Influence how we build it. Help modernize a product area at the heart of construction projects.\n\nDalux is growing, and we are looking for an experienced software developer to join our Box Collab team.\n\nYou will build software in our File Management product (Box) that enables communication and collaboration across construction stakeholders—for example, file comments, sharing, versioning, and review. This domain is widely used and deeply integrated across the Dalux product suite, so reliability, performance, and strong technical design are essential. In Box Collab, we foster an engaging, enjoyable work environment where people take ownership and accountability for outcomes. You’ll join a young, skilled team with strong opportunities to influence both product evolution and architectural direction.\n\n**Your role\n\n**As an Experienced Software Developer, you will take ownership of complex product and technical problems from idea to production.\n\nYou will join a full-stack development team working closely with a Product Manager and Product Designer. We expect experienced developers to contribute beyond their individual tasks: helping make good technical decisions, improving the codebase and architecture, sharing knowledge, and raising the engineering standard around them.\n\nWithin Box Collab, there is a particular focus on strengthening and evolving the technical foundation of the product while continuing to deliver new functionality.\n\nYour work can include:\n\nOwning complex features and technical problems end-to-end\n\nDesigning and implementing scalable, maintainable solutions\n\nContributing to architectural decisions and the technical direction of Box Collab.\n\nImproving the structure of an established codebase and reducing technical debt\n\nHelping evolve boundaries and modularity within the application\n\nSparring with and mentoring other developers\n\nWorking closely with Product Management and Design to understand problems and find the right solutions\n\nBringing new ideas, technologies, and development practices into the team when they create real value\n\nWe expect experienced developers to have opinions, challenge existing solutions, and be comfortable having their own ideas challenged in return.\n\n**AI-assisted software development\n\n**We are significantly increasing our focus on AI-assisted development across Dalux.\n\nWe are actively exploring how AI can improve the software development lifecycle – from understanding requirements and exploring technical approaches to coding, testing, review, debugging, refactoring, and automation.\n\nThe Box Collab team is already experimenting with how these tools can improve its day-to-day development work.\n\nAs an experienced developer, we want you to take an active role in that development: experimenting with new workflows, critically evaluating their value, sharing what works, and helping establish good engineering practices around AI-assisted development.\n\nPractical experience using AI as part of your development workflow is an advantage. More importantly, you should be curious about how these tools are changing software engineering and willing to continue evolving your own way of working.\n\n**Technologies we work with\n\n**Box Collab is a full-stack product area primarily built with:\n\nC# / .NET\n\nAngular / TypeScript\n\nMSSQL\n\nElasticsearch\n\nOur wider platform runs on a distributed cloud architecture using AWS.\n\nExperience with our exact technology stack is useful, but strong software engineering fundamentals and the ability to understand and improve complex systems matter more.\n\n**What would make you a particularly strong match?\n\n**We are looking for an experienced software developer with strong technical fundamentals and the ability to influence the software around you.\n\nFor this particular team, we would especially value:\n\nStr ong professional experience with C# and .NET\n\nStrong DB management experience, including indexing strategies and query performance optimization.\n\nExperience improving or modernizing established software systems\n\nAn understanding of Domain-Driven Design, modular architecture, or similar approaches to structuring complex applications\n\nExperience mentoring or providing technical sparring to other developers\n\nPractical experience with AI-assisted development tools and workflows\n\nYou do not need to match every point.\n\nTechnical judgment, curiosity, and the ability to make an established product better are more important than having worked with exactly the same technologies or architectural patterns before.\n\n**Product development at Dalux\n\n**Our product teams bring developers, Product Managers, and Product Designers together.\n\nDevelopers are expected to understand the problem being solved and contribute to finding the solution – not simply implement specifications handed to them.\n\nAs an experienced developer, you will have an important voice in balancing user value, usability, technical feasibility, business viability, and long-term technical health.\n\nOur products are relied upon by professionals worldwide, making performance, stability, maintainability, and quality important parts of everyday engineering.\n\n**What You Can Expect From Dalux\n\n**Dalux is a software company at heart.\n\nAs an experienced developer, you can expect:\n\nSignificant ownership of the software you build\n\nReal influence on technical solutions and engineering practices\n\nSkilled colleagues who enjoy technical discussion and constructive challenge\n\nClose collaboration between Engineering, Product Management, and Design\n\nShort paths from technical ideas to decisions and implementation\n\nOpportunities to improve an established product and architecture\n\nA healthy work-life balance, with a strong focus on a sustainable work week and no overwork culture.\n\nClear opportunities for professional and career growth.\n\nAn environment actively investing in AI-assisted software development\n\nHigh levels of trust and freedom in how you solve problems\n\nA social workplace with monthly events and employee-driven clubs\n\nAll Dalux software development takes place in-house at our headquarters in Vibenshuset, Copenhagen. Working together in person is an important part of how we collaborate, share knowledge, and make decisions quickly.\n\n**About Dalux\n\n**Dalux is a Danish software company founded in 2005 by Bent Dalgaard and Torben Dalgaard.\n\nWe build digital tools that make the construction industry smarter and more efficient. Using our own 3D BIM technology, Dalux develops user-friendly software used in more than 140 countries worldwide.\n\nOur core technology is developed entirely in-house, giving our developers the opportunity to influence both the products and the technology behind them.\n\n**Interested?\n\n**If you are looking for a role where you can remain hands-on while gaining greater technical influence and helping evolve an established product and architecture, we would like to hear from you.\n\nWe recruit continuously as Dalux grows.\n\n**Application deadline:\n\n**Ongoing","description_format":"text","description_chars":7005,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["CAD, PLM & BIM Software","Construction","Construction Management Software"],"lifecycle":[{"event":"open","at":"2026-11-13T02:52:00Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":1,"expected_fill_days":11,"reasons":["seen:1","win:early"],"computed_at":"2026-11-13T08:05:56Z"},"pay":null,"html_url":"https://alion.io/job/dalux-experienced-software-developer-team-box-collab","json_url":"https://alion.io/job/dalux-experienced-software-developer-team-box-collab.json","meta":{"generated_at":"2026-11-13T08:05:56Z","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":16763,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":55318},"rest":"https://alion.io/mcp/rest/get_company?id=55318"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fdalux-experienced-software-developer-team-box-collab"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fdalux-experienced-software-developer-team-box-collab"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fdalux-experienced-software-developer-team-box-collab"},{"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/dalux-experienced-software-developer-team-box-collab\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fdalux-experienced-software-developer-team-box-collab"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4216275}},{"tool":"search_jobs","arguments":{"company":"dalux.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4216275},"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.
