Powered by AI, Treasure AI is shaped by human creativity and always-on through continuous, context-driven action.\nFurthermore, Treasure AI employees are enthusiastic, data-driven, and customer-obsessed. We are a team of drivers-self-starters who take initiative, anticipate needs, and proactively jump in to solve problems. Our actions reflect our values of honesty, reliability, openness, and humility.\nYour Role:\nAs a Senior Software Engineer on the Realtime/Personalization team, you will be a core technical contributor building Treasure AI's AI-native Personalization Studio and RT2.0 engine. Operating at the intersection of deep engineering and product execution, you will help a high-performing squad build mission-critical, realtime personalization and customer journey systems at enterprise scale with deep AI integration.\nIn this role, you will act as a high-impact individual contributor within a squad-based model. While your core expertise may lay in either complex frontends or robust distributed backend systems, you possess the ability to design and implement features across the full stack. You will own significant features end-to-end, collaborating directly with product managers and designers to ship tools that have a tangible impact on our customers' ability to generate value from their data.\nResponsibilities:\nDesign, build, and ship features end-to-end across the Personalization Studio and RT2.0 engine, balancing speed of delivery with long-term maintainability.\n\nDrive feature delivery including scoping, technical design, and negotiation with the Product team to break down complex requirements into executable tasks.\n\nDevelop and evolve backend APIs and distributed services, while also contributing to the structure and consistency of our React applications.\n\nContribute to architectural decisions that span the frontend, backend services, and shared platform components to ensure scalability, observability, and security.\n\nLeverage AI tools (e.g., Treasure Work, Claude Code, Gemini, GitHub Copilot) effectively across the development lifecycle-from design and implementation to debugging, testing, and documentation.\n\nRaise the engineering bar through rigorous code reviews, technical mentorship of mid-level engineers, and improvements to operational excellence.\n\nEnsure production health by joining the on-call rotation, investigating complex performance bottlenecks, and treating production operations as a first-class citizen.\n\nJob Requirements:\n5+ years of professional software engineering experience building, shipping, and operating production applications.\n\nStrong backend proficiency (experience with Ruby, Go, Java, or Kotlin is preferred), including a solid understanding of database design and API scalability.\n\nFrontend capability, with a strong working knowledge of the React ecosystem. You understand how to build modular, testable UI components and can comfortably operate across the stack.\n\nSystems knowledge, including an understanding of distributed systems, microservices architecture, and cloud-native deployment patterns (AWS, GCP, or Azure). Experience handling non-trivial scale or data volume in production is a strong plus.\n\nAI fluency, with a proactive mindset toward adopting AI-assisted development tools to enhance code quality, velocity, and system understanding.\n\nEnd-to-end ownership, with a track record of leading features through scoping, technical design, implementation, rollout, and post-launch support.\n\nBachelor's degree in Computer Science or equivalent practical experience.\n\nPhysical Requirements:\n3 days in our office in a week.\nTravel Requirements:\nSome - May be asked to travel to meet team and stakeholders for offsites.\nOur Dedication to You:\nWe value and promote diversity, equity, inclusion, and belonging in all aspects of our business and at all levels. Success comes from acknowledging, welcoming, and incorporating diverse perspectives.\nDiverse representation alone is not the desired outcome. We also strive to create an inclusive culture that encourages growth, ownership of your role, and achieving innovation in new and unique ways. Your voice will be heard, and we will help amplify it.\nAgencies and Recruiters:\nWe cannot consider your candidate(s) without a contract in place. Any resumes received without having an active agreement will be considered gratis referrals to us. Thank you for your understanding and cooperation!\nThis description captures the core of the role today. As we adopt AI and new ways of working, responsibilities may evolve, and we encourage team members to take initiative, lean into change, and help expand the impact of their role beyond what’s listed here.","description_format":"text","description_chars":4805,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Marketing Automation","Customer Data Platforms (CDP) & Reverse ETL"],"lifecycle":[{"event":"open","at":"2026-09-29T17:54:05Z"}],"visa":[],"liveness":{"score":83,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.832,"p_room":1,"age_days":15,"expected_fill_days":47,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-10-14T06:34:16Z"},"pay":null,"html_url":"https://alion.io/job/treasure-data-senior-software-engineer-realtime-and-personalization-team","json_url":"https://alion.io/job/treasure-data-senior-software-engineer-realtime-and-personalization-team.json","meta":{"generated_at":"2026-10-14T16:04:12Z","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":20418,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":180505},"rest":"https://alion.io/mcp/rest/get_company?id=180505"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftreasure-data-senior-software-engineer-realtime-and-personalization-team"},{"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%2Ftreasure-data-senior-software-engineer-realtime-and-personalization-team"},{"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%2Ftreasure-data-senior-software-engineer-realtime-and-personalization-team"},{"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/treasure-data-senior-software-engineer-realtime-and-personalization-team\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftreasure-data-senior-software-engineer-realtime-and-personalization-team"}]}
