It's a distinction! It means you have built successful products in the past, faced mysterious production errors and came out on top of them, know how to get stuff done right, not just fast, and you are not afraid of working on hard problems that haven't been solved before.\nBeing a Senior Backend Engineer means you can see a feature's implications for the database, API and related services - even for complex topics like scheduling and other NP-hard problems. You'll be working in our AI & Optimization Team with teammates who \"know their stuff\" - colleagues who are there when you need them and who will rely on you and your engineering expertise. The automation framework and simulation engine at the core of our product will be your home turf: you'll design, build and evolve them together with the team - from the algorithms inside to the APIs they expose. We don't have dedicated architects or tech leads because frankly - if you're a true senior - you should be capable of creating a great first draft yourself.\nAdditionally you will have Full Stack colleagues doing the heavy lifting to incorporate the systems you build into our application.\nYou will be working at the heart of our planning and scheduling engine. We are rapidly changing and evolving our core logics and algorithms to achieve a lasting positive impact on the performance of our customers' supply chains. The backend is a hybrid combination of automation, simulation, and optimization components. You will be working on extending our core engine, improving performance, modeling new constraints, and more.\nYou will be facing complex requirements in a complex domain - which is inherently not mathematically end-to-end solvable. So if you are keen to work on scalable, generic solutions for complex mathematical problems - you have found your match!\nWhat you will be doing\nExtend our simulation and automation engine (mainly constraint propagation & complex state searches) in Python\nDesign and implement algorithms for scheduling and planning problems together with the team\nInterface design and evaluation of simulation and optimization components for web services & APIs\nBenchmark and improve performance of critical backend services\nSet up APIs and services to integrate our automation backend with the rest of the application\nDevelopment of a DSL-like automation engine using different technologies (mostly hybrid systems between Python and Rust)\nPorting performance critical code from Python to Rust (with Python bindings)\nTest suite maintenance and extension for simulation and optimization components\nRequirements\nExtensive knowledge and expertise in coding in Python (staff level knowledge)\nExtensive knowledge and expertise in coding in Rust (3 years or more experience)\nExperience in building performance critical backend services\nExperience building long-term sustainable software end-to-end\nCapability to work independently on complex subtopics\nCapability to work in large and complex codebases\nNice to have\nExperience in designing and developing DSLs\nExperience in classical mathematical optimization\nExperience in heuristic search algorithms\nExperience with meta-heuristic optimizations\nTech-Stack\nRuff\nuv and ty\nFastAPI\nPydantic/Pydantic AI\nHypothesis\nPyArrow\nNumba\nBenefits\nAt our company, we believe people do their best work when they feel supported, connected, and empowered. Here's what you can look forward to:\nAnnual compensation plus significant stock options\nRelocation Package - We provide full support to help you settle in smoothly, including relocation assistance and accommodation guidance\nWellpass Gym Membership - Access to hundreds of fitness and wellness options for just €10/month\nJob Ticket - Subsidized public transport to keep your commute affordable and stress-free\nGerman Language Courses - Learn or improve your German with our supported language program\nSnacks, Drinks & Great Coffee - Always available to keep you fuelled and focused\nModern Office with a View - Work from our beautiful Hamburg office with panoramic city views\nSupportive & International Team - Join a warm, open-minded group of colleagues from around the world\nReal Ownership - You'll have space to take initiative and make a tangible impact\nFlexible Working Hours - Because we understand that life and studies don’t always fit a 9-5\n Regular Team Events - From lunches to offsites-we celebrate the wins (big and small) together","description_format":"text","description_chars":4521,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"German","level":"All levels","optional":true}]},"benefits":["Flexible schedule","Gym membership","Relocation assistance","Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Supply Chain & Logistics Software","Manufacturing & Industrial Software"],"lifecycle":[{"event":"open","at":"2026-09-12T17:21:40Z"}],"visa":[],"liveness":{"score":16,"band":"cold","label":"Long shot","p_open":1,"p_active":0.565,"p_room":0.28,"age_days":85,"expected_fill_days":32,"reasons":["conf:5","win:tail","crowd:"],"computed_at":"2026-11-06T05:58:05Z"},"pay":null,"html_url":"https://alion.io/job/akeno-seniorstaff-backend-engineer-rustpython","json_url":"https://alion.io/job/akeno-seniorstaff-backend-engineer-rustpython.json","meta":{"generated_at":"2026-11-07T00:38:07Z","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":1566,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":670057},"rest":"https://alion.io/mcp/rest/get_company?id=670057"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fakeno-seniorstaff-backend-engineer-rustpython"},{"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%2Fakeno-seniorstaff-backend-engineer-rustpython"},{"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%2Fakeno-seniorstaff-backend-engineer-rustpython"},{"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/akeno-seniorstaff-backend-engineer-rustpython\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fakeno-seniorstaff-backend-engineer-rustpython"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":832769}},{"tool":"search_jobs","arguments":{"company":"akeno.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":832769},"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.
