We specialize in delivering innovative AI and technology solutions that transform how organizations operate and compete.\nOur approach combines strategic advisory services with custom development, enabling businesses to harness the power of AI and advanced technologies. We work closely with each client to design intelligent, streamlined solutions that address their specific challenges and align with their strategic objectives.\nAt Leyton CognitX , we believe that technology is more than just tools; it's a catalyst for meaningful organizational and technological transformation. Our mission is to empower companies to leverage AI and cutting-edge tech, turning complex challenges into opportunities for growth, efficiency, and innovation.\nFirst and foremost a seasoned Software Engineer, you master the design and development of robust production-grade applications. You integrate AI capabilities - LLMs, agents, RAG - into the systems you build, without being a data scientist. You may work on two types of contexts: internal Leyton CognitX projects (Java/Spring Boot), or assignments for large enterprise clients in varied stacks (Python, Node.js/TypeScript or other). The allocation is determined based on business needs and activity.\nKey Responsibilities\nSoftware Engineering - Core of the Role\nDesign and develop complete end-to-end features: APIs, business logic, unit and integration tests, deployment.\nEnsure code quality: SOLID principles, design patterns, clean architecture, code reviews, SonarQube.\nBuild and maintain robust REST APIs - versioning, security, error handling, performance.\nWork in CI/CD environments: Git flow, PR reviews, automated pipelines, regression testing.\nEnsure scalability and security of production systems.\nAI Integration - Expected Capability\nIntegrate LLMs into business applications: OpenAI, Anthropic, Mistral - via API, with token, cost, and latency management.\nBuild RAG pipelines: chunking, embedding, vector stores, retrieval - as a component of a larger application.\nImplement LLM agents with LangChain / LangGraph for automated workflows.\nMeasure and evaluate the quality of AI outputs integrated into the product (RAGAS, custom metrics, monitoring).\nLeadership & Collaboration\nMentor junior and mid-level engineers - code reviews, technical mentoring, sharing best practices.\nWork directly with clients / product owners: gather requirements, present technical solutions, adapt communication style.\nParticipate in architecture decisions and define the team's technical standards.\nProject Planning & Delivery\nTranslate business needs into robust and well-architected technical solutions.\nBreak down strategic objectives into manageable tasks, estimate workloads, and define clear delivery roadmaps.\nDrive feature delivery on time, aligned with product and business objectives.\nTrack and help resolve technical blockers to maintain team efficiency.\nPrepare and validate deliverables, ensuring smooth delivery aligned with business goals.\nIdeal Candidate Profile\n3 to 5 years of experience in software development - you are above all a solid Software Engineer.\nProficiency in Java/Spring Boot for internal projects, and ability to switch to Python or Node.js/TypeScript for client assignments.\nProven hands-on experience integrating LLMs into applications (production systems, not just notebooks).\nAbility to manage multiple projects simultaneously and prioritize effectively.\nProblem-solving mindset: brute force → optimization → edge cases - able to think out loud.\nCuriosity for applied AI, practical sense: you assess what does or does not warrant using AI in a system.\nStrong client communication skills and ability to mentor junior profiles.\nWhat We Offer\nOpportunities for professional development and advancement within a growing organization.\n\nInvolvement in large-scale worldwide projects spanning over 18 countries, providing exposure to diverse cultures and environments.\n\nCollaborative and challenging work environment, surrounded by brilliant collaborators who inspire continuous improvement and innovation.\n\nTechlabWay career growth path, offering opportunities for career advancement and skill development.\n\nModern and stylish office environment equipped with cutting-edge technologies.\n\nAccess to the latest technologies and tools, working on the forefront of innovation in the industry.","description_format":"text","description_chars":4484,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Professional development"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Management Consulting","Tax Advisory & Preparation"],"lifecycle":[{"event":"open","at":"2026-10-30T12:49:30Z"}],"visa":[],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.213,"p_room":0.28,"age_days":127,"expected_fill_days":28,"reasons":["conf:0","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/leyton-senior-java-software-engineer-ai-integration","json_url":"https://alion.io/job/leyton-senior-java-software-engineer-ai-integration.json","meta":{"generated_at":"2026-11-01T07:41:38Z","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":11808,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":1856538},"rest":"https://alion.io/mcp/rest/get_company?id=1856538"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fleyton-senior-java-software-engineer-ai-integration"},{"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%2Fleyton-senior-java-software-engineer-ai-integration"},{"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%2Fleyton-senior-java-software-engineer-ai-integration"},{"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/leyton-senior-java-software-engineer-ai-integration\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fleyton-senior-java-software-engineer-ai-integration"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3522664}},{"tool":"search_jobs","arguments":{"company":"leyton.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3522664},"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.
