From cloud infrastructure and data orchestration to performance monitoring and model deployment assistance, you’ll design and scale the systems that make Known fast, reliable, and secure.\nYou’ll work directly with the founding team (AI/ML, product, and design) to establish Known’s technical foundation - shaping not just our architecture, but our engineering culture and best practices from day one. This role is ideal for a pragmatic builder who enjoys going from “blank slate” to production and thrives in early-stage environments where reliability, velocity, and simplicity matter most.\nResponsibilities\nDesign and manage cloud infrastructure (AWS-first, with IaC via Terraform).\n\nEstablish CI/CD pipelines and best practices for rapid, safe iteration (GitHub Actions, Docker, Kubernetes, etc.).\n\nBuild and maintain scalable data ingestion and orchestration pipelines to support ML and product analytics.\n\nAdminister and optimize our databases - PostgreSQL (with pgvector for embeddings) and analytical warehouse.\n\nCollaborate with AI/ML engineers to deploy and monitor LLM and matching models for inference, evaluation, and retraining.\n\nImplement observability (logging, metrics, traces, alerts) across backend services, data jobs, and model endpoints.\n\nDrive reliability and scalability across our web, mobile, and agentic systems - from real-time voice matching to background batch workflows.\n\nCollaborate cross-functionally with product, design, and ML teams to ensure infrastructure aligns with user and business needs.\n\nRequirements\n4+ years of experience in infrastructure, platform, or data engineering (startup or high-growth environments preferred).\n\nStrong proficiency in Python, TypeScript, and scripting (Bash/YAML).\n\nDeep understanding of cloud architecture (AWS, GCP, or similar) and Infrastructure-as-Code (Terraform, Pulumi, or CloudFormation).\n\nSolid experience with containerization and orchestration (Docker, Kubernetes, ECS).\n\nProven ability to design and operate data pipelines and distributed systems.\n\nExperience with PostgreSQL (ideally with pgvector or embeddings), data modeling, and schema design for real-time and analytical workloads.\n\nFamiliarity with ML/AI workflows (model training, inference, monitoring) and feature stores is a plus.\n\nDevOps fundamentals: observability, cost optimization, and security.\n\nCollaborative mindset, strong ownership, and bias toward shipping working systems fast.\n\nExample Projects\nStand up a data lake + warehouse for storing and analyzing user signals, transcripts, and model outputs.\n\nBuild real-time ingestion from app, agent, and third-party APIs (OpenAI, Twilio, Stripe).\n\nDeploy and scale voice agent infrastructure with low-latency streaming, recording, and monitoring.\n\nDesign the CI/CD and observability stack for Known’s core services.\n\nAssist ML engineers in Implementing model deployment pipelines for embedding generation and re-ranking inference.\n\nWhy This Role\nYou’ll help define the technical foundation of a product that blends human connection and advanced AI. As one of Known’s first engineers, you’ll make decisions that influence how the product scales, performs, and evolves - from the data stack to the deployment layer.\nIf you’re excited by the idea of shaping the platform behind a category-defining AI product, this is the place to build it.","description_format":"text","description_chars":3529,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Venture Capital"],"lifecycle":[{"event":"open","at":"2025-10-09T18:57:14Z"},{"event":"reopen","at":"2026-10-14T00:16:54Z"}],"visa":[],"liveness":{"score":15,"band":"cold","label":"Long shot","p_open":1,"p_active":0.544,"p_room":0.28,"age_days":372,"expected_fill_days":173,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/pear-vc-infra-platform-engineer-known","json_url":"https://alion.io/job/pear-vc-infra-platform-engineer-known.json","meta":{"generated_at":"2026-10-17T21:06:14Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":5486,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":6218},"rest":"https://alion.io/mcp/rest/get_company?id=6218"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpear-vc-infra-platform-engineer-known"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fpear-vc-infra-platform-engineer-known"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fpear-vc-infra-platform-engineer-known"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/pear-vc-infra-platform-engineer-known\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpear-vc-infra-platform-engineer-known"}]}
