Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Remote - **Company:** V'S FINE LIQUOR AND BEER, LLC - **Location:** United States (Remote available) - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Software Debugging, Python (Programming Language), Software Engineering, Systems Integration, Chatbots, Backend, Low Latency, Integration Frameworks, Virtual Agents - **Published:** September 2, 2026 - **Apply:** https://www.builtincolorado.com/auth/login?destination=/job/staff-software-engineer/10963386 ## About the Role * 8+ years of professional software engineering experience, with a track record of owning significant systems end-to-end * Deep experience with backend systems in Python (or similarly strong general backend fundamentals with a willingness to go deep in Python) * Experience designing for reliability and correctness in real-time or latency-sensitive systems * Comfort operating with ambiguity - you can take a loosely defined problem and drive it to a well-architected solution * Strong judgment about when to build for scale vs. when to move fast - and the communication skills to bring others along with your reasoning * Bonus: experience with conversational AI/LLM-based systems, real-time audio/telephony platforms, or integrating with third-party/legacy POS or specialized hardware ## Description Own the architecture and technical direction of conversational AI and voice-ordering systems. Design reliable, low-latency backend services for live drive-thru traffic, lead cross-system integrations with POS and hardware, improve AI evaluation and observability, mentor engineers, and resolve complex production issues involving real-time audio, distributed services, and third-party integrations. The summary above was generated by AI, At Arc, we are on a mission to amplify employees at local businesses using AI. With years of experience building and scaling commerce tools for businesses-from farmers markets and neighborhood coffee shops to global retailers, restaurant chains, and major sports venues-we know how to deliver mission-critical technology that integrates easily, delights customers, and works every time. Voice drive-thru is our first product on that journey: an AI voice agent that takes real orders at the drive-thru speaker, in real time, integrating directly with a business's existing POS and hardware. Done well, this means more revenue, faster lines, and fewer mistakes for the operators we serve. As a Staff Software Engineer, you'll take ownership of the hardest technical problems across our stack including backend and AI systems: designing for reliability, speed and accuracy under live drive-thru traffic. This is a high-leverage, high-autonomy role for someone who wants to shape the technical direction of a fast-moving product, not just execute tickets. What You'll Do * Design and evolve the core architecture of our conversational AI and voice-ordering systems, balancing latency, reliability, and correctness in a live, in-lane drive-thru environment * Lead complex, cross-cutting technical initiatives - from POS and hardware integrations to evaluation and observability of AI agent behavior - that span multiple systems and teams * Set technical direction and standards for the backend, and mentor and onboard new hires. * Partner closely with product and operations to translate the real-world, on-the-ground needs of local business operators into robust technical solutions * Improve how we test, evaluate, and monitor AI agent quality, given the unique challenges of validating non-deterministic, conversational systems * Debug and resolve the gnarliest production issues, especially ones spanning real-time audio, third-party integrations, and distributed services ## Related Videos - [Agentic employees in world's most downloaded FinTech app](https://www.wearedevelopers.com/videos/100123-agentic-employees-in-world-s-most-downloaded-fintech-app) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Chatbots are going to destroy infrastructures and your cloud bills](https://www.wearedevelopers.com/videos/1130-chatbots-are-going-to-destroy-infrastructures-and-your-cloud-bills) - [Swapping Low Latency Data Storage Under High Load](https://www.wearedevelopers.com/videos/746-swapping-low-latency-data-storage-under-high-load) - [Integrate your Cognitive Assistant with 3rd-party DBs and software](https://www.wearedevelopers.com/videos/249-integrate-your-cognitive-assistant-with-3rd-party-dbs-and-software) - [You are not an AI developer](https://www.wearedevelopers.com/videos/1148-you-are-not-an-ai-developer) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this) - [Never delegate the understanding](https://www.wearedevelopers.com/magazine/749-never-delegate-the-understanding) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix)
