Job description

Fin is the AI Customer Agent company on a mission to help businesses provide perfect customer experiences. Our AI Agent Fin is the highest‑performing AI Customer Agent on the market today, enabling businesses to deliver impeccable, always‑on customer support across the customer journey – from service, to sales, to e‑commerce. Powered by our own AI models, Fin resolves complex customer issues end‑to‑end across every channel, with minimal set‑up and integration. Fin can also be combined with our natively integrated Intercom help desk for one single system that is designed to meet the needs of modern day support teams. Founded in 2011, Fin became one of the fastest growing companies and remains one of the largest private software companies in the world with nearly 30,000 global businesses using our products to transform their customer support. Driven by our core values, we push boundaries, build with speed and intensity, and relentlessly deliver incredible value to our customers.

What's the opportunity?

At Fin, you will be a product engineer – someone who solves real customer problems through a smart and efficient application of your technical knowledge and your tools. You’ll be part of one of our multidisciplinary product teams, where you will build both back‑end and front‑end systems and work closely with designers, product managers, researchers, and data analysts. We’re facing many exciting scaling challenges and we’re building a robust platform where your expertise can be applied to areas such as building a beautiful messenger composer, rule matching, deliverability, security, app availability and machine learning, to name a few.

What will I be doing?

As an experienced engineer you will

• Develop technical plans and contribute to our technical architecture as we scale our products to serve tens of millions of people every day.
• Write Ruby code, which knits together a lot of AWS, infrastructure, platform and SaaS technologies that form the core of Fin's backend infrastructure.
• Ship a change to production on your first day and a feature in your first week. That “day one” change is automatically deployed to production along with around 100 other deployments each weekday.
• Build using the best tools in the industry. We invest heavily in AI‑powered developer tools that remove friction and help you focus on solving meaningful problems.
• Grow your team’s capacity by mentoring other engineers and interviewing candidates. This is a chance to be an integral part of building and growing a team.

What skills do I need?

• 5+ years of industry experience in a software engineering role, preferably building a SaaS product. You can demonstrate significant impact that your work has had on the product and/or the team.
• Deep knowledge of a high‑level programming language (for example, Ruby, Python, Javascript, etc.). If you don’t know a language we use, that’s okay – we think great people can learn quickly or introduce us to better ways of working.
• Experience collaborating directly with product teams and designers, and a proven track record of delivering value to customers or users. Engineers at Fin are pragmatists who work closely with others on cross‑disciplinary teams.
• Experience with distributed systems.

Benefits

We are a well treated bunch, with awesome benefits! If there’s something important to you that’s not on this list, talk to us!

• Competitive salary and equity in a fast‑growing start‑up
• We serve lunch every weekday, plus a variety of snack foods and a fully stocked kitchen
• Regular compensation reviews – we reward great work
• Pension scheme & match up to 4%
• Peace of mind with life assurance, as well as comprehensive health and dental insurance for you and your dependents
• Flexible paid time off policy
• Paid maternity leave, as well as 6 weeks paternity leave for fathers, to let you spend valuable time with your loved ones
• If you’re cycling, we’ve got you covered on the Cycle‑to‑Work Scheme. With secure bike storage too
• MacBooks are our standard, but we also offer Windows for certain roles when needed.
