Full 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 ecommerce. 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?

Fin's websites, including fin.ai, are strategic growth levers for the company — powering storytelling, brand, experimentation, and product discovery. As our Principal Engineer, you will shape the technical direction and architectural evolution of our web platform and systems. You’ll act as the technical leader across our marketing and growth web surfaces. This is a cross-functional engineering leadership role, partnering with marketing, analytics, design, data science, and engineering teams — to ensure our web stack is modern, performant, measurable, and delightful to build on. You’ll operate with a high degree of autonomy and will be accountable for setting the long-term technical strategy for the team and executing against it.

What will I be doing?

As a senior technical leader, you will:

Own and evolve the architecture of Fin's web platform.
Define the long-term technical strategy for the web team, focusing on scalability, performance, developer productivity, observability, and system reliability.
Collaborate closely with marketing, design, analytics, and data science stakeholders to ensure the platform supports their goals with accuracy, performance, and agility.
Lead and influence the design and implementation of MarTech systems for event tracking, attribution, funnel reporting, A/B testing infrastructure, and more.
Partner with engineers across web, infrastructure, and data to create a high-quality, cohesive technical ecosystem.
Mentor and elevate engineers across the team and organisation — providing guidance on architecture, data modeling, system design, and engineering best practices.
Set the standard for technical excellence in reliability, maintainability, code quality, and operational readiness.
Provide technical leadership and insight to Engineering Managers, Product Managers, and executive stakeholders - communicating risks, trade-offs, and opportunities clearly.
Contribute hands-on to the codebase — leading by example and helping unblock and accelerate key projects.

What skills do I need?

We’re looking for someone who brings deep technical expertise, cross-functional leadership, and strong domain knowledge in web systems. You should have:

12+ years of software engineering experience
Experience in a high-scale growth-focused web environment.
A track record of technical leadership and influencing technical direction across multiple teams or departments.
Deep expertise in Next.js and the React ecosystem.
Experience with headless CMS platforms such as Contentful or Sanity - including content modeling, migration, and multi-site architecture.
Experience with infrastructure-as-code (Terraform), cloud platforms (AWS, CloudFront, S3), and deployment platforms (Vercel).
Experience designing or operating experimentation infrastructure - A/B testing frameworks, event instrumentation, attribution systems and tools like Eppo.
Strong understanding of web analytics and data instrumentation - experience with event tracking SDKs, Google Tag Manager, or similar.
Comfortable working in and supporting full-stack codebases - even if this role is not UI-heavy, a solid frontend architecture awareness is valued.
Experience operating in continuous delivery environments with an emphasis on incremental, high-quality shipping.
Exceptional communication skills and a history of collaborating with cross-functional teams (product, marketing, analytics, design, etc.)
A mentorship mindset — proven ability to raise the bar for engineering excellence across a team or organization.

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.

#LI-Hybrid

Policies

Fin has a hybrid working policy. We believe that working in person helps us stay connected, collaborate easier and create a great culture while still providing flexibility to work from home. We expect employees to be in the office at least three days per week.

We have a radically open and accepting culture at Fin. We avoid spending time on divisive subjects to foster a safe and cohesive work environment for everyone. As an organization, our policy is to not advocate on behalf of the company or our employees on any social or political topics out of our internal or external communications. We respect personal opinion and expression on these topics on personal social platforms on personal time, and do not challenge or confront anyone for their views on non-work related topics. Our goal is to focus on doing incredible work to achieve our goals and unite the company through our core values.

Fin values diversity and is committed to a policy of Equal Employment Opportunity. Fin will not discriminate against an applicant or employee on the basis of race, color, religion, creed, national origin, ancestry, sex, gender, age, physical or mental disability, veteran or military status, genetic information, sexual orientation, gender identity, gender expression, marital status, or any other legally recognized protected basis under federal, state, or local law.
