This role is for one of our clientsIndustry: Software DevelopmentSeniority level: Mid-Senior levelExperience: 5+ yrsLocation: BengaluruJob Type: Full-timeWe may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans. If you would like more information about how your data is processed, please contact us.We’re hiring fullstack engineers (SDE-2 through Staff) to own this surface end-to-end: from rich, reactive frontends to backend services and workflows that power them.What changes across levels is scope, ambiguity, and influence — but at every level, you’ll write code, ship product, and operate across the frontend-backend boundary.Key ResponsibilitiesFrontend DevelopmentDesign and build intuitive, high-quality user interfaces that handle complex workflows — task tracking, state transitions, approvals, and user actions.Senior and Staff engineers define reusable patterns and UI primitives for teams.Fullstack Feature OwnershipOwn features across the stack:Build React frontendsDesign and implement APIsEnsure seamless integration between UI and backend systemsSDE-2s execute with guidance, Seniors own end-to-end design, Staff engineers define system-wide patterns.Backend & Service LayerBuild and evolve backend services that support:Long-running workflowsState management and persistenceError handling and fallback strategiesScalable API designReal-Time & Event-Driven SystemsImplement real-time patterns using WebSockets, SSE, or async workflows:Live updatesProgress trackingPartial results and responsivenessMake tradeoffs around latency, consistency, and user experience.User Control & Workflow DesignBuild systems that allow users to:Review and approve actionsOverride system decisionsIntervene in workflows when neededSenior+ engineers help define how control, automation, and usability are balanced.Performance & ReliabilityOptimize across the stack:UI performance and renderingBackend query efficiencyCaching and throughputSystem reliability and observabilitySenior and Staff engineers define SLOs and performance standards.Code Quality & MentorshipWrite clean, testable, maintainable codeParticipate in code reviewsMentor junior engineers (Senior+)Establish engineering standards (Staff)Cross-Team Technical Leadership (Senior & Staff)Collaborate across frontend, backend, data, and platform teams to:Define shared patterns and abstractionsResolve architectural ambiguityAlign engineering decisions with product goalsStaff engineers drive org-wide technical direction.The SDE-2 level typically requires 3–5 years of full-stack experience, with strong skills in React and TypeScript on the frontend and experience with API design and basic database concepts on the backend. Candidates should have exposure to complex workflows, be familiar with asynchronous and real-time patterns, understand user flows, and execute well-scoped work effectively. Communication should be clear and structured.The Senior level generally requires 5–8 years of full-stack experience, along with deep React expertise and strong backend systems knowledge, including queues, caching, and authentication. Candidates are expected to have built production-grade systems and demonstrate strong architectural judgment, particularly around real-time systems. They should be capable of designing for edge cases, evaluating tradeoffs, making independent technical decisions, and clearly communicating those tradeoffs across teams.The Staff level typically requires 9+ years of full-stack experience and expert-level frontend architecture skills. Candidates should have deep expertise in distributed systems and infrastructure design, with experience designing large-scale systems and defining real-time infrastructure patterns. They are expected to shape both product and technology direction, provide organization-level technical leadership, and effectively bridge business, product, and engineering teams.Nice to HaveExperience with real-time UI updates and streaming dataFamiliarity with system evaluation and testing frameworksExperience in high-stakes domains (fintech, logistics, etc.)Contributions to open-source or internal toolingExperience scaling systems from early stage to maturity (Staff)Must-have skillsReactJS, Javascript
