Job Description

About Algolia

Algolia is the leading Search & Discovery API company, powering over 1.5 trillion queries per year for 10,000+ customers worldwide. Performance, scalability, and developer experience are at the heart of our mission. We maintain high-quality SDKs across a dozen languages and live by our core values: Grit, Trust, Candor, Care, and Humility.

The Team

You’ll join our 8-person, cross-functional GenAI Platform squad. We build and operate a Python API that lets developers define, deploy, and manage autonomous multi-agent workflows—leveraging LLMs, vector-search/RAG, external APIs, memory, and custom logic. Our platform handles agent life-cycle, context routing, error recovery, telemetry, and cost controls, making it simple to assemble complex GenAI-driven features.

The Opportunity

As our next Software Engineer, you will be pivotal in evolving our platform from its Beta launch into an enterprise-ready agent ecosystem. You’ll own fast-follow capabilities, broaden our LLM provider integrations, enhance observability, and harden multi-agent coordination. Your work will accelerate partner adoption and lay the groundwork for compliance and at-scale performance.

Your Role Includes

  • Backend API Development & Migration
    Design, implement, and maintain Python APIs to achieve sub-100 ms SLAs on cached calls, containerize for GCP, and ensure zero-downtime rollouts.
  • Agentic “Tool” Integration
    Extend our orchestration engine to treat RAG (vector-search + prompt templates) as a first-class tool; build and maintain SDK adapters for leading LLM providers and vector stores.
  • Production Hardening & Best Practices
    Enforce rigorous type-hinting, linting, CI/CD, smoke tests, and full coverage; automate canary deployments and performance tuning in a microservices environment.
  • Observability, Security & Cost Controls
    Instrument detailed telemetry (cache hits/misses, API-call metrics, LLM costs); build dashboards for internal teams; implement RBAC, audit logging, rate-limiting, and per-tenant isolation.
  • Customer Enablement
    Partner with technical customer teams and Solutions Engineers to create documentation, demos, and sample apps that accelerate onboarding and drive adoption.

Day-to-Day

  • Participate in agile rituals (planning, stand-ups, reviews, retrospectives)
  • Pair- or mob-program on major features (e.g., multi-agent recovery logic, new LLM adapters)
  • Write and review high-quality Python code and RFC-backed pull requests
  • Keep runbooks and API specs “always green” in Confluence
  • Troubleshoot production issues via logs and roll out hot-fixes as needed

Key Projects & Initiatives

  • Beta Fast-Follow: semantic & response caching, multi-vendor routing logic, enterprise SLA codification
  • Orchestration Enhancements: dynamic tool-chaining, context routing improvements, dead-letter handling
  • Telemetry Dashboards: cost-savings insights, request-prioritization controls
  • Python SDK & Sample Apps: robust client library and reference multi-agent workflows

You Might Be a Fit If You Have

  • Python & API Design: 3+ years building versioned REST APIs in FastAPI or Django REST Framework, with strong type safety and unit tests
  • Generative-AI Expertise: hands-on experience integrating LLM providers and designing multi-agent orchestration logic in Python
  • Microservices Production Skills: familiarity with Docker/GCP, performance tuning, canary rollouts, and low-latency caching
  • Observability & Security Acumen: experience instrumenting telemetry, implementing RBAC/audit logging, rate-limiting, and multi-tenant isolation
  • Collaborative Mindset: proven ability to thrive in pair/mob programming, contribute to RFCs, and uphold collective code ownership
  • Bonus Skills: Terraform/IaC, advanced GCP services (Cloud Run, Pub/Sub), React/TypeScript, experience with Algolia’s search ecosystem

Our Values in Action

  • GRIT: Navigate ambiguity and technical challenges with perseverance
  • TRUST: Collaborate openly, take ownership, and build confidence across teams
  • CANDOR: Give and receive constructive feedback to drive improvement
  • CARE: Show genuine empathy for teammates and customers
  • HUMILITY: Remain curious, acknowledge mistakes, and learn from others
