Job Title: Senior Software Engineer

Location: Warsaw, Poland (Remote)


Although we’re proud of our history, we’re just as excited about the future. We want to create a world-class culture and company that attracts, develops, engages, and retains the nation’s elite talent.

At Salesloft, our Senior Software Engineers are pivotal to our company’s success. You will be a key member of our fast-growing and high-performing team working on new technologies in an environment that supports your technical and professional growth.

You will join a pod of more than 30 fullstack and UI Engineers that are responsible for all of the communication channels in Salesloft -- email, calendar, phone dialer, text messages, and screenshare platforms like Zoom. This is our second team in Poland on this pod, and will start by being focused on developing new, innovative features for the Conversations product. Notably, you will build the first even Zoom app for an enhanced conversation intelligence experience. Interacting with 3rd party APIs and building a secure, performant, and feature-rich data layer that can be consumed by other teams within your pod will be the long-term focus for the team. The tech stack varies from Node, Typescript/Javascript, Elasticsearch, GraphQL, Ruby, Rails, and Elixir.

Working with amazing colleagues who exemplify our ‘team over self’ core value, we will have the opportunity to create impactful and revolutionary software that is changing the way sellers sell. Together, we will have an opportunity to make a difference.


We are seeking a high-performing individual contributor who can accomplish complex tasks with little direction, design and develop solutions for our team’s roadmap work, lead learning sessions, collaborate well across delivery teams, hold a clear understanding of the organization’s goals, and be a strong engineering resource to help deliver features with quality and on-time. You will participate in support channels, and engineering-wide initiatives, provide technical support on key customer calls, and mentor and coach team members who seek opportunities to learn and grow.

On a day-to-day basis, you will be responsible for:

  • Writing secure, scalable, performant code on a microservices architecture
  • Doing deep code reviews for teammates and other pod-mates that have dependencies on your team
  • Ensuring quality across the software development lifecycle
  • Holding the bar for system testability, observability, and maintainability
  • Reviewing metrics, identifying issues, and improving performance of our applications
  • Providing ongoing production support and contributing to incident reviews
