Role Overview
CallHarbor is transitioning from a traditional telecommunications provider into an intelligent communications platform. We are developing a suite of AI\-driven tools—including automated receptionists, intelligent routing, and VCon\-based analytics—designed to convert raw voice data into structured business intelligence.
We are seeking a Lead Software Engineer to serve as the primary technical architect and delivery lead. This role is designed for an engineer who excels at foundational coding while managing a high\-velocity delivery model that integrates agentic AI workflows and specialized external contributors.
Core Responsibilities
* Technical Architecture \& Execution: Lead the design and implementation of core platform features. You will oversee multiple parallel workstreams, ensuring architectural consistency across the stack.
* Engineering Orchestration: Act as the primary lead for the platform. You will scope technical work packages, manage contributions from specialized freelance or outsourced partners, and maintain high standards through rigorous code reviews.
* AI\-Augmented Development: Standardize the use of agentic coding tools (e.g., Claude Code, Cursor) within our development lifecycle. You will define the protocols for AI\-assisted code generation, testing, and documentation to maximize organizational velocity.
* System Integrity \& Security: Serve as the final authority for production deployments. You will maintain and extend critical infrastructure, including authentication, audit logging, and rate\-limiting, ensuring compliance with data privacy standards.
* Roadmap Translation: Convert product requirements into executable technical specifications. You will balance the immediate need for delivery with the long\-term requirement for platform stability and scalability.
Technical Stack
* Backend: Python, FastAPI, Async SQLAlchemy, Alembic, Redis.
* Frontend: React, TypeScript, Vite, React Query, Tailwind.
* Data: PostgreSQL, VCon (Virtual Contact) standards.
* Infrastructure: Integrations with third\-party Voice AI and UCaaS providers.
* AI: Anthropic Claude API; integration of agentic tools into daily workflows.
Qualifications
* Demonstrated Impact: A portfolio of shipped production services. We prioritize evidence of sound technical judgment and successful delivery over specific years of tenure.
* Workflow Engineering: Proven ability to integrate AI coding agents into the development process. You understand the limitations of these tools and can implement the necessary guardrails to ensure high\-quality output.
* Core Proficiency: Expert\-level command of Python or TypeScript, with working proficiency in the other. Deep experience with asynchronous patterns and relational data modeling is required.
* Domain Expertise: Experience in Telephony, VoIP, or highly regulated/integration\-heavy industries is strongly preferred.
* Contributor Management: Experience directing external technical contributors, including scoping requirements and managing remote code integration.
* Security Mindset: A proactive approach to application security, data encryption, and robust audit trails.
Professional Profile
You are a systems thinker who prioritizes functional software over theoretical perfection. You possess high agency and are comfortable setting technical direction and making definitive architectural decisions in an evolving environment.
