The process today is time intensive, incredibly expensive, and often ends in failure. The Protege platform facilitates the secure, efficient, and privacy-centric exchange of AI training data.\nSolving AI’s data problem is a generational opportunity. We’re backed by world-class investors and already powering partnerships with some of the most ambitious teams in AI. The company that succeeds will be one of the largest in AI - and in tech.\nWe’re a lean, fast-moving, high-trust team of builders who are obsessed with velocity and impact. Our culture is built for people who thrive on ambiguity, own outcomes, and want to shape the future of data and AI.\nAbout the Role\nProtege is hiring a Senior Software Engineer to own the data processing layer at ingestion - the part of the platform that takes large-scale source data and turns it into clean, structured, enriched, validated, AI-ready datasets. This is a hands-on, backend- and data-heavy role with end-to-end ownership of the pipelines that move and process data at volume.\nProtege connects organizations that hold high-value data with the AI builders who need it. The value of that exchange depends on what happens at ingestion: raw, varied, high-volume source data has to be processed reliably, securely, and at scale before it's useful to anyone.\nYou'll work across imaging, audio, video, and other data modalities, crossing healthcare, media, and other disparate industries and data partners. You’ll partner closely with product, Data Lab, and partner engineering teams to build robust ingestion and processing systems for structured and unstructured data at massive scale, from millions to billions of records, files, and other source objects. This role is ideal for engineers who are energized by messy data at scale, want deep ownership of critical infrastructure, and like turning ambiguity into reliable systems.\nWhat You'll Do\nIngestion & Processing Systems\nDesign, build, and operate the ingestion systems that process large volumes of multimodal data into usable, well-structured datasets\n\nOwn the ingestion path end to end, from how data lands to how it is validated, processed, tracked, and made available downstream\n\nBuild modality-specific processing steps for real-world source data, such as medical imaging processing, audio and video metadata extraction, quality validation, and notes processing\n\nBuild parsers, validators, and normalization logic that can systematically handle messy, non-standard, and high-variance source formats\n\nTurn repeated one-off data handling work into reusable processing patterns, internal tooling, and platform capabilities\n\nScale, Performance & Reliability\nBuild for high volume and high throughput, optimizing systems for reliability, cost, and speed\n\nWork across distributed and parallel compute systems to process workloads that do not fit well on a single machine\n\nChoose the right execution model for the workload, including batch processing, distributed execution, and modern compute patterns for unstructured data and inference-heavy processing\n\nDiagnose and resolve bottlenecks across ingestion and processing systems, and keep performance from degrading as volume and modality complexity grow\n\nData Quality, Security & Compliance\nBuild validation and quality checks that catch bad, incomplete, or malformed data before it propagates downstream\n\nHandle sensitive and regulated data, including PHI, with the security and care the domain demands, including de-identification where required\n\nTrack provenance, metadata, and usage constraints through the ingestion path so downstream use remains compliant and auditable\n\nRaise the quality bar for observability, debuggability, and operational reliability across the ingestion layer\n\nCross-Functional Partnership\nPartner with product and Data Lab to support new modalities, new partner requirements, and non-standard source data\n\nWork directly with partner engineering teams when needed to translate source-system realities into robust ingestion and processing design\n\nSurface recurring patterns that are worth standardizing into reusable transforms, validators, and internal tooling\n\nHelp shape how Protege handles new data types as the platform expands into more complex data environments\n\nWhat Success Looks Like\n30 days: Ramp\nGet productive in the codebase and ship your first improvements to existing pipelines\n\nBuild a working map of the ingestion and processing stack, the major data flows, and how we handle each modality\n\nMeet the engineering, product, and Data Lab teams to understand how the function operates across the company\n\n60 days: Take Ownership\nOwn a processing pipeline or modality end to end, from ingestion through delivery of AI-ready output\n\nDevelop depth in how we handle one or two data types at scale\n\nStart raising the bar on data quality, observability, and processing best practices\n\n90 days: Operate Independently\nOwn a significant part of the ingestion and processing layer and lead design on new modalities or scaling challenges\n\nShip reliably with minimal hand-holding, and help unblock others working in the data layer\n\nIdentify at least one leverage opportunity - a reusable transform, tool, or architectural improvement - worth investing in, and drive it\n\nWhat You Bring\nMust Haves\n5+ years building and operating production backend or data systems, with real experience in data processing at scale\n\nHands-on experience designing and running large-scale data pipelines\n\nStrong programming skills in Python\n\nExperience with distributed data processing\n\nStrong proficiency with AWS\n\nComfort with messy, varied, high-volume data and high ambiguity, with a knack for finding patterns in complex environments\n\nAttention to detail without losing speed, and a bias to action\n\nExcited to work on a product built around moving and processing large volumes of data\n\nCurious, tenacious, and proactive\n\nNice to Haves\nExperience processing one or more specific modalities at scale: medical imaging (e.g., DICOM), text, audio or video\n\nBackground working with sensitive or regulated data environments (HIPAA, healthcare compliance, PHI handling)\n\nExperience with streaming systems or workflow orchestration (e.g., Airflow, Dagster)\n\nExperience with GCP and Azure\n\nPrior startup experience as a founding or early engineer\n\nFamiliarity with ML, NLP, or LLM-based systems, including embeddings and fine-tuning\n\nProtege Values\nPass the Loved Ones’ Test\nWe act with integrity and do the right thing - especially when it’s hard and no one is watching.\nAlways Find a Way\nWe are resourceful, resilient builders who solve hard problems and push through obstacles.\nGo Fast and Grow Fast\nVelocity matters. We move with urgency, learn quickly, and continuously improve as individuals and as a company.\nPractice Kindness and Candor\nWe communicate directly and respectfully, building trust through honest feedback and genuine care for one another.\nDeliver Together\nWe win as one team. Collaboration, accountability, and shared ownership drive our success.\nOwn the Outcome. Hone the Craft.\nWe take pride in our work, sweat the details, and continuously raise the bar for excellence.","description_format":"text","description_chars":7274,"description_truncated":false,"requirements":{"experience_years_min":5,"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":["AI Training Data & Annotation","Health Data & Interoperability"],"lifecycle":[{"event":"open","at":"2026-06-03T21:54:55Z"},{"event":"reopen","at":"2026-10-13T04:13:12Z"}],"visa":[],"liveness":{"score":28,"band":"fade","label":"Fading","p_open":1,"p_active":0.783,"p_room":0.36,"age_days":137,"expected_fill_days":70,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-19T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/protege-senior-software-engineer-data-processing","json_url":"https://alion.io/job/protege-senior-software-engineer-data-processing.json","meta":{"generated_at":"2026-10-19T15:12:42Z","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":11149,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-20T00:00:00Z"}},"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":1805974},"rest":"https://alion.io/mcp/rest/get_company?id=1805974"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fprotege-senior-software-engineer-data-processing"},{"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%2Fprotege-senior-software-engineer-data-processing"},{"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%2Fprotege-senior-software-engineer-data-processing"},{"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/protege-senior-software-engineer-data-processing\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fprotege-senior-software-engineer-data-processing"}]}
