We are looking for skilled team players who make change happen. Are you passionate about building cloud-native software and changing the way it is built with AI? Join Levi9 - a dynamic team of experts delivering cloud-native solutions for clients ranging from disruptive startups to global enterprises.\nWe're a strong community, working with modern JavaScript and TypeScript technologies and deploying on AWS, GCP, and Azure, often leveraging serverless architectures. As an Experienced Software Engineer, you will own products end to end - from architecture and design, through implementation and release, to monitoring and scaling.\nWe are looking for an experienced engineer whose core depth is backend development in TypeScript on AWS serverless, who builds software with AI agents every day, and who brings a T-shaped mindset: strong in backend, and confident owning the infrastructure (AWS CDK) and CI/CD pipelines of the services they build, without depending on DevOps for every change.\nProject, teams, requirements & duties\nWhat you will be working on?\nDesign, build, and maintain production-grade, event-driven services on AWS - Lambda, API Gateway, Step Functions, EventBridge, SQS, DynamoDB, and Aurora PostgreSQL\n\nOwn features end to end - from refinement and architecture, through implementation and testing, to release and post-release monitoring\n\nOwn the infrastructure and delivery of what you build - define it in AWS CDK (TypeScript), and build and maintain the CI/CD pipelines that test, scan, and deploy it across environments\n\nUse AI coding agents such as Claude Code every day through the full SDLC: spec, plan, build, test, and review\n\nWrite and refine specifications (PRDs, functional designs) that AI agents can build from, then review and correct the code they produce\n\nBuild and improve the team's AI setup - shared context, skills, subagents, hooks, and MCP tools - so the whole team works faster and more consistently\n\nAdd guardrails, such as tests, quality gates, and verification steps, so AI-written code is safe to ship\n\nBuild domain APIs and workflows that AI agents can use as tools, safely and under policy control\n\nWrite robust unit, integration, and end-to-end tests to ensure code quality and reliability\n\nCollaborate closely with project managers, PO, analysts, QA, and DevOps engineers to deliver reliable solutions\n\nSupport operational excellence through practices like code review and pair programming\n\nStay ahead of the curve by keeping up with AI engineering practices and integrating new tools where they add value\n\nHelp other engineers learn to use AI tools well, and mentor less experienced developers\n\nWhat do we expect from you?\n5+ years of experience in the software development life cycle, including coding standards, code reviews, source control management, building processes, testing, and operations experience\n\nStrong commercial experience building backend services in TypeScript and Node.js, running in production\n\nHands-on experience with AWS serverless services - Lambda, API Gateway, Step Functions, EventBridge, SQS/SNS, DynamoDB, or similar\n\nExperience with infrastructure as code, preferably AWS CDK in TypeScript (CloudFormation or Terraform also count)\n\nExperience building and maintaining CI/CD pipelines (GitHub Actions, Concourse, GitLab CI, Jenkins, or similar), including automated tests, security scans, and deployments across environments\n\nReal experience with AI coding tools such as Claude Code, Cursor, or GitHub Copilot, beyond autocomplete\n\nAn understanding of AI SDLC practices: context engineering, prompts and specs as code, agent workflows, and human review points\n\nA critical mindset and a healthy skepticism toward AI - you understand where it goes wrong and validate its work before it ships, keeping the quality, security, and review bar high\n\nExperience designing and consuming RESTful APIs and building event-driven architectures\n\nExperience with testing using tools like Jest, Vitest, or similar\n\nFamiliarity with both SQL and NoSQL databases (e.g. PostgreSQL, DynamoDB)\n\nExperience with logging, monitoring, and observability tools (Datadog, CloudWatch, or similar)\n\nProficiency with version control systems, especially Git\n\nSolid understanding of object-oriented programming (OOP) concepts\n\nAbility to analyze and troubleshoot technical issues across services and environments\n\nGood communication skills in English, both written and spoken\n\nNice to have:\nKnowledge of Amazon Bedrock AgentCore, or experience running AI agents in production on AWS\n\nExperience with LLM APIs, RAG, tool use, or MCP\n\nExperience with agent frameworks (Strands Agents, LangGraph, or similar), AI evaluations, and guardrails\n\nT-shaped experience beyond backend, for example: modern web frontend - React, Next.js, Python, Cloud security - IAM, KMS, secrets management (e.g. Vault)\n\nExperience with workflow orchestration and event-driven patterns, such as sagas and the transactional outbox\n\nExperience working in regulated environments, such as financial services\n\nAWS certifications (Developer, Solutions Architect, or DevOps Engineer)\n\nOur projects & stack:\nWe build cloud-native, event-driven solutions with a strong focus on AWS serverless and AI-driven development. Our stack includes: TypeScript and Node.js, AWS serverless services, PostgreSQL and DynamoDB, AWS CDK and CI/CD pipelines, AI coding agents throughout the SDLC.\nOur teams:\nDepending on the project, our teams typically include software engineers, AI engineers, QA engineers, and a delivery manager, while the Product Owner is usually on the client side.\nYour position in the organization:\nThis position will be a part of one of our departments in Belgrade, and your department Leads will be there to guide you and support your career development.","description_format":"text","description_chars":5829,"description_truncated":false,"requirements":{"experience_years_min":5,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Outsourcing & Dedicated Teams","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-11-10T20:26:12Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":1,"expected_fill_days":29,"reasons":["conf:1","win:early"],"computed_at":"2026-11-10T22:09:19Z"},"pay":null,"html_url":"https://alion.io/job/levi9-software-engineer-2","json_url":"https://alion.io/job/levi9-software-engineer-2.json","meta":{"generated_at":"2026-11-10T22:09:19Z","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":822,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-11T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":174177},"rest":"https://alion.io/mcp/rest/get_company?id=174177"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flevi9-software-engineer-2"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Flevi9-software-engineer-2"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Flevi9-software-engineer-2"},{"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/levi9-software-engineer-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flevi9-software-engineer-2"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4036369}},{"tool":"search_jobs","arguments":{"company":"levi9.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4036369},"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.
