Ph3Your mission /h3 pYour mission is to develop and maintain intuitive, high-performance web applications and APIs that provide seamless access to OKAPI:Orbits’ end-to-end solutions across Mission Design, Space Situational Awareness (SSA), Space Traffic Management (STM), Flight Dynamics (FD), and Space Traffic Coordination (STC), supporting the entire lifecycle of satellite operators strongwithin an initially fixed-term contract until the end of 2026, with a high likelihood of a subsequent extension of up to two additional years, and a planned start date of April 1, 2026. This position is employed through OKAPI:Orbits liitty Spanish legal entity /strong. /p pYou design and implement elegant user interfaces and robust service integrations that connect complex space-data pipelines with an accessible, reliable user experience. /p pYou work on the systems that enable satellite operators and space agencies to visualize, plan, and manage their missions efficiently in an increasingly dynamic orbital environment. /p pResearch shows that women are less likely than men to apply for a position unless they meet 100% of the listed requirements. Please know that if it’s your case — but you are passionate about space technology, building reliable software, and contributing to a more sustainable space environment — we strongly encourage you to apply. /p pOKAPI:Orbits already brings together a highly diverse team, eisen we actively continue to strengthen this diversity, as research consistently shows that heterogeneous teams achieve higher performance and drive innovation. /p h3Your tasks and responsibilities /h3 ul liDesign, develop, and maintain strongscalable web frontends using Next.js /strong and strongNode.js-based APIs /strong /li liImplement and optimize stronguser-friendly, high-performance, and secure web applications /strong for satellite operators and space agencies /li liDesign and maintain stronginterfaces between frontend, API, and microservices /strong, including authentication, authorization, and data flow management /li liCollaborate closely with strongscientists and engineers /strong to translate complex domain requirements into userорот-centric software solutions /li liTake ownership of strongfrontend architecture, performance, usability, and maintainability /strong /li liPlan and document strongimplementation steps /strong, from technical design to production deployment /li liEnsure strongcode quality /strong, automated testing, and adherence to strongsecurity and development standards /strong /li liContribute to the improvement of strongCI/CD pipelines, monitoring, and automation /strong to support reliable and continuous delivery /li liAnalyze and resolve strongcomplex issues /strong across frontend, API, and data layers with a focus on reliability and user experience /li liWork in strongsmall, interdisciplinary teams /strong, bringing your full-stack expertise into cross‑functional projects /li /ul h3Your profile /h3 pstrongMust-haves /strong /p ul liDegree in strongComputer Science /strong, strongSoftware Engineering /strong, or a related field, or formal strongIT specialist training /strong /li listrongSeveral years of hands‑on experience /strong building production‑grade applications with strongReact.js /strong, strongNode.js /strong, and strongTypeScript /strong /li liRealm understanding of strongJavaScript fundamentals /strong, asynchronous programming, and modern ECMAScript features /li liStrong strongMongoDB expertise /strong: schema design, data modeling, indexing, aggregation, and performance optimization in high‑load systems /li liExperience with strongRESTful API design /strong and integration, including authentication, authorization, and versioning /li liFamiliarity with strongGit‑based workflows /strong, pull requests, and collaborative code reviews /li liProven ability to strongdebug complex issues /strong across frontend, backend, and data layers /li liFocus on strongclean, maintainable code, testing, and long‑term software reliability /strong /li liProactive communication and strongteam‑oriented mindset /strong, comfortable working in distributed setups /li listrongGood English /strong, written and spoken /li /ul pstrongNice-to-haves /strong /p ul liExperience with strongNext.js 15+ /strong, including strongReact Server Components /strong, strongSSR /strong, or strongISR /strong for performance‑_has frontends /li liExperience with strongDocker /strong and strongKubernetes /strong for local development, deployment, and scaling of services /li liFamiliarity with strongmicroservice architectures /strong /liliExperience with strongPython /strong or strongJava /strong, particularly for backend or data‑processing pipelines /li liKnowledge of strongCI/CD tools /strong (GitLab CI) and strongfrontend testing frameworks /strong (Cypress, Vitest, Jest) /li liExperience with strongmonitoring and observability /strong (DataDog, Sentry, OpenTelemetry) /li liExposure to strong3D visualisation frameworks /strong such as strongCesiumJS /strong or WebGL libraries /li liInterest or experience in the strongspace or aerospace domain /strong /li liExperience in strongmentoring /strong or strongtechnical leadership /strong within agile teams /li /ul h3Why us? /h3 ul listrongFlat hierarchy /strong, strongsmall teams /strong, flexible hours /li liOnboarding in strongBraunschweig /strong, afterwards strongremote from Spain /strong /li liEarly ownership, stronginfluence technical direction /strong /li listrongTraining budget /strong for continuous development /li listrongGerman classes via Lingoda /strong /li liJoin strongspace events and conferences /strong, advocate for sustainable space /li /ul /p #J-18808-Ljbffr
