The company’s current product is a B2B SaaS solution focused on the concept of Infrastructure as Code (IaC), enabling DevOps engineers (in both large and small organizations) to automate the management of their clouds using Terraform or OpenTofu.\nTerraform and OpenTofu themselves are used to describe cloud infrastructure configurations through code in a simple and user-friendly way. Scalr, in turn, develops a SaaS product that allows organizations to use Terraform and OpenTofu at scale.\nThe end users of the product are DevOps teams and engineers. Scalr enables centralized management and decentralized deployment of infrastructure, providing full visibility and control over what’s happening. It also offers integrations with various notification and observability solutions such as Slack, Microsoft Teams, Datadog, and others.\nAs we expand the platform, we’re seeking a Senior Backend Engineer excited to push technical boundaries and solve complex, large-scale problems.\nPosition Overview\nAs a Backend Engineer, you will play a crucial role in designing and constructing the core backend systems, which are divided into several essential aspects: a worker responsible for background tasks, a highly performant API developed using Flask based on the JSON-API specification, and an Agent that communicates with our server. The principal stack includes Python, MySQL, Go, Redis, Docker, Kubernetes, and various Python libraries for different problem domains such as cloud, networking, data, concurrency, parsers, etc. You will be an integral part of our platform, contributing significantly to ensuring its reliability, scalability, and efficiency.\nAlso at Scalr, we believe that the best software is produced when engineers take pride and ownership of the code they write, which is why engineers are expected to provide customer support. We value troubleshooting skills and customer empathy because, at the end of the day, writing good code and helping customers be successful is what lays the foundation for building great companies.\nMust-Have:\nHands-on, product-focused experience owning backend systems in production, from design through deployment and ongoing optimization (Python)\nConcurrency and parallelism (threading, multiprocessing, gevent, asyncio, etc.)\nBackend web development experience\nOOP and Design patterns\nRelational database design and query optimization\nWould Be a Plus:\nDevOps experience (Terraform, Chef, Ansible, SaltStack, etc.)\nKnowledge of Linux systems\nKnowledge of network protocols (TCP/IP stack, sockets, HTTP/HTTPS, etc.)\nExperience with Go\nExperience in full-stack web development (ReactJS)\nAs Part of Our Team, You Will Work On:\nTaking ownership of features, delivering features from idea to production\nContributing to the identification and resolution of bottlenecks and performance challenges, enhancing the overall efficiency of the system\nProviding customer support and demonstrating commitment to code quality through active participation in troubleshooting efforts\nDevelopment of remote state and operations backend for Terraform / OpenTofu\nAPI development for Infrastructure as Code platform - configuration and management of the user environment using UI/API\nIntegration with third-party services - VCS, online payments, cloud computing, etc\nImplementation of best practices for coding, testing, and deployment to uphold the quality of the codebase\nEngaging in code reviews, fostering a culture of collaboration and continuous improvement among the engineering team\nChallenges You’ll Need to Meet:\nEach task is unique and will require immersion in the subject\nStudying third-party services APIs, understanding Terraform behavior, and designing internal services\nInvolvement in extensive research and development\nModernizing legacy approaches\nScalr Offers:\nWork with an exciting engineering product in an enjoyable environment\nThe opportunity to see how your ideas and visions are realized\nAttractive compensation and benefits package\nLong-term contract and tax compensations\nFlexible schedule and possibility to work entirely remotely\nMedical insurance\n20 working days of paid vacation and 2 weeks of paid sick leaves","description_format":"text","description_chars":4346,"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":["Flexible schedule","Health insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["DevOps & Platform Engineering"],"lifecycle":[{"event":"open","at":"2026-09-11T07:12:10Z"}],"visa":[],"liveness":{"score":27,"band":"fade","label":"Fading","p_open":1,"p_active":0.597,"p_room":0.45,"age_days":59,"expected_fill_days":37,"reasons":["conf:0","win:tail"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/scalr-senior-python-developer","json_url":"https://alion.io/job/scalr-senior-python-developer.json","meta":{"generated_at":"2026-10-18T00:37:39Z","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":1072,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":694784},"rest":"https://alion.io/mcp/rest/get_company?id=694784"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fscalr-senior-python-developer"},{"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%2Fscalr-senior-python-developer"},{"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%2Fscalr-senior-python-developer"},{"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/scalr-senior-python-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fscalr-senior-python-developer"}]}
