Clay's mission is to be the engine those companies use to grow to their full potential.\nClay predicts the next best action for your business and then helps you take it. We started by aggregating the best data for B2B companies. Then, we built the infrastructure to run any personalized campaign on top of it, including emails, ads, landing pages, and workflows that make reps more productive. Now, we're building agents that can help grow your company for you. We're already helping thousands of customers - including Anthropic, OpenAI, Google, and Visa - go to market with unique data, signals, and AI research.\nIn 2026, we raised a $115M Series D at $7.1B Valuation led by Wellington - and are on track to cross $200M in revenue this quarter. We also launched a $1M Scholarship fund for GTME Education.\nSome things to know about us:\nOur community includes 17,000+ customers, 200+ integration partners, 125+ agencies, 50+ Clay clubs, and 30k members on Slack.\n\nOur culture is unique inside and outside of work. Our team members are also DJs, activists, writers, clowns, marathoners, skydivers, psychedelic therapists, social workers, and more.\n\nAll employees can work with world-class coaches who specialize in creativity, management, and more.\n\nOur operating principles - including negative maintenance and non-attached action - guide our work. Read more about them here.\n\nRead about us in the NYT, Forbes, First Round Review, and more.\n\nHear from our employees directly on our Glassdoor page!\nThe Role\nAs a Software Engineer on one of our Infrastructure or Platform teams, you'll work on the systems every Clay product depends on: how work gets executed and scheduled at scale, how services hold up under concurrency, how data is stored and served with predictable latency, and how the shared foundations are built so that product teams extend them rather than route around them.\nThis is a role with real latitude, the Platform work at Clay is not a back-office function. Whether a product team can ship next quarter usually comes down to whether the foundation supports it, and you'll be one of the people deciding what that foundation looks like.\nWhat You'll Work On\nScale, reliability, and performance. Address DB contention, memory pressure, throughput ceilings, and any other bottlenecks that arise. Set performance and reliability targets that hold as we scale.\n\nPlatforms other engineers build on. Define the primitives, contracts, and extension points that let product teams ship on shared infrastructure.\n\nExecution and orchestration. Evolve how work is defined, scheduled, retried, and observed across the product.\n\nObservability. Give customers and engineers the instrumentation to see what a run did, where it went wrong, and why.\n\nRaise the bar around you. Set technical direction other teams inherit, and pull engineering standards up through design reviews, code review, and the systems you leave behind.\n\nWhat Success Looks Like\nProduct teams ship on shared infrastructure without needing a platform engineer to hold their hand.\n\nThe system stays predictable as load grows 10x, and cost per unit of work goes down rather than up.\n\nLarge, complex, long-running jobs are boring: they complete, and when they don't, the reason is obvious.\n\nWe can change how a core system works without breaking the products built on it.\n\nScale and reliability decisions are made against measured evidence.\n\nWhat You'll Bring\n8+ years of hands-on experience building and operating production systems at scale.\n\nYou spike hard on at least one of:\nScale, reliability, and performance - you've diagnosed and fixed DB contention, memory blowups, and throughput ceilings on systems under real load.\n\nPlatform and frameworks - you've built internal-facing platforms that other engineers built products on.\n\nYou think about platforms as products. You know who your consumers are, you design for their success, and you treat a confusing abstraction as a bug.\n\nYou're comfortable reasoning about distributed systems, concurrency, queuing, backpressure, and failure recovery, and about the data models underneath them.\n\nYou write and communicate clearly. Your design docs and RFCs make tradeoffs legible and move alignment forward.\n\nYou're familiar with our current tech stack or can learn quickly: React, TypeScript, Python, Node.js; AWS (Aurora/Postgres, Elasticache/Redis, ECR, ECS/Fargate, Lambda, OpenSearch); Terraform; CircleCI, Netlify, Playwright; CloudWatch, Datadog, Mezmo; ClickHouse, Dagster.\n\nNice To Haves\nExperience with workflow engines, orchestration systems, or durable execution frameworks.\n\nExperience taking a system from internal tool to company-wide platform, including migrating existing consumers onto it.\n\nExperience with multi-tenant systems.\n\nExperience running LLM calls or agent loops inside a production execution path.\n\nExperience with data-intensive systems: search infrastructure, large result sets, or high-volume ingestion.\n\nHow We Work\nWe're a cross-site engineering org split between NYC and SF, working in two-week sprints with async planning in Slack, weekly cross-functional team meetings, and Linear as the source of truth for everything we're building.","description_format":"text","description_chars":5262,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Sales Enablement","Lead Generation","Marketing & Sales AI","B2B Company & Contact Data"],"lifecycle":[{"event":"open","at":"2026-08-14T22:29:03Z"}],"visa":[],"liveness":{"score":52,"band":"ok","label":"Likely open","p_open":1,"p_active":0.861,"p_room":0.6,"age_days":62,"expected_fill_days":75,"reasons":["conf:0","velocity","win:late","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":300000,"is_top_pay":true},"html_url":"https://alion.io/job/clay-software-engineer-backend-infrastructure-platform","json_url":"https://alion.io/job/clay-software-engineer-backend-infrastructure-platform.json","meta":{"generated_at":"2026-10-16T19:25:21Z","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":4919,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":1484},"rest":"https://alion.io/mcp/rest/get_company?id=1484"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fclay-software-engineer-backend-infrastructure-platform"},{"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%2Fclay-software-engineer-backend-infrastructure-platform"},{"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%2Fclay-software-engineer-backend-infrastructure-platform"},{"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/clay-software-engineer-backend-infrastructure-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fclay-software-engineer-backend-infrastructure-platform"}]}
