We are building the next generation of the AWS backend that produces that data: the services that assemble aeronautical navigation files and deliver them to airlines and avionics manufacturers in the formats their systems can read.\nThe hard part is volume against a deadline. The system has to produce several hundred large files inside a short window, every publication cycle, without failing. You will work on the architecture that makes that hold: how the work is distributed, what happens when something breaks mid-run, and how the whole thing scales when new product types are added.\nYou will not be building this alone. Several component teams own different parts of the pipeline, so a good share of the work is designing clean integration points and getting them to work together.\nKey responsibilities\nDesign scalable and resilient backend architecture that can support growth, high processing volumes, and new products with minimal engineering effort.\n\nApply cloud security best practices across services, infrastructure, automation, access control, and deployment processes.\n\nIdentify and mitigate risks, issues, and technical debt in backend services and cloud infrastructure.\n\nCollaborate with other component teams for integration activities.\n\nDocument technical decisions, risks, and operational procedures so other teams can act on them.\n\nRequired qualifications\nProduction experience developing with Python and PostgreSQL.\n\nExperience developing and operating in AWS environments, including cloud-native architecture patterns and common cloud operational practices.\n\nFamiliarity with cloud security best practices, including access control, patch management, secrets handling, and secure service configuration.\n\nExperience with static analysis and code scanning tools such as SonarQube, and with keeping code quality gates in place as a system grows.\n\nAbility to diagnose and resolve issues across application code, infrastructure, containers, databases, and cloud services.\n\nExperience using AI-augmented development tools such as Claude, Codex, or similar coding assistants in real production work, with your own approach to reviewing and verifying what they produce. You stay accountable for the quality, security, and maintainability of the result.\n\nAbility to work independently on moderately complex technical problems while collaborating with senior engineers and cross-functional teams in a global environment, with the communication skills that requires.\n\nPreferred qualifications\nExperience with JavaScript and a modern frontend framework such as React or Angular.\n\nExperience with the Java language.\n\nExperience developing software within a regulated environment such as aerospace, financial, or medical domains.\n\nHands-on experience with Linux and Docker.\n\nExperience with database performance troubleshooting, schema changes, or data migration.\n\nExperience improving CI/CD, HA/DR, monitoring, alerting, and incident response practices.\n\nExperience building agentic engineering workflows for complex codebases, including repository instructions, automated verification, or developer tooling.\n\nAbout Jeppesen ForeFlight\nJeppesen ForeFlight makes the flight planning, navigation and charting software that pilots use in the cockpit. Airlines, business aviation operators and avionics manufacturers rely on our aeronautical data, and that data has to be correct every time it is published.\nOur Gdansk office is one of the company’s engineering sites in Europe. You would join the Data Delivery and Enablement organisation, working on the systems that assemble and deliver navigation data products to customers on a fixed publication cycle.\nTech stack\nPython\nPostgreSQL\nAWS\nfastapi\nDistributed systems\nDocker\nCI/CD\nAI-Agmented Tools\nLinux\nSonarQube","description_format":"text","description_chars":3861,"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":[],"hiring_locations":[{"name":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Commercial Aviation"],"lifecycle":[{"event":"open","at":"2026-10-15T14:25:00Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":29,"reasons":["seen:0","win:early"],"computed_at":"2026-10-15T20:13:57Z"},"pay":{"stated_usd_annual":77532,"is_top_pay":false},"html_url":"https://alion.io/job/jeppesen-foreflight-senior-backend-developer-python","json_url":"https://alion.io/job/jeppesen-foreflight-senior-backend-developer-python.json","meta":{"generated_at":"2026-10-15T20:13:57Z","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":30717,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":2190871},"rest":"https://alion.io/mcp/rest/get_company?id=2190871"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fjeppesen-foreflight-senior-backend-developer-python"},{"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%2Fjeppesen-foreflight-senior-backend-developer-python"},{"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%2Fjeppesen-foreflight-senior-backend-developer-python"},{"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/jeppesen-foreflight-senior-backend-developer-python\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fjeppesen-foreflight-senior-backend-developer-python"}]}
