We process millions of interactions across WhatsApp, Facebook, and Instagram, leveraging cutting-edge AI, NLP, and Automation to create seamless experiences.\nFounded in 2017, we've built a robust, high-growth product that powers hundreds of businesses. At Glassix, we value autonomy, curiosity, and high-impact initiative. If you're a builder who wants to see your code affect millions of users in real-time, you belong with us.\nThe Role\nEvery conversation on Glassix eventually becomes a line on an invoice. We're looking for a Junior Fullstack Developer to join the team that owns our billing platform: the system that meters usage across millions of messages and turns it into plans, invoices, and payments.\nBilling is one of the best places to learn how a SaaS company really works. You'll see how product decisions become pricing, how pricing becomes code, and how code becomes revenue. You'll work with experienced engineers who will help you grow, and you'll ship real features that customers rely on every month.\nWhat You'll Do\nBuild and ship billing features end to end, from database to React UI\n\nWork on usage metering, subscription plans, and pricing logic as new products and channels launch\n\nHelp maintain our integrations with payment providers and invoicing flows\n\nLearn to design reliable, well-tested processes for tricky cases like upgrades, downgrades, proration, retries, and refunds\n\nBuild the customer-facing billing experience: plan management, usage dashboards, and invoice history\n\nCollaborate with Finance, Product, and Customer Success to turn business rules into working software\n\nTake part in the full development cycle: design, development, code review, deployment, and monitoring\n\nOur Tech Stack\nReact\n\n.NET Core\n\nMS SQL, Redis, MongoDB, and Elasticsearch\n\nCloud: AWS, Azure, GCP\n\nWho You Are\nWe're looking for someone who:\nHas some hands-on experience with web development (React, .NET, or similar), whether from work, studies, or personal projects Is comfortable with SQL and understands the basics of working with relational data Pays attention to detail and cares about getting things right, not just getting them done Enjoys solving complex problems and thrives in a fast-paced startup environment Takes ownership, has a proactive mindset, and isn't afraid to ask questions or challenge the status quo Is eager to learn, adapt, and contribute to a growing team\nWhy Join Us?\nMake an impact: Billing is how the company gets paid. Your work will be directly tied to revenue and customer trust from day one. Collaborate & grow: Work alongside experienced engineers who value mentoring and knowledge-sharing. Exciting challenges: We're scaling fast, and monetization is evolving with us. There's no shortage of interesting problems.\nWhat to Expect\nThings move fast here-priorities can shift as we learn and grow. We love fresh ideas! If something in our pricing or billing flow doesn't seem right, we want you to speak up. There's some legacy code, but nothing scary-we're constantly improving and refactoring. Precision matters in this domain. We test carefully, review thoroughly, and we'll teach you how we do it.\nRequirements\nA degree in Computer Science or a related field is required.\n\n5 Matriculation units in Math/Physics\n\nWe are looking for someone who can start immediately.\n\nIf this sounds like the kind of place where you’d thrive, let’s talk!","description_format":"text","description_chars":3505,"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":["Artificial Intelligence","AI Agents","Call Center Services"],"lifecycle":[{"event":"open","at":"2026-09-15T19:23:44Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":1,"p_active":0.453,"p_room":0.28,"age_days":51,"expected_fill_days":21,"reasons":["conf:2","win:tail","crowd:junior"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/ai-junior-fullstack-developer-billing-monetization","json_url":"https://alion.io/job/ai-junior-fullstack-developer-billing-monetization.json","meta":{"generated_at":"2026-10-30T20:35:54Z","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":10615,"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":677845},"rest":"https://alion.io/mcp/rest/get_company?id=677845"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fai-junior-fullstack-developer-billing-monetization"},{"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%2Fai-junior-fullstack-developer-billing-monetization"},{"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%2Fai-junior-fullstack-developer-billing-monetization"},{"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/ai-junior-fullstack-developer-billing-monetization\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fai-junior-fullstack-developer-billing-monetization"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":942698}},{"tool":"search_jobs","arguments":{"company":"glassix.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":942698},"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.
