We forecast exactly how much of each product will sell, helping grocery retailers order and produce the perfect amount of inventory - and we're building AI-native tools that put those forecasts directly into the hands of store operators and buyers.\nThe grocery industry is enormous (it accounts for 4% of GDP) - and grocery food waste is a huge cost to grocers' bottom lines, but also to our planet.\nToday, we're working with major supermarket chains in the US and Canada, and we've scaled to 7-figures in ARR. We're backed by leading investors including Y Combinator, 1984 Ventures, Collaborative Fund, and angels from Open AI, Instacart, and Citadel Securities.\nWe've brought together an exceptional team from Palantir, BCG, Oxford, Cambridge, and MIT to solve intellectually challenging problems and tackle food insecurity and waste with technology.\nWe're looking for talented engineers in NYC to join our mission.\nAbout the Role\nAs a Backend Engineer at Guac, you'll have real impact and ownership over technical decisions, strategy, and product direction. Your responsibilities will include:\nDesign and build robust backend services that power mission-critical ordering and production planning products\nBuild efficient ETL pipelines to handle billions of rows of data, multiple times per day\nBuild AI-powered tools and agents for internal and customer use - exposing our data and forecasting systems via MCP servers, tool-use APIs, and similar protocols so that LLMs can reason over and act on grocery operations data\nCollaborate directly with customers' technical teams to understand and integrate with their IT infrastructure\nHelp define how we leverage LLMs across the product surface, from agentic workflows to natural-language interfaces over our forecasts\nAbout You\n3+ years of relevant software engineering experience\nStrong proficiency in Python and associated frameworks (FastAPI or similar)\nAI-native: you use Claude Code, Cursor, or similar AI coding tools daily and ship significantly faster because of it\nHands-on experience building with LLMs - tool use / function calling, RAG, agents, or evals - and familiarity with MCP or similar protocols for connecting models to data and systems\nExperience designing and operating data-intensive backend systems (ETL, large-scale pipelines, distributed processing)\n(Bonus) Experience in customer-facing technical roles (e.g. forward deployed engineer)\n(Bonus) Experience deploying LLM-powered features to production at scale\nWhat We Offer\nFirst-hand experience building an early-stage startup\nCompensation: $150k-$250k base + competitive equity\nFully employer-paid healthcare (medical, dental, and vision)\nUnlimited vacation days\nFully covered food expenses in the office (lunch/dinner)\nFree Equinox membership\nOur Tech Stack\nLanguages & Frameworks: Python, FastAPI, Dagster, Dask\nCloud & Infrastructure: GCP, Postgres, BigQuery, Terraform, Docker\nAI: MCP servers, Anthropic/OpenAI APIs, agentic tooling\nNote: this is an in-person 5 days a week, full time job in NYC.","description_format":"text","description_chars":3077,"description_truncated":false,"requirements":{"experience_years_min":3,"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":["Agriculture AI","Supply Chain AI"],"lifecycle":[{"event":"open","at":"2026-09-07T19:44:01Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"Filed H-1B visas in the last two years","filings_12m":0,"filings_prev_12m":1,"green_card_filings_12m":0,"median_offered_wage_usd":null,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":17,"band":"cold","label":"Long shot","p_open":1,"p_active":0.496,"p_room":0.35,"age_days":46,"expected_fill_days":23,"reasons":["conf:2","win:tail"],"computed_at":"2026-10-24T06:02:35Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/guac-backend-engineer","json_url":"https://alion.io/job/guac-backend-engineer.json","meta":{"generated_at":"2026-10-24T21:14:20Z","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":31121,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":9236},"rest":"https://alion.io/mcp/rest/get_company?id=9236"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fguac-backend-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%2Fguac-backend-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%2Fguac-backend-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/guac-backend-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fguac-backend-engineer"}]}
