We use the best cloud-native and AI-enabled tools, and apply a battle-tested combination of Agile, Lean, and design thinking to collaboratively solve our client’s most pressing challenges - and do it right the first time. We often work in regulated industries, such as healthcare, financial services, government and education. Our work helps detect diseases, identify kids who need special educational support, applies AI to support complex legal settlements, helps people access mental health services, and so much more.\nAbout the Role\nWe are seeking an experienced, highly motivated Senior Full-Stack Engineer to join our growing team. The ideal candidate will be a strong collaborator with deep expertise in modern application development technologies and practices. The focus of this role is on building and maintaining robust, scalable, and high-performance applications across the full stack using TypeScript and some Python. Some experience with React and/or Angular would be helpful.\nThis role requires not only technical proficiency but also a forward-thinking perspective on the role of Artificial Intelligence (AI) in modern software development. Candidates must demonstrate an active engagement with AI tools, understanding their practical use, current limitations, and the strategic opportunities they present for the engineering discipline.\nMainly remote work: seeking candidates in the greater Los Angeles area to mainly work remotely with some on-site work required at times.\nKey Responsibilities\nLead the design, development, and deployment of complex features across both the frontend and backend of our clients’ products.\nWrite clean, maintainable, and well-tested code using TypeScript for type safety and scalability on both the client and server.\nCollaborate with product managers, designers, and other engineers to translate business requirements into technical solutions.\nCollaborate with other team members to set technical standards, establish best practices, and make architecture decisions.\nActively research and evaluate new technologies, tools, and methodologies to improve the engineering process.\n Demonstrate and articulate a practical understanding of AI tools (e.g., planning, code generation, intelligent testing frameworks) in daily engineering tasks, including their effective application and inherent limitations.\nQualifications\n5+ years of experience in full-stack software development.\nExpert-level proficiency with TypeScript, including complex type definitions and advanced language features.\n Strong experience with server-side development, including building and consuming RESTful APIs or GraphQL services (proficiency with Hono Framework is a plus).\nProficiency with relational and non-relational databases\n Familiarity with modern CI/CD pipelines, containerization (Docker), and cloud platforms (primarily AWS, with experience in GCP and/or Azure a plus).\n Preferred, but not required: Proficiency with React and its ecosystem (e.g., Hooks, Context API, Next.js, or similar frameworks). Experience with Angular (any version) in a professional capacity is a plus.\nAI and the Evolution of Software Engineering & Ops\nAll candidates must be prepared to discuss and demonstrate the following during the interview process:\nPractical AI Tool Usage: Specific examples of AI tools used in professional or personal projects to enhance productivity, solve complex problems, or accelerate development. If you have a preferred agentic tool setup, please share!\nUnderstanding of AI Limitations: A clear understanding and articulation of the current technical, ethical, and accuracy limitations of modern AI tools in the engineering context.\nStrategic AI Opportunity: A viewpoint on how AI tools create new opportunities for software engineering, such as shifting focus from boilerplate code to complex problem-solving or architectural design.\n Evolution of the Engineering Role: A well-articulated point of view on how your role has already changed (e.g., new workflows, skills, ways of collaborating) due to the introduction of AI and how you expect the role to evolve in the coming years based on your assessment of coming advancements in AI tools and technologies.\nSalary Range $135,000 - $175,000\nApplication Process\nA cover letter is required. Your cover letter should be informed by the “AI and Forward-Looking Requirements” section above.\nThe hiring process includes:\nInitial Screening Call\nA Technical Assessment sent by email and returned by email\nA Panel Interview\nBenefits for Full-Time Employees\nExcellent health, dental, vision, and life insurance\nExcellent 401(k) plan with annual employer match of 4%","description_format":"text","description_chars":4802,"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":["Life insurance"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Consulting & Digital Transformation","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-09-11T18:11:41Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.266,"p_room":0.28,"age_days":96,"expected_fill_days":31,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-13T05:45:00Z"},"pay":{"stated_usd_annual":175000,"is_top_pay":false},"html_url":"https://alion.io/job/vynyl-senior-full-stack-engineer-typescript","json_url":"https://alion.io/job/vynyl-senior-full-stack-engineer-typescript.json","meta":{"generated_at":"2026-10-13T09:38:32Z","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":14632,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":686281},"rest":"https://alion.io/mcp/rest/get_company?id=686281"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvynyl-senior-full-stack-engineer-typescript"},{"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%2Fvynyl-senior-full-stack-engineer-typescript"},{"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%2Fvynyl-senior-full-stack-engineer-typescript"},{"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/vynyl-senior-full-stack-engineer-typescript\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvynyl-senior-full-stack-engineer-typescript"}]}
