The development team has full responsibility for the development lifecycle. This means we plan, develop, test and deploy our software without any other internal or external dependencies.

Our portfolio revolves around an internally built CRM which is now being enhanced with AI capabilities. 

About the product you will be building:

We are building a next-generation AI platform designed to redefine how our company interacts with customers. This isn't just a chatbot; it's a high-performance, multimodal AI ecosystem powered by state-of-the-art Speech-to-Speech (S2S) models, advanced Large Language Models (LLMs), and intelligent orchestration frameworks. Our platform will understand, reason, and respond across text and voice — while seamlessly executing real-time actions to resolve customer needs.

We are aiming for a hybrid architecture of Open Source LLMs, industry-leading proprietary models, and Model Context Protocol (MCP) to enable contextual reasoning, tool invocation, and seamless orchestration across systems. The goal is not just to talk to the customer, but to act on their needs.

What makes this project unique:

The Voice Frontier: We are building low-latency, emotive speech-to-speech pipelines for a truly natural voice channel experience.

Deep System Integration: Our platform connects directly to the company's core systems via MCPs, allowing the AI to access real-time customer context and execute complex workflows.

Self-Evolving Logic: We are developing  an automated QA and evaluation module that continuously analyzes interactions across channels.By programmatically measuring quality, accuracy, latency, and resolution outcomes, we can close the feedback loop, and adapt system behavior in hours, not weeks.

Hybrid Innovation: You’ll work at the intersection of "build vs. buy," integrating the best of the open-source community with custom-built internal infrastructure.

What's in it for you:

You won't just be shipping code; you’ll be part of making this concept evolve and shift.
You’ll join a friendly, experienced team where your voice matters and your contribution shapes real-world outcomes. You’ll work in a modern environment with technologies and practices that help us ship reliable software efficiently.

Role description:

As an AI Engineer on this team, you will build the core intelligence systems behind our multimodal AI platform.You will be responsible for moving beyond simple chat interfaces to build high-performance, real-time systems that handle complex reasoning, deep context retrieval, LLM orchestration, retrieval-augmented generation (RAG) and seamless voice interactions.

• Evaluation, Quality & Alignment: Build and maintain an automated QA module, including LLM-as-a-judge patterns, to measure accuracy, safety, latency, and resolution quality at scale. Translate evaluation insights into systematic models and prompt improvements..
• Model Strategy & Hybrid Integration: Integrate and operate both commercial foundation  models (e.g., OpenAI, Anthropic, Google) and open-source alternatives (e.g., Qwen, Kimi, DeepSeek, Moonshot, GLM), selecting and optimizing models based on performance, latency, cost, and use-case requirements.

We are looking for some of:

• Strong Python and/or Java Engineering Skills: Advanced-level Python development experience, including  asynchronous programming (e.g., FastAPI, asyncio) and building high-performance, production-grade services. Experience with streaming architectures is a strong advantage.
• LLM Application & Multi-Agent Orchestration Experience: Hands-on experience building LLM-powered systems, including multi-step workflows, stateful agents, and tool invocation. Familiarity with orchestration frameworks such as LangChain, LlamaIndex, or LangGraph, particularly in building stateful, multi-turn agents.
• Advanced Retrieval & Context Management: Deep understanding of vector databases (e.g., Weaviate, Qdrant, pgvector, Elasticsearch), semantic search, embedding strategies, and re-ranking techniques. Experience designing and optimizing RAG pipelines.
• Real-Time & Low-Latency Systems: Experience in designing systems that operate under latency constraints, including streaming APIs, event-driven architectures, and performance optimization. Understanding of trade-offs between quality, cost, and response time.
• Evaluation-Driven Development: Experience in implementing evaluation frameworks for LLM-based systems, including automated QA pipelines and LLM-as-a-judge patterns.
• Familiar with API Design: knowledge of RESTful API design, OAuth2

BACKGROUND AND OPPORTUNITY

There are almost 75 million hourly workers in the United States, representing more than half of the entire workforce. Historically, managing hourly employees has been difficult due to high attrition (average of 60%) and high replacement costs (average of $3,200 per employee in retail). The ongoing labor shortage and competition from the gig economy, make it more difficult to attract and retain hourly employees. The top reasons hourly employees leave their jobs are a lack of schedule empowerment, poor communication with employers, and an inability to get paid early. Gen Z and the millennial workforce demand gig-like flexibility, modern technology, and compelling work options. Legion’s mission is to turn hourly jobs into good jobs, serving the hourly workers who make up the majority of the US workforce. We believe in empowering employees and helping employers be efficient and innovative by enabling intelligent automation powered by Legion’s Workforce Management platform to optimize labor efficiency and enhance the employee experience simultaneously.

• Distributed systems: Solid understanding of microservices architecture, asynchronous patterns, and high-volume transaction handling.
• Cloud & containerization: Hands-on experience with AWS and containerized deployments (Docker, Kubernetes).
• Software craftsmanship: Deep familiarity with coding standards, code review practices, CI/CD pipelines, and DevOps principles.
• Testing discipline: Proven ability to write and maintain unit tests, integration tests, and automated test suites - including for AI-generated code.
• Problem-solving: Demonstrated ability to troubleshoot and debug complex, multi-layered systems independently.
• Communication: Excellent written and verbal communication skills; able to document technical decisions clearly for both engineers and non-technical stakeholders.
• Education: Bachelor's or Master's degree in Computer Science, Computer Engineering, or equivalent practical experience.

PREFERRED QUALIFICATIONS AND ATTRIBUTES

• AI-native workflow: You've gone beyond autocomplete — you use AI for architecture brainstorming, test generation, spec drafting, PR summaries, and are actively experimenting with agentic coding tools.
• Workforce management or HCM domain experience: Familiarity with time-and-attendance, payroll, scheduling, or labor compliance systems is a significant advantage.
• Frontend exposure: Working knowledge of JavaScript and either Angular or React.
• Leadership track record: Experience informally leading feature teams, running design reviews, or serving as a technical point of contact for a product area.
• Performance engineering: Prior work on query optimization, caching strategies, or throughput/latency improvements in high-volume applications.
• Agile fluency: Comfortable operating in fast-paced sprint cycles with evolving requirements.
• Integrity and judgment: Demonstrated ethical behavior and sound judgment, including when evaluating AI-generated outputs for correctness, bias, and security implications.

In your interviews, we'll ask you to describe:

• Which AI coding tools you use and how frequently.
• A specific example where an AI tool helped you design, refactor, or debug something non-trivially.
• How you validate and review AI-generated code to catch errors, security issues, or performance problems.
• Your view on the limits of current AI coding assistants and where human judgment remains essential.

We are not looking for performative AI enthusiasm. We are looking for engineers who have genuinely integrated these tools into their craft and can think critically about their strengths and failure modes.
