We value bright minds and inspire them to grow with their ideas. Come and shape the future of finance with us.\nInternship Project & Portfolio Management and Project Controlling 80-100%\nZurich|80-100%| Reference8378\nSIX runs the infrastructure behind the Swiss and Spanish financial markets: exchanges, post-trade, financial information and banking services. Every year, SIX invests a substantial budget in projects that shape that infrastructure. Our team makes sure that money goes to the right places, delivers what was promised, and gives the Executive Board a clear view of the whole portfolio.\nWe are rebuilding how SIX manages its project portfolio. This includes a new framework for allocating investment capital, sharper decision formats for the Executive Board, and new ways to fund fast-moving initiatives such as AI. This is a period of active redesign, not maintenance. You will join a small, senior team in the middle of it. This internship is limited to 6 months.\nWhat you will do\nRun the monthly project controlling close. As closing manager, you coordinate actuals, forecasts and variances across the portfolio, and you challenge the numbers before they reach management.\nBuild the portfolio view for senior management. You prepare reporting, dashboards and briefing material for the Executive Board and its committees. That means turning data from dozens of projects into a few messages a decision-maker can act on.\nWork alongside the Portfolio Manager and project controllers on project reviews: Is the business case still valid? Are budget, scope and timeline realistic? What should leadership know that the status report doesn’t say?\nShape the methodology. You help design and test new templates, decision criteria and governance formats, and you see them used in real investment decisions.Find smarter ways to work. You use data analysis, Excel and modeling, and AI tools to automate reporting and surface insight faster. Good ideas get implemented.\n\nTake on a defined analytical project of your own, for example benchmarking how other FMIs and banks allocate capital, or analyzing what has driven cost and schedule overruns in our portfolio. You present your findings to the team leadership at the end of your internship.\nWhat you bring\nBachelor’s or Master’s student, or recent graduate, in Business Administration, Finance, Economics, Industrial Engineering or a related field, with a strong academic record\nA genuine interest in corporate finance, strategy and how large organizations make investment decisions\nStrong analytical skills: you are comfortable in Excel, can build a clean model, and know that a number without a story is useless\nClear writing and visual thinking: you can compress a complex situation into one slide\nRigor and reliability: You will be handling numbers that management relies on, and you notice when something doesn’t add up.\nInitiative: you suggest improvements rather than waiting to be asked\nFluent in German and English\nPrior experience in consulting, audit, banking or corporate finance is a plus, not a requirement\nIf you have any questions, check out our FAQ page or call Maria Teresa Buchananat +41 58 399 8083.\nFor this vacancy we only accept direct applications.\nDiversity is important to us. Therefore, we are looking to receiving applications regardless of any personal background.","description_format":"text","description_chars":3549,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"German","level":"Advanced (C1)","optional":false},{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Asset Management & Funds","Cybersecurity","Events & Ticketing","Data Providers & Datasets"],"lifecycle":[{"event":"open","at":"2026-10-21T11:58:08Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":7,"expected_fill_days":26,"reasons":["conf:3","velocity","win:early","comp:junior"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/six-internship-project-portfolio-management-and-project-controlling","json_url":"https://alion.io/job/six-internship-project-portfolio-management-and-project-controlling.json","meta":{"generated_at":"2026-10-29T22:00:03Z","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":"assistant_verified","counted_by":"address","units_charged":1,"used_today":4397,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"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":47665},"rest":"https://alion.io/mcp/rest/get_company?id=47665"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsix-internship-project-portfolio-management-and-project-controlling"},{"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%2Fsix-internship-project-portfolio-management-and-project-controlling"},{"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%2Fsix-internship-project-portfolio-management-and-project-controlling"},{"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/six-internship-project-portfolio-management-and-project-controlling\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsix-internship-project-portfolio-management-and-project-controlling"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3000327}},{"tool":"search_jobs","arguments":{"company":"six-group.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3000327},"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.
