Responsibilities

• Build AI-Powered Backend Systems: Design and build backend services using Python, FastAPI, and PostgreSQL to support real-time AI interactions and large-scale data flows, with direct contribution to AI-powered capabilities such as agentic workflows, LLM orchestration, and content pipelines.
• Shape Platform Architecture: Define service boundaries, system interfaces, and scalable design patterns that form the architectural foundation of our AI platform.
• Productionize AI Capabilities: Integrate backend systems with modern LLM providers (e.g., OpenAI, Anthropic) and implement reliable orchestration, routing, error handling, guardrails, telemetry, and deep observability for performance and reliability.
• Collaborate Cross-Functionally: Partner closely with our Labs team, product managers, and designers to take early AI agent concepts and turn them into scalable, production-ready features for our international products.
• Mentor Engineers: Support the growth of other engineers through pairing, code reviews, and ongoing technical guidance.

Requirements

• Technical Experience: 4+ years of professional software engineering experience building and shipping production backend systems, APIs, and microservices used by real customers.
• Backend & Cloud Skills: Strong proficiency in Python, FastAPI, PostgreSQL, and AWS cloud services, with a deep understanding of distributed systems, architecture, and data modeling.
• Agentic AI Experience: Proven experience designing, building, and deploying production-grade agentic AI workflows — including multi-step reasoning, tool/API orchestration, and LLM-as-judge or eval-driven quality gates — serving real end users at scale.
• Technical Judgment: Excellent debugging skills and a proven ability to deliver production-ready, highly reliable systems.
• Collaboration & Communication: Comfortable operating in fast-paced, iterative environments, with strong cross-functional communication skills.

Qualifications

• BA or BS in Computer Science or equivalent practical experience.
• Experience with performance optimization for backend systems, including monitoring, profiling, and tuning for scale.
• Hands-on experience building AI-powered product features, including LLM APIs, RAG pipelines, or agentic workflows in a production environment.
• Familiarity with AI/ML infrastructure including vector databases, model serving, and cost/latency optimization for LLM-powered features.
• Strong opinions on testing, automation, and operational robustness.
• Prior experience working on products for legal, compliance, or other regulated professional domains.

Benefits

• Hybrid Work Model: Flexible hybrid working environment (2-3 days a week in the office depending on the role).
