People increasingly discover products and make buying decisions through ChatGPT, Claude, Gemini, and Google's AI Overviews instead of traditional search, and most brands have no idea where they show up in those answers. Peec gives marketing, SEO, and growth teams the data to see exactly that: how visible their brand is across AI platforms, how they compare to competitors, and where to win.\nWe are defining this category, and the market is moving with us. Peec is a Series A company backed by 20VC and Singular, that went from $0 to $15M ARR in 18 months, with a 100+ person team across our Berlin HQ and our New York office.\nAbout the role\nPeec AI is building the data plane for AI visibility: millions of chats, scrapes, citations, sources, model responses, and customer-facing insights running through a fast-moving backend.\nThis role is for an engineer who wants to own the systems behind that. You will not just add endpoints or close tickets. You will make our scraping, chat-processing, source-ingestion, and analytics infrastructure more reliable, cheaper, faster, and easier for the rest of the team to reason about.\nThe best fit looks like someone who can debug a provider outage in the morning, design a better queueing model before lunch, ship a TypeScript service change in the afternoon, and write the postmortem or follow-up ticket clearly enough that the next engineer immediately knows what to do.\nWe are especially interested in people who have built or operated systems with real constraints: rate limits, flaky third-party APIs, queues, webhooks, retries, distributed locks, data migrations, observability gaps, customer pressure, and cost ceilings.\nWhat we’re looking for\n5+ years of backend, platform, infrastructure, or distributed systems engineering experience in a production environment.\n\nDeep hands-on TypeScript experience. We run TypeScript services on Bun, and we care about people who can design clean, reliable backend systems rather than only write application code.\n\nStrong understanding of queues, workers, retries, rate limits, idempotency, distributed locks, webhooks, and failure handling.\n\nExperience operating systems under real production pressure: incidents, provider outages, customer escalations, noisy alerts, slow dependencies, and incomplete data.\n\nComfort with cloud-native infrastructure. Our stack includes GCP, Kubernetes, Cloud Tasks, Pub/Sub, RabbitMQ, Redis, Postgres, Firestore, ClickHouse, Prometheus, Grafana, and OpenTelemetry.\n\nAbility to debug across layers: application code, logs, metrics, queues, provider APIs, databases, network behaviour, and deployment state.\n\nProduct-minded judgement. You can separate internal detail from customer-safe explanation, and you understand when a “small infra change” has customer, security, or cost implications.\n\nHigh ownership and low ego. We want people who take responsibility for ambiguous systems, ask sharp questions, and make the team better through clear thinking and kindness.\n\nA bias toward durable fixes. You do not stop at “restart the pod” if the real issue is retry amplification, missing backpressure, an unsafe parser assumption, or a provider limit we do not model.\n\nTech stack\nLanguages: TypeScript, Python\n\nRuntime/frameworks: Bun, Elysia, Node-compatible services\n\nCloud/infrastructure: GCP, Kubernetes, Cloud Tasks, Pub/Sub, Firebase/Firestore, Postgres, ClickHouse, Redis, RabbitMQ\n\nObservability: Prometheus, Grafana, OpenTelemetry, structured logging\n\nProduct/data domain: LLM chats, AI search, source scraping, citation extraction, provider integrations, customer-facing analytics\n\nAI/model providers: OpenAI, Anthropic/Claude, Perplexity, Gemini, Google AI Mode / AI Overview, plus scraping/provider APIs around them\n\nWhat we offer\nExciting and challenging work with real impact and ownership at one of Europe’s fastest-growing Series A startups\n\nRegular team events and off-sites\n\nAggressive equity compensation package\n\nPaid Dinner & Uber home when working late\n\nThe most beautiful office space and work environment in Berlin","description_format":"text","description_chars":4119,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Search Engine Optimization (SEO)","Marketing & Sales AI","Social Media Analytics & Listening"],"lifecycle":[{"event":"open","at":"2026-09-05T18:45:29Z"}],"visa":[],"liveness":{"score":19,"band":"cold","label":"Long shot","p_open":1,"p_active":0.43,"p_room":0.45,"age_days":56,"expected_fill_days":31,"reasons":["conf:0","stale_co","win:tail"],"computed_at":"2026-10-30T05:48:23Z"},"pay":{"stated_usd_annual":168377,"is_top_pay":false},"html_url":"https://alion.io/job/peec-ai-senior-backend-engineer-2","json_url":"https://alion.io/job/peec-ai-senior-backend-engineer-2.json","meta":{"generated_at":"2026-10-31T02:58:50Z","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":4214,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":63602},"rest":"https://alion.io/mcp/rest/get_company?id=63602"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpeec-ai-senior-backend-engineer-2"},{"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%2Fpeec-ai-senior-backend-engineer-2"},{"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%2Fpeec-ai-senior-backend-engineer-2"},{"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/peec-ai-senior-backend-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpeec-ai-senior-backend-engineer-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":348159}},{"tool":"search_jobs","arguments":{"company":"peec.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":348159},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
