Our requirements

  • Significant hands-on engineering experience, typically 10+ years, with strong backend/platform engineering depth.
  • Recent hands-on experience building and operating production backend/platform systems, with full comfort going deep into code, APIs, infrastructure, observability, debugging, and production tradeoffs.
  • Proven experience building and shipping production-grade AI/LLM systems such as RAG, agent workflows, tool-calling systems, AI APIs, or LLM-powered product capabilities.
  • Strong programming experience, preferably in Python and/or backend service stacks used for production APIs and distributed systems.
  • Deep understanding of API design, service boundaries, SDKs, integration patterns, reliability, testing, observability, performance, and cost optimization.
  • Practical experience with LLM application architecture: context engineering, retrieval patterns, tool use, structured outputs, orchestration, fallback handling, and evaluation.
  • Ability to build evaluation and validation systems for AI applications, including golden datasets, scenario-based tests, regression checks, and quality gates.
  • Experience deploying and operating cloud-based production systems on AWS, GCP, Azure, or similar platforms.
  • Strong technical judgment and ability to make tradeoffs across speed, reliability, safety, cost, developer experience, and business impact.
  • Ability to lead through hands-on technical contribution: writing code, creating reference implementations, reviewing designs, mentoring engineers, and turning ambiguous platform needs into working systems.
  • Proven ability to influence across teams through architecture reviews, design documents, technical standards, mentorship, and hands-on partnership.

Optional

  • Experience building internal developer platforms, SDKs, shared services, or paved-path tooling.
  • Hands-on experience with LLM observability/evaluation tooling such as Langfuse, LangSmith, OpenTelemetry-based tracing, or similar tools.
  • Familiarity with LangChain, LangGraph, LlamaIndex, Semantic Kernel, or custom orchestration frameworks.
  • Experience with vector databases, embedding workflows, semantic search, retrieval tuning, and RAG productionization.
  • Experience with AI-native engineering workflows using tools like Cursor, GitHub Copilot, Claude, ChatGPT, or similar tools.
  • Experience writing technical blogs, internal engineering guides, architecture documents, or enablement material that helps engineering teams adopt new practices.
  • Experience leading technical standards or architecture forums across multiple engineering teams.

Your responsibilities

Build the AI platform foundations
  • Write and ship production code for core AI platform services, APIs, orchestration components, evaluation systems, SDKs, and internal developer tools.
  • Design, build, and operate reusable AI platform capabilities such as chat APIs, RAG services, summarization, classification, semantic search, prompt/workflow execution, and agent orchestration.
  • Build high-quality APIs, SDKs, templates, and reference implementations that product teams can adopt with minimal friction.
  • Create production-ready orchestration patterns for retrieval, tool use, validation, fallback handling, memory/state management, and human-in-the-loop workflows.
  • Stay close to implementation details by reviewing PRs, debugging production issues, improving reliability, and making pragmatic technical tradeoffs with the team.
  • Partner with SRE, Security, Platform, and Product Engineering teams to ensure the platform is reliable, scalable, secure, observable, and cost-aware.
    • Own evaluation, reliability, and production readiness
  • Build evaluation harnesses for LLM-powered systems, including curated test sets, scenario-based evaluations, regression checks, quality gates, and release criteria.
  • Implement AI observability practices such as tracing, prompt/version tracking, output quality monitoring, latency tracking, token/cost visibility, and production feedback loops.
  • Design safe defaults for AI systems, including structured outputs, tool permissions, prompt-injection awareness, data handling controls, fallback paths, and failure-mode handling.
  • Ensure AI capabilities are built with strong production fundamentals: testing, monitoring, rollout strategy, incident readiness, performance tuning, and cost management.
  • Help teams move from prototypes to production by identifying gaps in reliability, observability, security, evaluation, and operational readiness.
    • Drive AI adoption across the company
  • Establish internal standards for building production AI systems through patterns, standards, documentation, code examples, architecture reviews, and technical enablement.
  • Work directly with product teams to help them adopt the platform, unblock implementation challenges, and turn early AI ideas into production-ready features.
  • Lead technical design reviews and architecture forums for AI systems, ensuring teams make sound decisions around quality, safety, reliability, and maintainability.
  • Identify repeated friction across teams and convert it into reusable platform capabilities.
  • Help raise AI engineering capability across the company through internal demos, enablement sessions, office hours, technical write-ups, and engineering blog posts.
    • Lead through technical influence
  • Act as a hands-on technical leader and multiplier, not just an advisor.
  • Set technical direction for complex AI platform areas and align stakeholders across Product, Engineering, Security, SRE, and Data.
  • Mentor engineers on production AI engineering practices, backend design, system reliability, evaluation strategy, and AI-native development workflows.
  • Help teams use AI-assisted engineering tools responsibly to improve development speed, testing, debugging, documentation, and iteration without compromising quality.
    • What This Is Not
  • Not a data science role focused on analysis, experimentation, or dashboards.
  • Not an ML research role focused on training foundation models from scratch.
  • Not a prompt-only role without ownership of production systems.
  • Not building one-off AI features for a single product line.
  • Not an architecture-only role where you primarily create diagrams, review designs, or delegate implementation to others.
  • Not a people-management role. You will influence, mentor, and lead through technical depth, but this is an individual contributor position.
