Job description

About Us

At Encord, we're building the AI infrastructure of the future. The biggest challenge AI companies face today is not half as glamorous as the outside world may think: it's all about data quality. In fact, the success of any AI application today relies on the quality of a model's training data — and for 95% of teams, this essential step is both the most costly, and the most time‑consuming, in getting their product to market.

As ex‑computer scientists, physicists, and quants, we felt first‑hand how the lack of tools to prepare quality training data was impeding the progress of building AI. AI today is what the early days of computing or the internet were like, where the potential of the technology is clear, but the tools and processes surrounding it are still primitive, preventing the next generation of applications. This is why we started Encord.

We are a talented and ambitious team of 100+ working at the cutting edge of computer vision and deep learning, backed by top investors, including CRV and Y Co‑B, leading industry executives like Luc Vincent, former VP of AI at Meta, and other top Bay Area leaders in AI. We are one of the fastest growing companies in our space and consistently rated as the best tool in the market by our customers. We have big plans ahead and are looking for a rockstar Growth Engineer to join our team!

About The Role

We're looking for a technically‑minded Growth Engineer to architect the future of our digital customer journey. This is an exciting opportunity to join our Growth team at the intersection of engineering and data‑driven marketing, where your work will directly impact how potential customers discover, engage with, and ultimately choose our platform. You'll build next generation web applications, engineer sophisticated attribution systems that uncover new growth opportunities, and create new growth loops to accelerate our funnel throughput.

As an early‑career member of our growth engineering team, you'll have the autonomy to experiment with cutting‑edge personalization technologies, build AI‑powered systems, and solve complex technical challenges that directly translate to revenue growth. If you're excited about applying engineering principles to growth problems and drive measurable business impact, this role is for you.

Responsibilities

• Design and implement dynamic, personalized web experiences that adapt in real time based on user behavior, traffic source, and engagement patterns to maximize conversion throughout the funnel
• Build sophisticated attribution and tracking systems that capture micro‑conversions and behavioral signals, uncovering optimization opportunities others miss
• Analyze CRM, product usage, and behavioral data to identify drop‑off points, then engineer targeted projects that improve pipeline velocity
• Improve predictive scoring models and intelligent content routing that delivers the right messaging to the right prospect at the right time
• Create interactive product demos, applications using React that qualify leads while providing genuine value to prospects
• Engineer A/B testing frameworks and platform analytics pipelines that enable rapid experimentation across the entire growth stack
• Build integrations between marketing tools, CRM systems, and our data warehouse to create a unified view of our customer journeys and enable sophisticated multi‑touch attribution

About You

• You have a degree in Computer Science, Engineering, Mathematics, or related quantitative field with demonstrable projects showcasing both technical depth and business acumen through internships or entrepreneurial ventures
• You bring proficiency in HTML, CSS, JavaScript, and exposure to modern front‑end frameworks through coursework, personal projects, or internships
• You have strong attention to detail, delivering high‑quality work and demonstrating ownership of projects from inception to completion
• You understand web fundamentals including performance optimization principles and have used modern CMS platforms
• You're eager to expand your skills in Python and SQL for data analysis, with basic understanding of how to query databases and manipulate data to derive insights
• You're comfortable with AI‑powered development tools like Claude Code, Cursor, or Copilot and have a strong appetite for using them to ship code faster – viewing these tools as essential accelerators for modern engineering
• You excel at first‑principles thinking, breaking down complex funnels into constituent parts to identify the highest‑leverage opportunities for technical intervention

What We Offer

- Competitive salary, commission and equity in a hyper growth business.

- Strong in‑ culture: most of our team is in the office 3+ days a week.

- Room to grow into anything you choose to – a year ago we were 50 people, now we're 100+. We'll be growing insanely fast over the next 24 months and you'll have all the opportunities for growth as you can handle.

- 25 days annual leave a year + public holidays.

Encord offers a unique opportunity to be part of a startup with a clear mission and vision. You will get to explore and build services enterprise AI use cases across many different industry verticals such as healthcare, surveillance, retail, agriculture and many more.

Our work is at the cutting edge of computer vision and deep learning, which also includes working on solving unsolved problems within those fields.
