members of the Backend team. In the initial months, you'll be working closely with the team, gradually taking ownership of central components and features. Given our early stage, we're seeking versatile engineers, comfortable contributing to various aspects of the company's foundation.

We value team members who delve deep into their respective domains, aiming to cultivate a team of subject matter experts. This commitment to expertise is an expectation of every team member.

The backend team at amo is responsible for both server side and the backbone of the client as we believe it makes more sense to have one team handle both ends of the same topics (network, data modelling, management and synchronisation, etc).

Crafting the Future

Developing systems that handle massive traffic, data, and an unmatched rate of scaling. Your toolkit? Carefully chosen cutting-edge technologies, code that's practically poetry, and systems that effortlessly scale horizontally.

Cross-Platform Harmony

In addition to server side development, you will participate in the evolution and maintenance of a Rust component that we share between iOS and Android and that deals mostly with networking, data synchronisation and data-oriented feature logic that benefit from being written just once. You will collaborate with iOS and Android engineers to maintain a unified codebase, enabling consistent experiences across platforms. You'll also bridge the gap between mobile development and backend infrastructure for a seamless user journey.

Feature Development

Participating in brainstorming sessions and discussions to design and implement features that set us apart in the market.

Continuous Improvement

We love learning from each other, staying abreast of industry trends and emerging technologies, bringing fresh ideas to the table. So you'll be contributing to our culture of continuous improvement, where learning and growing are integral parts of the journey.

Owning your scope

You will be responsible for monitoring analytics and managing system crashes. We value engineers who take ownership of their scope, and proactively address issues and triage bug fixes.

Your Skills & Experience

We are hiring multiple engineers of varying levels, so please indicate your years of experience on the application form to apply for the appropriate position.

• Experience writing Rust (either open-source or professional work) or any other low-level systems programming language (C++, C, OCaml, ...).
• Experience working with distributed systems in production (like Redpanda/Kafka or/and ScyllaDB/Cassandra, etc.).
• Strong opinions about building a product in the consumer social domain is preferred.
• You don't need to speak French to apply (and you don't need to speak perfect English either, we'll help you to ramp up quickly if needed).
• Vacation days: 8-9 weeks (total) per year - (European summer? ).
• 5 weeks of paid time off (by the state);
• 1-2 additional weeks (RTT, based on our company contract);
• ~11 bank holidays. We shut down entirely twice a year, two weeks in summer and one week in winter to allow everyone to truly recharge and to avoid prolonged slowdowns (especially in the summer). These pauses are part of your total vacation time, giving everyone a real chance to unplug and recharge. No Slack, no email, no FOMO.

Life at amo

To ensure that everyone is set up for success within our way of working, we work together onsite 5 days a week.

We wanted to make sure coming to the office was as comfortable as possible for you:

• We chose a location in central Paris, near Opera (Metro lines 3,8,9 and RER A).
• We have a beautiful Parisian-style office with high ceilings, balconies, and huge windows. So a lot of natural light!

Because life outside of work should also be stress-free, we cover:

• Health care (100% coverage).
• Maternity Leave, Paternity Leave, Second Parent Leave (salary maintained at 100%).
• Vacation days: 8-9 weeks (total) per year - (European summer? ).
• 5 weeks of paid time off (by the state);
• 1-2 additional weeks (RTT, based on our company contract);
• ~11 bank holidays. We shut down entirely twice a year, two weeks in summer and one week in winter to allow everyone to truly recharge and to avoid prolonged slowdowns (especially in the summer). These pauses are part of your total vacation time, giving everyone a real chance to unplug and recharge. No Slack, no email, no FOMO.

We love the diverse perspectives we get from having people from all over the world join us (68% of our team is international), and so we of course support relocation to Paris with:

• Help and sponsored visa process.
• 1 month of Airbnb 100% covered by amo upon arrival.
• Assistance from a trusted relocation agency to find your permanent home.
• Help with french paperwork like opening a french social security account, tax forms, getting your carte vitale (free healthcare) and more.
• French lessons to be fully set with your new Parisian life.
