**About Sophia**
Sophia is an end-to-end agentic matchmaker using advanced language and
computer-vision models to deliver deeply tailored introductions.
* We harness AI to help people forge deeper, more meaningful relationships.
* Sophia was founded by two successful serial entrepreneurs, incubated in their venture studio, with leading high profile founders as advisors and investors.
**Role Overview**
Blend full-stack engineering, rapid prototyping, and hands-on user
observation. Sit in on real voice sessions, identify friction or gaps, and
ship improvements quickly across the product and AI layers.
* Move between architecture, backend development, prompting, conversational logic, and real-time debugging.
* Be one of the first engineers shaping how Sophia works in the real world.
**Core Responsibilities**
User-Embedded Product & Engineering
* Join live onboarding calls and member conversations to understand user behavior.
* Identify issues in voice flow, prompting, matching logic, and UX — and translate them into immediate refinements.
* Work closely with founders on building and iterating the end-to-end AI experience.
Full-Stack Feature Development
* Build and maintain features across the stack (front end, back end, data, and AI interfaces).
* Improve workflows for voice interviews, dossier creation, matching, and SMS-based interactions.
* Ship rapid prototypes and production-ready changes in short cycles.
AI + Prompt Integration
* Refine prompt pipelines, conversation logic, and multimodal reasoning flows.
* Work with AI/ML teammates to integrate model endpoints and improve system performance.
* Debug voice, reasoning, or behavioral issues in live environments.
Architecture & Technical Ownership
* Contribute to architectural decisions across voice, vision, memory, and data.
* Help plan and implement new integrations, such as social media ingestion or expanded data sources.
* Build internal tools that accelerate testing, evaluation, and deployment.
Reliability & Observability
* Monitor key user journeys and proactively resolve issues.
* Improve system resilience, logging, and data handling across the platform.
* Ensure responsible management of user data and PII.
**Requirements**
Technical Skills
* Strong experience with modern web technologies on both front end and back end.
* Comfortable working with Python, Node, or similar server-side environments.
* Experience building or integrating AI-powered features (LLM APIs, embeddings, tools).
* Ability to reason across the entire stack — from API design to prompt structure to deployment.
* Strong debugging and problem-solving abilities, especially in ambiguous situations.
Preferred Experience
* Exposure to conversational interfaces, AI agents, or voice systems.
* Prior work in early-stage or fast-moving product environments.
* Experience joining user calls or working closely with non-technical stakeholders.
* Familiarity with event-driven systems, queues, or background workers.
Who Thrives Here
* Smart, fast learner with strong fundamentals.
* Low-ego, humble, and curious — comfortable starting from first principles.
* Enjoys sitting with users, seeing real behaviors, and improving the product based on what they observe.
* Adaptive and willing to move quickly between tasks and problem domains.
Engagement
* Full-time role; contract-to-hire or W2 options available.
* Location flexible (Chicago, Miami, or New York preferred; remote possible).
