You'll be joining a people-focused company as a Software Engineer on Vendavo's Enterprise CPQ (eCPQ) platform - a greenfield, event-sourced, cloud-native product being built on AWS, while our established CPQ and Pricepoint products continue to serve customers in production.\nThis is a backend-focused role on a platform built around event sourcing and CQRS: aggregates, commands, events and projections, with services communicating through streamed events rather than shared databases. If you haven't worked this way before, that's fine - we care that you've built solid .NET services, that you think carefully about data and failure modes, and that you want to learn this properly. You'll have senior engineers alongside you, an explicit event model to work from, and a codebase where the patterns are already established.\nYou'll also work with AI coding agents every day. That's not a bonus here - it's how the team ships, and we expect you to be comfortable with it and critical about it.\nTHE OPPORTUNITY\nBuild and extend event-sourced .NET services on .NET 10 / ASP.NET Core, deployed to AWS EKS behind an Istio service mesh\nImplement aggregates, commands, events and read-model projections using Marten (PostgreSQL event store) and Wolverine (command handling and messaging)\nImplement vertical slices from the event model through to a working feature - backend handlers, projections, GraphQL API and the React screens that use them - with design support from senior engineers on the harder calls\nBuild GraphQL APIs with Hot Chocolate, including filtering, sorting, pagination and multi-tenant request handling\nWork with AWS Kinesis streams and Amazon MSK (Kafka) for cross-service integration, and learn to design handlers that are idempotent and safe to replay\nRead and update the team's event models (draw.io), keeping them in step with the code, and take part in the modelling sessions where new slices are shaped\nWork with the Terraform infrastructure and Helm deployments for your services, and with the Azure DevOps pipelines that build, deploy and test them - extending both under review\nUse AI coding agents as a normal part of delivery: the shared ecpq-skills plugin, per-repo CLAUDE.md/AGENTS.md conventions, and AI-assisted PR review - with your own judgement on top of the output\nContribute to the React 18 + TypeScript frontend (urql, TanStack Query, Vite) when a feature needs full-stack delivery\nWrite meaningful tests, instrument what you build, and take part in code and design reviews\nContribute to the modernization of the established CPQ and Pricepoint products, including moving business logic out of SQL Server stored procedures into maintainable .NET code\nTHE SKILL SET\nAI-assisted engineering - expected, not optional\n3+ years of backend development in modern .NET (.NET 6 or newer)Working understanding of Domain-Driven Design and CQRS, and a real appetite to go deeper into event sourcing - projections, eventual consistency, idempotent handlers. We'll teach the specifics; you bring the instinct for modelling a domain properly\n\nComfort with asynchronous and message-driven code - queues, streams, retries, and what happens when a message arrives twice or out of order\nSolid SQL and relational data modelling; PostgreSQL experience preferred\nExperience building HTTP or GraphQL APIs that someone else consumes, and care about how they behave under error\nDocker and working familiarity with Kubernetes - enough to read a Helm chart, find your pod and read its logs\nExposure to a major cloud, ideally AWS (IAM, S3, EKS, Secrets Manager)\nCI/CD pipelines - Azure DevOps preferred - and Git-based workflows with PR review and required checks\nTesting you'd defend: xUnit, integration tests against real dependencies, and a view on what's worth mocking\nRegular hands-on use of an AI coding agent (Claude Code, GitHub Copilot, Cursor or equivalent) on real code, not demos\nAbility to break a ticket into steps an agent can execute, then review the output critically - spotting invented APIs, quiet behaviour changes and missing edge cases\nWillingness to keep agent context files (CLAUDE.md, AGENTS.md or equivalent) current, and to use the team's shared skills rather than working around them\nFull ownership of anything you merge, regardless of who or what wrote the first draft\nTHE BENEFITS\nWorking within a team of friendly, skilled people where help is always within reach\nProfessional growth and development opportunities\nUse of modern tools and access to experts\nTeam spirit in the workplace, and fun team activities\nOpportunities to learn a new field and get a deep understanding of enterprise tech\nFlexible working hours without micromanagement\nPersonal freedom and focus on individual responsibility\nCompany-sponsored events for employees, volunteer tech talks, and tournaments\nWeekly English classes, international travel opportunities\n25 days of paid vacation + 4 additional company days off to recharge your batteries (1 day each quarter) + 3 sick days + 2 days paid for charity activities\nMonthly benefits allowance, meal contributions\nMultiSport card available\nModern cozy offices in Prague, Hradec Kralove, and Ostrava, no large open-space floors or cubicles, rec room with games and books\nHigh-end laptop (Windows or Mac) and smartphone (Samsung S or iPhone), including personal use\nOption to use discounted unlimited mobile plan for family members","description_format":"text","description_chars":5475,"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":["Flexible schedule"],"hiring_locations":[{"name":"Czech Republic","iso":"CZ","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Sales Enablement","B2B Commerce","Retail & Pricing Analytics"],"lifecycle":[{"event":"open","at":"2026-10-09T21:32:31Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":3,"expected_fill_days":32,"reasons":["conf:2","win:early"],"computed_at":"2026-10-13T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/vendavo-software-engineer-backend-focus-net-cpq","json_url":"https://alion.io/job/vendavo-software-engineer-backend-focus-net-cpq.json","meta":{"generated_at":"2026-10-13T14:17:38Z","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":21978,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":7648},"rest":"https://alion.io/mcp/rest/get_company?id=7648"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvendavo-software-engineer-backend-focus-net-cpq"},{"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%2Fvendavo-software-engineer-backend-focus-net-cpq"},{"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%2Fvendavo-software-engineer-backend-focus-net-cpq"},{"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/vendavo-software-engineer-backend-focus-net-cpq\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvendavo-software-engineer-backend-focus-net-cpq"}]}
