We started by helping companies run LLMs on their own Kubernetes clusters and now we're providing a managed variant of those same capabilities.\nOur Infrastructure today\nMulti-model inference (MiniMax, Kimi, GLM-5, Nemotron, DeepSeek) with intelligent routing, an OpenAI-compatible API and deployment ranging from our GPUs to your own VPC. The inference layer is the foundation and the API is what sits in front of it as the primary channel for broadly and reliably distributing our AI services and powers our own Kimchi harness.\nAs a Senior Software Engineer, you will have the opportunity to work on different key features of our product. All of these are high-agency roles across multiple parts of the tech stack that minimize process friction that would otherwise prevent you from shipping.\nIn every team you will own features end-to-end: design, implementation, testing, production rollout. Most projects ship in 1-4 weeks. You'll work directly with product and other engineering teams on problems that don't have textbook solutions.\nWe are currently hiring Senior Software Engineers for the following teams Agent Platform Team:\nThe Agent Platform squad builds the infrastructure that lets teams run fleets of AI agents securely, whether in the cloud or self-hosted, so work can move confidently from a developer's laptop to production environments. The platform enforces least-privilege access to resources, requires human approval before agents can touch anything critical, and logs every action agents take for full auditability. The goal is to give engineering and operations teams the confidence to scale up agent usage without sacrificing security, control, or visibility into what their agents are actually doing.\nResponsibilities:\nDesign and build distributed systems that run agent fleets at scale across cloud and self-hosted environments, with security at its core\nMake every agent action observable, auditable, and governable\nDevelop a remote-first experience of working with agents\nRequirements\nProduction experience with Go or Typescript is strongly preferred; candidates without either should demonstrate strong systems programming skills in a comparable language.\nStrong debugging, optimization, and performance-tuning skills - including query profiling, index design, and database performance tuning beyond ORM usage.\nHands-on experience with cloud platforms (AWS, GCP, or Azure) and Kubernetes is a strong plus\nObservability tooling (Prometheus, Grafana, OpenTelemetry), CI/CD and DevOps practices experience.\nStartup mindset: adaptable, proactive, and comfortable with ambiguity.\nStrong English skills, both verbal and written.\nYou've personally driven a complex project end-to-end.\n(Agent Platform) Experience in virtualization, networking, security, and Kubernetes internals is a strong plus\nWhat’s in it for you?\nCompetitive salary (€6,500 - €9,000 gross, depending on the level of experience).\nEnjoy a flexible, remote-first global environment.\nCollaborate with a global team of cloud experts and innovators, passionate about pushing the boundaries of Kubernetes technology\nEquity options.\nGet quick feedback with a fast-paced workflow. Most feature projects are completed in 1 to 4 weeks.\nSpend 10% of your work time on personal projects or self-improvement. \nLearning budget for professional and personal development - including access to international conferences and courses that elevate your skills.\nAnnual hackathon to spark new ideas and strengthen team bonds.\nTeam-building budget and company events to connect with your colleagues.\nEquipment budget to ensure you have everything you need.\nExtra days off to help maintain a healthy work-life balance.\nHiring process\nScreening call with Recruiter\nHiring Manager interview\nTechnical interview (system design)\nLive coding\nCulture Check interview with an executive\nAs part of our standard hiring process, we would like to inform you that a background check may be conducted at the final stage of recruitment through our third-party provider, Checkr.\nPlease note that Cast AI does not provide any form of visa sponsorship/work permit.","description_format":"text","description_chars":4168,"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":"All levels","optional":false}]},"benefits":["Company events","Equity"],"hiring_locations":[{"name":"Bulgaria","iso":"BG","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Virtualization & Containers","Cloud Cost & Multi-Cloud Management"],"lifecycle":[{"event":"open","at":"2026-10-02T22:24:20Z"}],"visa":[],"liveness":{"score":78,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.868,"p_room":0.9,"age_days":17,"expected_fill_days":49,"reasons":["conf:2","velocity","win:mid"],"computed_at":"2026-10-20T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/cast-ai-senior-software-engineer-kimchi-agent-platform-team","json_url":"https://alion.io/job/cast-ai-senior-software-engineer-kimchi-agent-platform-team.json","meta":{"generated_at":"2026-10-20T06:05:41Z","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":6595,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"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":54},"rest":"https://alion.io/mcp/rest/get_company?id=54"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcast-ai-senior-software-engineer-kimchi-agent-platform-team"},{"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%2Fcast-ai-senior-software-engineer-kimchi-agent-platform-team"},{"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%2Fcast-ai-senior-software-engineer-kimchi-agent-platform-team"},{"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/cast-ai-senior-software-engineer-kimchi-agent-platform-team\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcast-ai-senior-software-engineer-kimchi-agent-platform-team"}]}
