Yet knowledge gets stuck in tools and SharePoint folders - or disappears when experts leave. While IT is still planning, employees are already using ChatGPT and the like - without governance, and sensitive data is leaking out.\nWith the Knowledge Bots platform, Blockbrain creates what companies truly need: AI-powered knowledge management that is quick to implement, flexibly scales, and operates in a compliant manner. Teams use our GenAI building blocks to build tailored AI assistants, agents, and workflows in minutes - just like Lego.\nSeries A funded with strong growth momentum (10x product usage & 5x revenue in 2025)\n\nEnterprise clients such as Roland Berger, Bosch, IONOS, and Harting from industries including manufacturing, finance, and legal - sectors with the highest security requirements\n\nISO 27001 certified, EU AI Act ready. Made in Germany.\n\n Role & Impact\nYou’ll work across our engineering organization. In areas like Agents, Knowledge, Enterprise, or Mobile - taking meaningful, sometimes ambiguously defined problems from understanding through implementation to production monitoring. You’ll own problems end-to-end, make technical decisions within your scope, and use coding agents as a core part of how you build. Not as a novelty, but as a multiplier for speed, quality, and technical depth.\nResponsibilities\nOwn problems end-to-end: Understand the why before touching the code, ship robust solutions with tests and observability, and follow through in production.\n\nMake sound technical decisions: Choose the right approach within your scope and stand behind it.\n\nWrite strong code reviews: Catch real issues such as logic errors, missing edge cases, weak abstractions, and technical debt early.\n\nSurface risk proactively: Identify technical risks before they turn into incidents or product issues.\n\nCollaborate cross-functionally: Work closely with Product, Design, and other Engineering teams to turn ambiguous requirements into clear solutions.\n\nMentor other engineers: Support Junior and Mid-Level Engineers with concrete, actionable feedback on real work.\n\nContribute to operational excellence: Participate in incident reviews and help turn learnings into lasting improvements.\n\nUse AI as part of the workflow: Leverage AI tools and coding agents to structure work, accelerate implementation, and improve documentation and code quality.\n\n Profile\nSeveral years of experience in product-focused software engineering, ideally in complex, distributed, or fast-moving environments.\n\nStrong TypeScript experience: You feel at home in TypeScript monorepos and build maintainable, production-ready software.\n\nPragmatic Python knowledge: You use Python where it adds value.\n\nSolid infrastructure mindset: You are comfortable with Kubernetes, containerized environments, and Infrastructure as Code.\n\nDistributed systems thinking: You understand event-driven architectures, scalable services, and cloud-native patterns.\n\nProduction-minded: “Merged” does not mean “done” - you care about observability, reliability, and long-term maintainability.\n\nTechnically decisive and honest about complexity: You clarify unclear requirements early and communicate trade-offs clearly.\n\nGenuinely curious about AI systems: You’re interested in agent runtimes, workflow orchestration, retrieval pipelines, and tool use - and you’re open to using AI daily as a co-pilot.\n\nWhat Blockbrain Offers\nFlexible Work Models: Full-time position on-site in Stuttgart (3 days per week) with flexible working hours.\n\nBenefits: Deutschland-Ticket, Wellpass fitness membership, access to the latest AI tools, and regular company and team off-sites.\n\nTop Team: International team with exceptional talents.\n\nHigh Growth Potential: Steep learning curve in a fast-growing AI startup. A high level of personal responsibility and the freedom to actively shape processes.\n\nTop Equipment: MacBook, iPhone, headset, and all the tools you need to perform at your best.\n\nBlockbrain is an equal opportunity employer. We celebrate diversity and are committed to an inclusive work environment.\nCompensation\n€75.000—€85.000 EUR","description_format":"text","description_chars":4190,"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":["Apple Macbook","Flexible schedule"],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Cybersecurity","Information Security","Security Compliance"],"lifecycle":[{"event":"open","at":"2026-09-26T03:27:13Z"}],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.347,"p_room":0.28,"age_days":101,"expected_fill_days":24,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-09-26T05:45:00Z"},"pay":{"stated_usd_annual":97576,"is_top_pay":false},"html_url":"https://alion.io/job/blockbrain-senior-fullstack-software-engineer-mfd","json_url":"https://alion.io/job/blockbrain-senior-fullstack-software-engineer-mfd.json","meta":{"generated_at":"2026-09-27T03:05:10Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2818,"day_limit":5000,"remaining_today":2182,"minute_limit":60,"resets_at":"2026-09-28T00:00:00Z"}}}
