Gesture is where technology meets humanity — a place where innovation, emotion, and impact collide. We’re a fast‑growing tech company using AI, machine learning, and intelligent logistics to power a first‑of‑its‑kind platform that connects people and brands through real‑world, tangible experiences. From our mobile app to our B2B Reach
360 platform, Gesture blends data, emotion, and automation to build the future of human connection — at scale.

Inside our Denver Office, you’ll find an environment that moves with the pace and precision of Silicon Valley but with the heart of something far greater.

We run on cutting‑edge tools, creative experimentation, and raw ambition. Every project, every campaign, every moment you work on here matters — because it’s seen, felt, and experienced by real people around the world. At Gesture, you’ll work alongside some of the smartest, most driven operators, engineers, and creatives in the industry — people who think big, move fast, and care deeply about the work they do.

This is a front‑row seat to the future of connection. If you want to help build something that’s changing how the world interacts, welcome to Gesture.

Gesture is investing aggressively in AI‑driven intelligence to power the next generation of marketing and commerce using a gift‑centric approach. Our roadmap focuses on:

• Building intelligence that anticipates, adapts, and compounds—predicting intent, optimizing campaigns in real time, and delivering deeply personalized experiences driven by real‑world behavior, all through systems that continuously learn and improve with every interaction.
• We’re building intelligence directly into the core of how campaigns are planned, executed, and measured—at scale.
• At Gesture, you’re not joining a static Mar Tech company. You’re joining a team building the infrastructure for how brands will compete in a post‑digital‑fatigue world.

Gesture is building the next evolution of emotionally intelligent consumer engagement. As an Engineering Intern, you will work alongside senior engineers and product leaders to develop AI‑driven tools for our Operations (Marketing, Sales, Fulfillment) team to utilize to optimize and scale our model.

This role is hands‑on. You will contribute production‑level code to systems utilized internally to drive automation, keeping our team working on projects that truly move the needle while learning how engineering, product, and data come together inside a fast‑growing technology company.

• Support the design and implementation of data models, predictive pipelines, and recommendation logic for personalization across the internal Gesture ecosystem.
• Contribute to algorithms that translate user behavior into engagement cycles, rewards, and individualized experience pathways.

• Assist in building backend components that power user incentives, behavioral triggers, and reward systems.
• Help develop logic that connects user signals (sending patterns, interaction frequency, referrals, etc.) to loyalty outcomes and campaign eligibility.

• Collaborate with the mobile team (React Native) to integrate AI‑driven recommendations, dynamic feeds, and adaptive notification patterns.
• Develop backend services that support A/B testing, targeted campaigns, personalized prompts, and customer journey flows.

• Work on API integrations between Firebase, Zoho CRM, Segment, Voucherify, and internal data systems.
• Assist in ETL workflows, data ingestion, and ensuring data quality across the ecosystem.
