Ballparkis our answer to making research faster, easier and more accessible. The majority of people conducting research in companies aren't researchers - so let's create a platform that meets them where they are.

We want to build the "Canva of research" and create a research platform that is visual, real-time and filled with pre-made templates, questions and tasks so that every team can get deeper insights that lead to better products.

Since our beta launch in 2023, we've added tons of new Enterprise customers like Monzo, Soldo, Guild, Honeybook and Vodafone.

In summer 2023, we raised a seed round from InReach, Haatch, Caffeinated Capital and Bungalow VC who have invested in amazing companies such as Notion, Soldo and Airtable.

Why join Ballpark?

  • We're biased, of course, but we have a super exciting stack that we've built that includes real-time collaboration, video streaming and data processing.
  • A super talented, close-knit engineering team that helped build the system.
  • An amazing list of customers that are highly engaged in improving the platform and constantly providing feedback.
  • The chance to tackle an industry that is ready for change.

The role

As part of this team lead role, you will be primarily responsible for working with the backend team, managing our Python Django backend with a GraphQL API built to power our new Enterprise platform. You will also be required to always think about our product with security in mind. It is essential that you have strong knowledge in operations and backend technologies to maintain and build out our backend infrastructure to be lightning-fast, secure and highly available.

Ballpark's development team focuses on a culture of curiosity, empathy, learning, knowledge and accountability. We believe in owning and delivering what you work on, always making sure that you provide the best experience for our customers and team. As an early-stage startup, you will be given a lot of space to follow your intuition and work with your team to find the best solutions and tools to build a world-class product.

Requirements

Responsibilities

  • Own, deliver and innovate on new product, operations and infrastructure development for all our customers.
  • Ensure that we are the most secure platform in the space by using best practices and aligning us with ISO enterprise standards.
  • Work alongside the product team to define features, in addition to being responsible for deploying, smoke testing and monitoring your own code once reviewed and in the live environment.
  • Co-own and develop projects with your teammates and peers.
  • Participate in thorough, constructive code reviews, ensuring high code quality and providing insightful feedback that improves the code and helps other team members improve their technical skills.
  • Identify issues with technologies or processes and bring solutions to the attention of their team or tech lead.
  • Demo your work regularly to your teammates and the wider company.
  • Be aligned with the company goals and product roadmap, and drive towards them in your sprint work.
  • Be accountable for key performance and product metrics to ensure the product is stable, performant and secure.

Values and Culture of a Team Lead

  • Ability to drive a feature from start to finish, know where each engineer is at, understand whether those engineers are on track, and provide support and leadership to get them back on track if needed.
  • Senior-level technical ability required to understand and unblock the rest of the team.
  • A great mentor who can elevate the skills and performance of the entire team through effective guidance, knowledge sharing, and continuous development opportunities.
  • The ability to translate business needs into technical implementations and craft solutions that are easy to understand and maintain.
  • Strong communication and empathy skills. Be happy to give pragmatic feedback graciously to your team members. Enjoy teaching as much as you enjoy learning.
