Mobile Application Developer

INFICON•East Syracuse, NY

About The Position

As a Mobile Application Developer (Software Developer) on our Engineering team, you will build and evolve the iOS and Android apps that HVAC/R technicians rely on in the field. You will design features that pair phones with our service tools over Bluetooth Low Energy (BLE), and Wi-Fi, and NFC, capture and visualize live sensor data (pressure, temperature, refrigerant mass, micron levels, combustion readings), and embed AI capabilities that turn raw data into clear, actionable guidance for the technician. This role sits at the intersection of mobile engineering, embedded device communication, and applied AI. You will partner closely with firmware engineers, product managers, UX designers, and working HVAC/R technicians whose feedback shapes every release. This role is crucial for unifying the user experience across all service tools, protecting intellectual property, consolidating development efforts for cost efficiency, and building internal capability and agility for connectivity and scalability requirements.

Requirements

3+ years of professional mobile development, with shipped apps on the App Store and/or Google Play.
Strong skills in at least one of: native iOS (Swift / SwiftUI / UIKit), native Android (Kotlin / Jetpack Compose), or a major cross-platform framework (React Native or Flutter).
Demonstrated experience integrating AI/ML into a real product — running on-device models with Core ML, TensorFlow Lite, or ML Kit.
Production experience integrating mobile apps with Bluetooth Low Energy peripherals or other wireless hardware.
Understanding of GATT, pairing, background modes, and radio environments.
Solid grasp of REST/JSON, authentication (OAuth 2.0 / OIDC), real-time data handling (WebSockets, MQTT, or similar), and local persistence (SQLite, Core Data, Room).
Strong testing habits (unit, UI, and device testing), CI/CD for mobile, source control with Git, and clear written and verbal communication.
Bachelor’s degree in Computer Science, Software Engineering, or equivalent practical experience.

Nice To Haves

Comfort working across both iOS and Android platforms.
Experience with OTA firmware update flows initiated from a mobile app.
Familiarity with field service management (FSM) integrations — ServiceTitan, Housecall Pro, FieldEdge, BuildOps, Salesforce Field Service, or similar.
Experience generating PDF service reports, e-signatures, and customer-facing documentation directly from a mobile app.
Contributions to open-source mobile, BLE, or AI tooling.
Direct experience building apps for the HVAC/R, refrigeration, plumbing, electrical, or broader skilled trades market — or for field service technicians in any industry.
Familiarity with HVAC/R concepts: refrigeration cycles, superheat/subcool, evacuation and micron readings, refrigerant types (A2L and beyond), combustion analysis, EPA Section 608 reporting, and AHRI/ASHRAE workflows.
Experience shipping on-device AI features at scale — model quantization, latency tuning, hybrid on-device / cloud inference patterns.

Responsibilities

Design, build, and maintain features for our iOS (Swift / SwiftUI) and Android (Kotlin / Jetpack Compose) apps, with selective use of cross-platform frameworks (React Native or Flutter) where appropriate.
Build clean, intuitive UIs optimized for one-handed use in various field conditions.
Implement an offline-first architecture so technicians can keep working in areas with no connectivity, then sync cleanly when they’re back online.
Write well-tested, maintainable code with strong attention to performance, battery life, and crash-free sessions.
Make AI-assisted development a core part of how you work, using AI coding assistants and agentic tools to accelerate development while maintaining high code quality, security, and maintainability.
Own and extend the mobile-side stack that pairs and communicates with HVAC/R service instruments over Bluetooth Low Energy (BLE), Wi-Fi Direct, and NFC, including connection management, reconnection logic, and firmware-version compatibility.
Implement reliable streaming and logging of live sensor data — system pressures, superheat/subcool, vacuum levels, refrigerant charge, temperature differentials, combustion readings, and leak-rate data.
Collaborate with firmware engineers on BLE GATT profiles, message schemas, OTA firmware updates pushed through the app, and diagnostic flows for field troubleshooting.
Integrate with adjacent ecosystems used in the trade: refrigerant tracking and reporting platforms, EPA Section 608 compliance workflows, dispatch / field service management (FSM) systems, and customer-facing report delivery (PDF, email, e-sign).
Help evolve our SDK so third-party HVAC/R apps can talk to our tools.
Partner with product managers, UX designers, firmware engineers, and cloud/back-end engineers to ship end-to-end features.
Participate in field visits and ride-alongs with HVAC/R technicians to observe real installs, start-ups, and service calls, and translate observations into product improvements.
Contribute to code reviews, architecture discussions, sprint planning, and engineering hiring.
