Android Application Engineer

AI is changing how the world communicates and LILT is leading that transformation.

Were on a mission to make the worlds information accessible to everyone regardless of the language they speak. We use cutting-edge AI machine translation and human-in-the-loop expertise to translate content faster more accurately and more cost-effectively without compromising on brand voice or quality.

At LILT we empower our teammates with leading tools global collaboration and growth opportunities to do their best work. Our company virtuesWork together win together; Find a way or make one; Quicker than they expect; Quality is Job 1guide everything we do. We are trusted by Intel Corporation Canva the United States Department of Defense the United States Air Force ASICS and hundreds of global Enterprises. Backed by Sequoia Intel Capital and Redpoint were building a category-defining company in a $50B global translation market being redefined by AI.

LILT is looking for an Android Application Engineer to join the team building LILT Converse our on-device instant translation application. Converse enables secure real-time speech translation without an internet connection making it the go-to solution for government defense and enterprise teams operating in communication-sensitive or connectivity-constrained environments. You will work at the intersection of cutting-edge on-device AI and polished mobile UX building software that runs large multilingual speech models directly on Android hardware leveraging Qualcomm Snapdragon AI acceleration. This is a high-impact role on a product that is moving quickly.

As the Android engineer on Converse you will own the Android application end-to-end from architecture and on-device ML integration through performance tuning release and reliability in the field working closely with ML product and design on a small senior team. You will architect new features integrate on-device ML models optimize performance manage large local model assets and ensure rock-solid reliability in the field. You will ship capabilities like multilateral translation (simultaneous 3 language conversations) utterance management kiosk deployment modes and enterprise configuration. You will be comfortable reasoning about hardware constraints APK packaging sideloading workflows and the tradeoffs of running multi-gigabyte inference workloads on mobile SoCs.

We are looking for someone who thrives in a fast-moving startup environment and takes pride in shipping software that works in the real world under demanding conditions.

This position may require access to U.S. government systems facilities or controlled information. Candidates must be U.S. citizens or nationals or otherwise eligible to obtain any required government access authorization. LILT will consider all applicants and will work with selected candidates to determine applicable requirements.

Our founders Spence and John met at Google working on Google Translate. As researchers at Stanford and Berkeley they both worked on language technology to make information accessible to everyone. While together at Google they were amazed to learn that Google Translate wasnt used for enterprise products and services inside the quality just wasnt there. So they set out to build something better. LILT was born.

LILT has been a machine learning company since its founding in 2015. At the time machine translation didnt meet the quality standard for enterprise translations so LILT assembled a cutting-edge research team tasked with closing that gap. While meeting customer demand for translation services LILT has prioritized investments in Large Language Models human-in-the-loop systems and now agentic AI.

With AI innovation accelerating and enterprise demand growing the next phase of LILTs journey is just beginning.

What sets our platform apart:

• Brand-aware AI that learns your voice tone and terminology to ensure every translation is accurate and consistent

• Agentic AI workflows that automate the entire translation process from content ingestion to quality review to publishing

• 100 native integrations with systems like Adobe Experience Manager Webflow Salesforce GitHub and Google Drive to simplify content translation

• Human-in-the-loop reviews via our global network of professional linguists for high-impact content that requires expert review

• Featured in The Software Reports Top 100 Software Companies!

• LILT makes it onto the Inc. 5000 List.

• LILTs continues to be an intellectual powerhouse holding numerous patents that help power the most efficient and sophisticated AI and language models in the industry.
