[Hiring] Builder Developer II/III/IV (Senior Agentic Software Engineer) @ECI Software Solutions

Role Description

ECI is hiring senior-level Builder Developers (Senior Agentic Software Engineers) focused on rewriting how enterprise software is built, tested, and operated using AI.

The Mission:

• Use AI to build autonomous agents and workflows that transform legacy ERP systems into modern, AI-driven platforms.
• Focus on automating workflows and owning the execution of AI-driven modules.

Here are the Builder levels we are hiring:

• BUILDER 2 (Senior): Focuses on Agentic Implementation. They build the agents and can modernize legacy modules with minimal supervision.
• BUILDER 3 (Lead): Focuses on Systemic Orchestration. They design the Guardrail Layers and Eval Frameworks to ensure agents are deterministic, cost-effective, and scalable.
• BUILDER 4 (Principal/Architect): Focuses on The Meta-Platform. They build internal Builder Tools and ensure ERP architecture is ready for Autonomous Operation.

Core DNA (Shared Foundation):

• AI-Native Workflow: Use AI tools to accelerate development, testing, and documentation 10x faster than traditional methods.
• Agentic Implementation: Build, debug, and deploy autonomous agents that navigate complex ERP schemas and business logic.
• Legacy-to-Modern Bridge: Treat 20-year-old legacy systems as puzzles for AI-driven modernization.
• Deterministic Mindset: Build for 100% reliability with automated validation, evals, and guardrails.

What You’ll Actually Do:

• Build Execution Agents that can navigate an ERP schema, identify data discrepancies, and suggest fixes.
• Automate the "Untestable" by using AI to wrap legacy business logic in modern unit tests and documentation.
• Use frameworks like DSPy for prompt engineering and evals.
• Rapid Prototyping to turn a "what if" into a working AI-driven feature in days, not months.

The Stack:

• Python, SQL (Postgres/SQL Server), TypeScript, OpenAI/Anthropic, pgvector/Qdrant, LangChain/LangGraph, dbt, Apache Hop/Airflow, Docker, Weights & Biases, OpenTelemetry.

Qualifications

• The "Early Adopter" Archetype: Experience with GPT-3 and local Llama.
• Agent-First Thinker: Experience building autonomous agents or complex LLM chains.
• The "Manual Task" Hater: Strong aversion to repetitive work and a proactive approach to automation.
• Technically Fearless: Comfort with legacy code and a focus on AI-driven refactoring.
• Rigor over Hype: Understanding the difference between demos and production-grade agents.
• The Tribe Member: Desire to work in an environment that celebrates AI hacks and automation scripts.

Benefits

• The "Final Boss" of Complexity: Opportunity to tackle challenging ERP problems.
• Agentic Autonomy: Freedom to choose models, frameworks, and agent architectures.
• The BUILDER Tribe: Collaboration with like-minded enthusiasts.
• No Red Tape: A straightforward policy of shipping what works.
• The Final Boss: Engage with complex ERP data challenges.
