You'll design systems, write code, prototype ideas, debug the failures nobody else can reproduce, review the implementations that matter, and work alongside engineers and Tech Leads wherever deeper expertise is needed.\nYour influence here won't come from managing people. It comes from the systems you improve, the technical decisions you shape, and the engineers who get better for having worked with you.\nAI is part of the job\nWe're building an AI-first engineering organization, and we want to get further than AI-assisted coding. You'll work with LLMs, AI APIs, agents, RAG, and evaluation, applied to problems in our own engineering and in the products we build for clients.\nWe're not trying to put AI into everything. We want to find the places where it pays off, build those properly, and write down what we learn so other teams can pick it up.\nWhat this role is really about\nOwn architecture and design decisions on the hardest systems in our portfolio\nWrite code, prototype, and debug alongside the teams rather than from a distance\nReview the implementations that carry the most risk, and raise the bar through the work itself\nFind where AI pays off, build it properly, and turn what works into something other teams can reuse\nWork with Tech Leads on scalability, performance, reliability, and technical debt\nEvaluate new technology, prototype it, make a call, and write down the reasoning\nWork with clients and non-engineering stakeholders to turn vague problems into technical direction\nWhat we're looking for\n10+ years building and running production software, and still writing code today\nDepth in system design and architecture: scalability, performance, distributed systems, reliability\nA track record of setting technical direction across several teams, or on one large and long-running program\nQuick to find your way around an unfamiliar codebase. Deep in at least one language and comfortable in several\nTech stack (not strictly limited to): Python, Go, Node.js, Java, Cloud Native (AWS/GCP), Docker/Kubernetes...\nHands-on experience with LLM-based systems. Things you have built, not only read about: AI APIs, prompt and context design, and at least one of agents, RAG, or evaluation\nJudgment about when not to build something, when to pay down debt, and when to say no\nThe ability to mentor senior engineers and change their minds without formal authority\nComfort working directly with clients and non-engineering stakeholders\nA habit of following where the field is going\nNice to have\nProduction AI systems at scale: evaluation harnesses, guardrails, cost and latency tuning\nDepth in one of our domains: data platforms, cybersecurity, robotics, enterprise systems\nInternal tooling or platform work that made other teams faster\nOpen source contributions, conference talks, or technical writing\nWhy Gradion\nou’d be joining Vietnam’s Best IT Company, recognized by ITViec for 8 consecutive years, including 2 successive years as the Winner.\nThat reputation didn’t happen overnight. It’s built on 23 years of shipping real digital platforms and Deep Tech solutions for 100+ enterprise clients, backed by more than 300 specialists across 7 countries.\nFrom AI and data to cybersecurity, robotics, and enterprise platforms, the work here gives you something a single-product environment rarely can: a much wider technical surface area.\nDifferent systems. Different industries. Different problems worth going deep on.\nIf you want Principal Engineer scope without stepping away from engineering, let’s talk.\nWhy You’ll Love Working Here\n - Gradion Vietnam (formerly NFQ Vietnam) has been recognized by ITViec for 8 consecutive years, including 2 successive years as the Winner.\n - Collaborate with engineers, technical leaders, and clients across global markets.\n - Experiment with AI-native engineering, emerging technologies, and real-world AI applications - not just demos.\n - No unnecessary bureaucracy. We care about the quality of your thinking and the impact of your work.\n - Attractive salary, performance-based bonus, and benefits that reflect your impact.\n - Up to 2 months’ performance bonus, twice-yearly performance reviews, premium healthcare, 15 days annual leave, full salary during probation, hybrid working, tech communities, global projects, and continuous learning opportunities.\nWorking time: Monday - Friday, 9 AM - 6 PM\nLocations: Ho Chi Minh City · Da Nang · Remote from Hanoi or Can Tho\nData protection\nAccording to General Data Protection Regulation (GDPR), Singapore's Personal Data Protection Act (PDPA), and Vietnam's Decree 13/2023/ND-CP, while also ensuring compliance with other applicable local data protection laws in the jurisdictions where we operate, including but not limited to Vietnam, Thailand, Egypt, Singapore, Germany, and Saudi Arabia, Gradion applies the “Personal Data Protection Policy” to all candidates to ensure compliance with the laws.\nBy submitting your application to Gradion, you agree to allow us to process your provided information in accordance with the Personal Data Protection Policy that you have carefully read, understood, and agreed to in its entirety at Link.","description_format":"text","description_chars":5517,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual leave","Continuous learning","Hybrid work"],"hiring_locations":[{"name":"Vietnam","iso":"VN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Information Technology","Software","IT Outsourcing & Dedicated Teams","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-09-11T08:27:04Z"}],"visa":[],"liveness":{"score":24,"band":"cold","label":"Long shot","p_open":1,"p_active":0.676,"p_room":0.36,"age_days":125,"expected_fill_days":76,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/gradion-principal-software-engineer","json_url":"https://alion.io/job/gradion-principal-software-engineer.json","meta":{"generated_at":"2026-10-31T02:10:39Z","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":2989,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":673568},"rest":"https://alion.io/mcp/rest/get_company?id=673568"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fgradion-principal-software-engineer"},{"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%2Fgradion-principal-software-engineer"},{"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%2Fgradion-principal-software-engineer"},{"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/gradion-principal-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgradion-principal-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":726189}},{"tool":"search_jobs","arguments":{"company":"gradion.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":726189},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
