Senior Full Stack Developer Jobs in Granger, IN (NOW HIRING)

At Motorola Solutions, we believe that everything starts with our people. We're a global close-knit community, united by the relentless pursuit to help keep people safer everywhere. We build and connect technologies to help protect people, property and places. Our solutions foster the collaboration that's critical for safer communities, safer schools, safer hospitals, safer businesses, and ultimately, safer nations. Connect with a career that matters, and help us build a safer future.

We're looking for a Sr Software Engineer to set technical direction for the AI Agent Platform team behind Hyper's emergency response products (Motorola Solutions announced that it acquired Hyper on April 9, 2026).

You'll be a senior technical leader responsible for the architecture of our most critical systems. You'll shape long-term technical strategy, mentor engineers across the team, and own the toughest cross-cutting problems - from real-time AI pipelines and telephony to backend infrastructure and product surfaces. We expect engineers to use AI agents in their own work. But because this is mission-critical software, humans still own quality, judgment, and what ships - and as a Sr Engineer, you set the bar for what "good" looks like.

• Lead the design and operation of real-time voice AI systems that support human 911 telecommunicators at scale.

• Identify and solve the hardest problems in our stack: low-latency audio, streaming, telephony, LLM orchestration, and human-in-the-loop AI workflows.

• Drive engineering excellence across reliability, availability, security, and performance - defining the standards the team operates by.

• Partner with product, design, and operations leadership to translate ambiguous customer and operational problems into technical strategy.

• Mentor engineers; raise the floor and the ceiling of the team's technical work through reviews, design feedback, and pairing.

• Build and evolve evaluation, testing, and observability frameworks for AI-assisted systems.

• Lead incident response and post-incident reviews; own runbook quality and on-call health for the systems the team is responsible for.

• Represent engineering in conversations with public safety customers, partners, and Motorola Solutions stakeholders when deep technical credibility is required.

• You have production software engineering experience, with a clear track record of technical leadership.

• You've designed, shipped, and operated large, complex systems in high-stakes domains

• You are comfortable working across backend, infrastructure, AI pipelines, and product surfaces.

• You can turn ambiguous product or operational problems into clear technical plans for the team.

• You use AI tools daily, but you set the standard for how your team uses them responsibly - speed without compromising quality.

• You raise the engineering bar around tests, observability, code review, security, and clean abstractions.

• You mentor effectively. Engineers around you get better because of how you work.

• You have strong product judgment and care deeply about the humans using what you build.

• You thrive in a small, fast-moving team with high ownership and low ego, and you can scale that culture as we grow.

• You want to work on AI systems that matter beyond demos.

We do not expect every candidate to have all of these. We care more about strong engineering judgment, learning velocity, and ownership than exact keyword matches.

Relevant experience may include:

• Architecting LLM, agentic, or RAG systems in production, including evals and prompt test harnesses at scale.

• Deep expertise in Speech-to-Text, Text-to-Speech, Voice Activity Detection, endpointing, interruption handling, noise filtering, diarization, or audio streaming.

• Telephony and voice infrastructure: PSTN, SIP trunking, PBX, and call routing.

• Real-time communication systems using WebRTC, WebSockets, RTP/SRTP, media streaming, or low-latency audio transport - including operating these systems under production load.

• Real-time, concurrent, or distributed systems using Elixir, Go, Python, Rust or similar languages.

• PostgreSQL and strong data modeling fundamentals at scale.

• Cloud infrastructure on AWS, Azure, or GCP.

• Containerized application environments operated in production.

• Technical leadership in public safety, govtech, healthcare, defense, infrastructure, fintech, or other high-trust domains.
