Company Summary:
Slang.ai is redefining customer engagement through conversational AI, making every interaction seamless and efficient. Our mission is to transform the restaurant industry by providing the ultimate voice AI solution for consistently outstanding customer experiences. At Slang.ai, we foster a culture of innovation, inclusivity, and growth, ensuring that every "Slangsta" (employee) feels valued and connected to our broader AI driven impact.
What Your Experience Will Be:
At Slang you would be among our most senior software engineers, driving the development of robust, scalable backend systems that power conversational solutions for full-service restaurants. In this role, you'll leverage your deep JVM expertise and domain-driven design principles to architect and implement systems that seamlessly blend telephony, cloud infrastructure, and AI capabilities into cohesive, maintainable software.
This role has high impact technical leadership responsibilities. As one of our most senior engineers, you'll work across our telephony and platform stack, collaborating closely with our Platform & Data pod and serving as a technical mentor to our broader engineering organization (~10 people total) in software engineering best practices. You'll help establish architectural patterns that ensure our systems are modular, testable, and adaptable to changing requirements.
Within your pod, you'll focus on designing and implementing elegant backend services using Kotlin, crafting thoughtful data models for Firestore, and ensuring our containerized services operate reliably in Google Cloud Platform environments. You'll work with telephony providers like Twilio and conversational AI platforms like Dialogflow to create seamless communication experiences, while also guiding the implementation of proper monitoring and observability solutions. Your architectural decisions and engineering leadership will directly influence the entire engineering team's productivity and the quality of our customer-facing systems.
Why You Belong Here & How You Will Grow:
At Slang Engineering, we cultivate a space where everyone can dream big, own their impact, and innovate boldly – all while having fun and supporting each other along the way. We put an emphasis on collaboration, and we are split into small teams with different responsibilities and ownership. We engage in hack-a-thons to allow people to find time to bring real innovation, unchained from our day-to-day work and priorities. We are a fully remote company, but also have a New York city office space, for those who are local or in town and want a hub.

Our Vision
Calling a business shouldn’t feel like a robot-hostage situation, where you’re forced to listen to horrible music and can't reach a human, while enduring a soulless voice uttering "I'm sorry I didn't quite get that" on repeat for eternity. (shudder) That’s why we started Slang.ai. We use the latest AI and audio wizardry to make transacting via voice so enjoyable it’s more human than human. By 2030, we will save businesses and consumers 1 billion minutes of precious time while transforming voice channels into the preferred mode of communication (it's faster and easier than text).
We have backgrounds building product at companies like Spotify, Buzzfeed, the New York Times, and OpenTable —shipping experiences that have reached hundreds of millions of users. Now, we’re using our backgrounds to start a new culture, one that puts product and human-centered design above all else while fostering constant learning and growth. Sound like something you’d like to be part of? Get on board.
Our Values
Overachiever Fever. We’re overachievers (we don’t know any other way)
Learner Fervor. We take every opportunity to learn (especially when it’s hard)
Humility Ability. We approach each other with curiosity and openness (know-it-alls not welcome!)
SMB MVP. We’re an expert member of our customers’ teams (we earn their trust)
