What follows describes the role and qualifications for joining the team.

Your Role

Our tech team is expanding rapidly to keep pace with the ambitious feature roadmap. We are hiring experienced Software Engineers (Back-end / Ruby) to help build and scale our product. You’ll have the opportunity to help define our roadmap and find the best technical solutions to help our customers. You will also have time to run some experiments and bring new ideas to the table.

Reporting directly to our Tech Lead, you will be responsible for:

• Interacting with the Product Manager to review project specs
• Preparing integration plans, break-downs, and estimations
• Hands-on code implementation, PRs, code reviews, testing, etc.

You'll be working with Michael (co-founder and CTO) along with the product team and the engineering team (web developers, SRE, data scientists).

NB: while we remain open to full-stack expertise, we are looking for people with a strong edge on back-end development using Ruby-on-Rails.

Your Qualifications

Must-haves

3+ years of experience:

• As a back-end or full-stack software engineer - recent experience with Ruby-on-Rails is mandatory
• In tech scale-ups or any similarly agile and fast-paced environment
• On large-scale products where your code was used by thousands of monthly users

Strong communication & collaborative skills (perfectly fluent in English)

Ownership and commitment - we’re looking for owners, not renters

Doer mindset - we are moving fast and we need people who can find the right balance between software craftsmanship and velocity

User-centricity - you are proud of what you build and you share our obsession for amazing user experience

NSFW - you are comfortable building products that are based on uncensored models and content

Bonus points

• Past experience and/or interest in data science and generative AI (NLP, ML, MLOps…)
• Experience working with globally distributed teams
