We believe in the joy of serving others, and that's why we created Otter - to help restaurateurs succeed in online food delivery. Restaurants around the world, both large and small, including Chick-fil-A, Ben & Jerry’s, KFC, and Eataly trust our software to power their delivery business. We increase sales, reduce order issues, and decrease delivery headaches.\nWhat you’ll do\nAt Otter POS, we build the backend that keeps restaurant point-of-sale running: orders, payments, menus, and device state across Android tablets in the kitchen and at the counter. Those services have to stay consistent when WiFi drops mid-service.\nAs a backend engineer on this team, you will design and scale the services behind order orchestration, payment flows, offline-first sync, and multi-device coordination. We want product-minded or systems-focused backend engineers. You do not need prior POS experience. If you like distributed systems, careful API design, and reliability work under real restaurant conditions, you will fit here.\nCore responsibilities\nDesign, build, and maintain Java backend services for order lifecycle, payments, device sync, and restaurant workflows.\nDesign and optimize APIs and event-driven systems so POS devices, kitchen displays, and cloud services stay consistent with low latency.\nBuild systems that keep working offline and sync across multiple devices in a facility.\nWork with Android engineers, product managers, and other teams to ship systems used in live restaurants.\nKeep code quality high through testing, code reviews, observability, and owning what you ship in production.\n\nWhat we’re looking for\nBachelor’s degree in Computer Science or equivalent experience is required.\n3+ years of professional software engineering experience.\nDeep understanding of backend system design, APIs, data stores, microservices, concurrency, and distributed systems.\nOur stack heavily utilizes Java and Kotlin, but we care more about your engineering fundamentals than the specific languages you've used.\nExperience with relational and/or NoSQL databases (e.g., PostgreSQL, CockroachDB, Redis).\nExperience with cloud platforms like AWS, Google Cloud, or Azure.\nPreferred Qualifications\nExperience with event streaming or stream processing (e.g., Kafka, Flink).\nExperience building systems that handle ordering states, payment flows, or multi-device coordination.\nFamiliarity with offline-first architectures, sync protocols, or conflict resolution (CRDTs a plus).\nComfort working with mobile and client engineers, including how backend choices affect reliability on the device.\nInterest in building systems that restaurant operators and staff use every day.\nWhy join us \nDemand for online food delivery is growing really fast! In the last 5 years, just in the US, the overall market has expanded 10X from $10B to $100B, and could expand to $500bn- $1T by 2030.\nChanging the restaurant industry: You’ll be part of a team that helps restaurants succeed in online food delivery. \nCollaborative environment: You will receive support and guidance from experienced colleagues and managers, helping you to learn, grow and achieve your goals, and you’ll work closely with other teams to ensure our customer’s success.\nWhat else you need to know \nThis role is based in our Los Angeles office location. As a company driven by innovation and continuous change, close collaboration is essential. We’re constantly reimagining our industry, creating new products, and refining our processes, and we do our best work together. That’s why all of our office-based teams work onsite, five days a week. \nThe base salary range for this role is$167,000 - $230,000 per year.\nActual compensation will be determined on an individual basis and may vary depending on experience, skills, and qualifications.\nBase salary is just one part of your total rewards package. You may also be eligible for equity awards and an annual performance-based bonus.\nBenefits Summary (USA Full-Time Exempt Employees):\nMedical, dental, and vision insurance (multiple plans, incl. HSA options).\nCompany-paid life and disability insurance (short- and long-term).\nVoluntary insurance: accident, critical illness, hospital indemnity.\nOptional supplemental life insurance for self, spouse, and children.\nPet insurance discount.\n401(k).\nHealth Savings Account (HSA)\nFlexible Spending Accounts (Healthcare, Dependent Care, Commuter)\nTime Off policies:\nDiscretionary vacation days\n8 paid holidays per year\nPaid sick time\nPaid Bereavement leave\nPaid Parental Leave\nBenefits are subject to change at the company's discretion.\nAtoms accepts applications on an ongoing basis.\nReady to join us as we serve those who serve others? \n#LI-Onsite","description_format":"text","description_chars":4908,"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","Life insurance","Parental leave","Vision insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Manufacturing","Robotics","Industrial Automation","Industrial Robotics"],"lifecycle":[{"event":"open","at":"2026-10-01T20:44:01Z"},{"event":"open","at":"2026-10-06T15:59:27Z"}],"visa":[],"liveness":{"score":45,"band":"ok","label":"Likely open","p_open":1,"p_active":0.757,"p_room":0.6,"age_days":57,"expected_fill_days":60,"reasons":["conf:3","velocity","win:late","crowd:brand"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/atoms-senior-backend-software-engineer-2","json_url":"https://alion.io/job/atoms-senior-backend-software-engineer-2.json","meta":{"generated_at":"2026-10-12T05:54:34Z","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":9463,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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":1533},"rest":"https://alion.io/mcp/rest/get_company?id=1533"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fatoms-senior-backend-software-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%2Fatoms-senior-backend-software-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%2Fatoms-senior-backend-software-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/atoms-senior-backend-software-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fatoms-senior-backend-software-engineer-2"}]}
