Companies use Crossbeam to securely compare CRM data with partners, revealing shared customers, overlapping prospects, and warm paths into deals.\nThat second-party data becomes Ecosystem Intelligence - a layer of unique signals and recommendations that helps revenue teams uncover new opportunities, target the right accounts, and win faster. We pioneered the category of ecosystem-led growth, and now we're defining what comes next: go-to-market powered by AI-native ecosystem intelligence.\nAbout Crossbeam Ventures\nBeyond our core platform, Crossbeam incubates new products built from scratch by small, autonomous teams operating like early-stage startups inside the company. These ventures move fast, ship daily, and are built AI-native from day one. Two products are currently in active development:\nPace is an AI sales performance platform. It connects to CRMs (Salesforce, HubSpot), email, Slack, and call recording tools to give sales teams AI agents that assess deal health, evaluate forecasts, draft personalized emails, and automate daily workflows - turning scattered go-to-market data into decisions and actions.\n\nTrace is a company intelligence platform that maps what any company runs (tech stack), who they partner with, and who they're hiring - built natively for AI agents and modern go-to-market teams, accessible via API, MCP, and a web app.\n\nYou'll join the Ventures team and contribute to one of these products - Pace or Trace - depending on where your skills and our needs align best.\nAbout the Role\nAs a Software Engineer Intern, you'll work directly with the founding team of Pace and Trace and own real features end to end - from design to production. You'll build AI agents, integrations, and product features that ship to real users within days. You'll get a rare inside view of what building a product from zero looks like, with the resources and ambition of a scaling company behind you.\nStart date: September 7th, 2026 (flexible) - 6 months internship\nWhat you'll do:\nDesign and ship product features across the stack (Python, FastAPI, Langgraph, PostgreSQL, Temporal, Pinecone)\n\nBuild and improve AI agents powered by Claude and LangGraph - reasoning over messy real-world data to produce useful, reliable output\n\nDevelop integrations with the tools sales teams live in: Salesforce, HubSpot, Gmail, Slack, and call recording platforms like Gong\n\nUse AI tools (Claude Code and others) every day to amplify what you can build and how fast you can ship\n\nTake part in product discussions: you'll have a real voice in what we build and why\n\nWhat you'll need:\nSolid programming fundamentals, ideally in Python (TypeScript or another language is fine if you learn fast)\n\nGenuine curiosity about LLMs and AI agents - you've built something with them, even a side project\n\nFinal-year student or second half of a gap year\n\nFluency in English (French is a plus); based in Paris and able to work from our Paris office\n\nYou'll do great if you:\nTake ownership without waiting for permission.\n\nAsk \"what's actually needed?\" instead of defaulting to precedent.\n\nUse AI as leverage to clarify thinking, improve communication, synthesize information, and accelerate execution.\n\nActively seek out and act on feedback to raise your own bar.\n\nDig until you understand the real problem, not just the surface request.\n\nMake those around you more effective.\n\nHiring process:\nThe journey starts with a first interview with the HR Generalist (30 min)\n\nThen a conversation with Antoine, your future manager, to dive into the role, the team, and your experience (30 min)\n\nThis will be followed by a take-home case study to assess your practical skills\n\nFinally, a debrief of your case study with the team (1 hour)\n\nOur Core Values\nValues are a social contract that we have with our team, our users, and our communities. They are guiding lights as well as argument-enders, and we expect results delivered in a way that is consistent with these values.\nTrust is our Foundation\nWe create value by building trust in our company, our team, and our technology. That goes in all directions, not just between us and our customers but also amongst ourselves. We approach conflict with empathy and curiosity, and ascribe best intentions to all of our collaborators.\nWork Hard and Smart\nThis is a startup, and we will act like one. We prioritize impact, take personal ownership of outcomes, act decisively, and get our hands dirty in the process. We communicate clearly, avoid over-engineering, and take risks. This allows us to be creative, innovative, and solution-oriented.\nDefault to Transparency\nWe will not succeed in information silos. We share the good, bad, and ugly about what is happening in our company, which requires us to pay attention, always measure what matters, and hold each other accountable.\nBelonging\nIn our workplaces, communities, and ecosystems, we shape environments where people feel a sense of belonging. To do this, we work to ensure that stakeholders of all backgrounds are treated equitably and experience psychological and physical safety. This is key to their relationship with our company, their access to opportunities, and their ability to thrive.\nTreasure the Fun\nWe are incredibly lucky to be here - let's make memories. We will all spend that extra bit of time and energy to energize each other with fun and inspiring experiences. This applies internally and externally, from the smallest interactions to the largest events.\nCrossbeam's core value of Equity sits at the heart of our hiring process, and we're proud to be building a culture where difference is valued. Applicants from diverse and non-traditional backgrounds are strongly encouraged to apply. We recruit, employ, train, compensate and promote regardless of race, religion, color, national origin, sex, sexual orientation, gender, disability, age, or veteran status.","description_format":"text","description_chars":6112,"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":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Lead Generation","B2B Company & Contact Data"],"lifecycle":[{"event":"open","at":"2026-09-06T12:26:35Z"}],"visa":[],"liveness":{"score":15,"band":"cold","label":"Long shot","p_open":1,"p_active":0.418,"p_room":0.36,"age_days":54,"expected_fill_days":32,"reasons":["conf:3","win:tail","crowd:junior"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/crossbeam-software-engineer-intern-crossbeam-ventures-mfx","json_url":"https://alion.io/job/crossbeam-software-engineer-intern-crossbeam-ventures-mfx.json","meta":{"generated_at":"2026-10-30T13:12:07Z","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":55,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":179794},"rest":"https://alion.io/mcp/rest/get_company?id=179794"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcrossbeam-software-engineer-intern-crossbeam-ventures-mfx"},{"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%2Fcrossbeam-software-engineer-intern-crossbeam-ventures-mfx"},{"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%2Fcrossbeam-software-engineer-intern-crossbeam-ventures-mfx"},{"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/crossbeam-software-engineer-intern-crossbeam-ventures-mfx\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcrossbeam-software-engineer-intern-crossbeam-ventures-mfx"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":467879}},{"tool":"search_jobs","arguments":{"company":"crossbeam.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":467879},"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.
