We build the platform that household-name brands use to run their own loyalty programs.We write Go and run our own database engine on top of local key-value stores. We keep storage and compute on the same dedicated machines and read straight from mmap’ed pages. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.We write our JavaScript by hand, have zero lines of React, and render HTML server-side like it’s 2005.We’re looking for someone who knows the web platform well and can reason all the way down to CPU caches. You’ve spent years building across different stacks and have opinions about the tradeoffs you made. We’d love to see something you built that you’re proud of, and hear why you built it that way.We pay $200–250k a year, all cash. You’ll need to be available from 9am to noon New York time.Full description and how to apply: https://jobs.bubblehouse.com/principal-engineer/","description_format":"text","description_chars":1071,"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":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Sales & Marketing","Gift Cards & Loyalty Programs","Loyalty Programs"],"lifecycle":[{"event":"open","at":"2026-11-04T20:03:00Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":1,"expected_fill_days":29,"reasons":["seen:1","win:early"],"computed_at":"2026-11-06T05:58:05Z"},"pay":null,"html_url":"https://alion.io/job/bubblehouse-principal-engineer","json_url":"https://alion.io/job/bubblehouse-principal-engineer.json","meta":{"generated_at":"2026-11-06T13:03:51Z","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":23891,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":2288285},"rest":"https://alion.io/mcp/rest/get_company?id=2288285"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fbubblehouse-principal-engineer"},{"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%2Fbubblehouse-principal-engineer"},{"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%2Fbubblehouse-principal-engineer"},{"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/bubblehouse-principal-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fbubblehouse-principal-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3765831}},{"tool":"search_jobs","arguments":{"company":"bubblehouse.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3765831},"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.
