What is a Backend Engineer at Unify?

At Unify, the Backend Engineer role is central to our mission of building the first true system-of-action for go-to-market teams. We are moving beyond the era of mass, cold outreach by building an end-to-end platform for "warm outbound." You will be working at the intersection of high-scale data processing and cutting-edge AI, enabling GTM teams to identify and engage prospects at the exact moment of intent.

This is a high-impact, zero-to-one role. You will work directly with our founders to shape the product roadmap and establish the engineering standards that will define our long-term trajectory. Because we are a high-energy, high-intensity team, you will be expected to own large scopes of work, manage infrastructure, and mentor fellow engineers, all while leveraging a modern tech stack to solve complex engineering challenges.

Getting Ready for Your Interviews

Preparation for Unify should focus on your ability to connect technical implementation to business outcomes. We are looking for engineers who are "customer-obsessed" and capable of translating high-level business ideas into deployed, scalable solutions.

Technical Execution – You must demonstrate deep fluency in our stack (TypeScript, PostgreSQL, Kubernetes). Be prepared to discuss not just how to use these tools, but why they are the right choice for our specific scale and growth trajectory.

System Thinking – We evaluate your ability to think about the "big picture." This includes how your code impacts reliability, how it interacts with other services, and how it enables our users to achieve their GTM goals.

Leadership & Collaboration – As a senior or staff-level engineer, your ability to influence others is as important as your individual output. Show us how you communicate complex technical concepts to non-technical stakeholders and how you foster a culture of high standards.

Interview Process Overview

The Unify interview process is designed to be rigorous, collaborative, and fast-paced. We prioritize real-time problem solving and in-person connection, which is why our roles are onsite in San Francisco or New York City. You should expect a sequence that balances deep-dive technical screens with collaborative sessions that mimic our daily working style.

Our philosophy is to get to know you as a peer. You will spend time with our engineering team and potentially our founders, focusing on both your past accomplishments and your ability to solve the specific technical challenges we face today. We value direct communication, creative problem-solving, and a "builder" mentality.
