Our mission is to provide every elementary student with joyful and connected learning experiences that lay the foundation for success in life.\nYOUR TEAM\nYou will join a small, dedicated group of senior engineers assembled specifically for one of Seesaw's most critical technology initiatives. This is not a business-as-usual maintenance assignment: the team has a focused mandate to make consequential improvements to the foundations of our production platform. The group reports directly to our Director of Platforms, who will serve as the team's engineering manager and lead the work day to day. Working closely with experienced Core Platform engineers, you'll have meaningful technical ownership, direct access to engineering leadership, and the opportunity to shape systems that support millions of educators, students, and families. Our emphasis is on thoughtful architecture, hands-on execution, and incremental delivery without compromising security or reliability.\nYOUR ROLE\nWe're looking for a senior backend engineer to evolve and build the internal platform services, especially configuration, that make a sophisticated SaaS product easier to operate and extend. This role calls for a mix of backend architecture, configuration and stateful workflow design, systems integration, and hands-on execution. You'll own technically complex capabilities with wide impact across engineering, spanning build-time configuration, runtime configuration, and customer-managed settings.\nYOUR RESPONSIBILITIES\nDesign and implement scalable backend services, internal APIs, and durable operational workflows.\nEvolve a layered configuration model spanning build-time, runtime, and customer-managed settings, with clear precedence, ownership, and storage, including migrating legacy settings code onto it incrementally.\nBuild and evolve runtime configuration and feature-flag capabilities with safe rollout, validation, auditability, and rollback.\nModel state transitions, configuration, orchestration, and recovery paths for critical platform capabilities.\nDesign clear interfaces between shared platform capabilities and product-facing services, including customer-facing settings and preferences.\nApply sound authentication, authorization, auditability, and secure-by-default engineering practices.\nCollaborate with infrastructure, client, and application teams to deliver production-ready systems with tests, documentation, and observability.\nWHAT WE'RE LOOKING FOR\n8+ years of professional backend engineering experience, including technical ownership of complex platform services; equivalent demonstrated experience considered.\nStrong Python and AWS proficiency and proven experience designing dependable production APIs.\nHands-on experience designing or migrating configuration, feature-flag, or settings systems used across many services or customers.\nExperience building long-running or asynchronous workflows with clear state management and recovery behavior.\nUnderstanding of distributed systems, concurrency, consistency, security boundaries, and operational correctness.\nAbility to simplify ambiguous system requirements into clean interfaces and incremental implementation plans.\nStrong independent delivery, clear communication, and comfort owning consequential work in a small, director-led engineering team.\nNICE TO HAVE\nExperience building internal developer platforms, provisioning services, orchestration engines, or administrative systems.\nExperience with web or mobile build configuration, environment-specific builds, or remote configuration for client apps.\nDeclarative workflows, reconciliation patterns, or event-driven systems.\nTypeScript or lightweight internal tooling experience.\nWHAT SUCCESS LOOKS LIKE\nConfiguration is consistent, auditable, and safe to change across builds, environments, and customers; important platform workflows become repeatable, traceable, and recoverable; and other engineering teams gain dependable interfaces.\nCONTRACT ENGAGEMENT\nThis is a senior, hands-on individual-contributor contract opportunity with a dedicated team led by the Director of Platforms. Engagement duration, location/working arrangement, and commercial terms will be discussed during recruiting.\nA note on language: Our team collaborates daily with US-based colleagues in English, so please submit your resume and application materials in English. We’re unable to review applications submitted in other languages.\nSeesaw values diverse perspectives and welcomes qualified candidates from all backgrounds. We aim to build inclusive teams that reflect the educators, students, and families we serve.\nOur company participates in E-Verify.","description_format":"text","description_chars":4992,"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":[{"language":"English","level":"All levels","optional":true}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Social Networks"],"lifecycle":[{"event":"open","at":"2026-10-20T23:55:14Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":6,"expected_fill_days":50,"reasons":["conf:2","velocity","win:early"],"computed_at":"2026-10-27T05:46:45Z"},"pay":null,"html_url":"https://alion.io/job/seesaw-senior-backend-engineer-platform-services-configuration","json_url":"https://alion.io/job/seesaw-senior-backend-engineer-platform-services-configuration.json","meta":{"generated_at":"2026-10-28T02:58:05Z","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":3967,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"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":41557},"rest":"https://alion.io/mcp/rest/get_company?id=41557"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fseesaw-senior-backend-engineer-platform-services-configuration"},{"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%2Fseesaw-senior-backend-engineer-platform-services-configuration"},{"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%2Fseesaw-senior-backend-engineer-platform-services-configuration"},{"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/seesaw-senior-backend-engineer-platform-services-configuration\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fseesaw-senior-backend-engineer-platform-services-configuration"}]}
