Job Description

About Mixpanel

Mixpanel is an event analytics platform for builders who need answers from their data at their fingertips—no SQL required. When everyone in the organization can see and learn from the impact of their work on product, marketing, and company revenue metrics, they are poised to make better decisions.

Over 9,000 paid customers, including companies like Netflix, Pinterest, Sweetgreen, and Samsara, use Mixpanel to understand their customers and measure progress. Our commitment is to provide the most comprehensive and reliable analytics platform accessible and trusted by all.

About The Role

Mixpanel engineering is a small team that works quickly, prioritizing getting value to customers and iterating to make those experiences even better. We offer the most powerful product analytics tool while still focusing on making the user experience delightful. The full stack engineers have the freedom to move about the stack to deliver value to customers without being blocked by ownership silos. This means doing everything from building snappy UIs and fast and reliable services to leveraging our powerful query engine to get the customers answers that help them deliver great products. We are looking for folks who seek to understand and own customer problems, participating in every step of the development life cycle from ideation to delivery and maintenance. We encourage ownership and autonomy—if you see customer pain points, you will be empowered to fix them. There is no "not my problem" at Mixpanel. All customer problems are ours to fix. We believe that our UX is a key differentiator, and we invest heavily in UI, aiming for a snappy and intuitive experience. We believe in Product-Led Growth, that even enterprise adoption of software tools starts with individual users and the way to get there is through creating a user experience that gets customers to answers quickly.

Responsibilities

At Mixpanel Engineering, Product, and Design (EPD) work closely in pods to define the product and experiences. You'll be collaborating closely with your EPD team to create a vision for delightful and intuitive UX, then work to deliver the most impactful features for our customers. You'll be owning key pieces of the product, maintaining them, and always advocating for improvements to make the user experience even better, adding to our growing shared components library and expanding our design system. You’ll be working on our web app, which is built in Python, running Django, with an open source JavaScript framework running the front end. Everything is run on Google Cloud Platform, using Kubernetes and Docker for orchestration and containerization of our services.

A typical project requires working across our stack, creating endpoints for your feature as well as developing and deploying the UI. Here are some projects we've worked on in the past to give you an idea of what to expect.

A way for customers to share their metrics publicly, a pain point for customers who want to easily share their data on social media or with executive leadership. This feature required keeping an eye on security so unintentional data would not be leaked for customers, but would enable easier collaboration.

We rebuilt our Live View from the ground up and rebranded to Events. Our goal was to improve users’ trust and make debugging their data and query results easier. With these goals in mind, we removed a number of limitations from Live View, improved key work flows, and tightened the UX. We also drastically simplified both the back-end and front-end architecture resulting in a more performant and maintainable product. The end result is a more powerful tool for our users and a simpler codebase for our developers.

We revamped our dashboards UI to improve the workflow for creating and saving analyses that also had the nice side effect of making our data model clearer. This required us to iterate and polish while learning more about how customers used and worked around our product in their day to day. We applied these learnings to smooth our workflows even more while continuing to set the stage for more series of improvements.

We redesigned our query builder to allow users to instantly see the results of their changes on one screen. This was required balancing competing requirements of visual space for the query builder and the ability to see two things at once, resulting in a more intuitive UX.

We made segmentation faster allowing users to customize what they can compare at the query time vs deciding everything they will ever need at the time they develop your product.

What we're looking for

We are hiring full stack engineers with 2-4 years of professional experience working across the UI, API, and DB layers.
You take ownership of problems with a focus on delivering value to users/customers.
You can deliver solutions that are pragmatic in approach.
You have experience with web application architecture and principles.

Compensation

Variable compensation type is determined by your role and level. In addition to the cash compensation provided, this position is also eligible for equity consideration and other benefits including medical, vision, and dental insurance coverage.

💬 Potential Interview Questions

How do you balance user experience and performance when building fullstack features?
By designing minimal, responsive UIs and pairing them with optimized backend queries and endpoints to ensure fast, intuitive interactions.
What challenges do you face when working across the UI, API, and DB layers, and how do you resolve them?
Challenges include data inconsistency, latency, and tight coupling; solutions involve clear contracts, API versioning, and separation of concerns.
How would you optimize a Django-based backend serving high-traffic analytics data?
Use database indexing, query caching, pagination, async tasks, and profile queries to identify bottlenecks.
What is your approach to designing an intuitive and snappy user interface in a data-heavy web app?
Prioritize essential user actions, use skeleton loaders or optimistic UI, and reduce cognitive load through progressive disclosure.
How do you ensure consistency and reusability in a shared component library?
By enforcing design system rules, writing composable components, documenting usage, and regularly auditing for redundancy.
Describe a time you simplified both frontend and backend architecture.
Example: Refactored complex UI logic into reusable hooks and simplified backend endpoints into a single query abstraction layer.
How do you ensure data security when building features that involve data sharing (e.g., public dashboards)?
Implement access control, token-based links, audit logs, and clear user permissions to prevent unauthorized data exposure.
How do you work with Product and Design to shape a new feature from idea to deployment?
Engage early in ideation, prototype collaboratively, provide technical constraints, and iterate based on user feedback.
What are the benefits of containerization with Docker and orchestration via Kubernetes in your development workflow?
Enables reproducibility, scalability, isolation, and consistent deployments across environments.
How do you handle trade-offs between building a perfect solution and shipping quickly?
