This role is for one of the Weekday's clientsMin Experience: 2 yearsLocation: Bengaluru, Pune, Hyderabad, ChennaiJobType: full-timeWe are looking to hire fullstack engineers (from SDE-2 to Staff) to take full ownership of this platform, managing everything from dynamic, responsive frontends to the backend services and workflows that support them.The differences between levels lie in scope, ambiguity, and impact — yet at every level, you will write code, deliver products, and work seamlessly across the frontend-backend interface.RequirementsKey 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 frontends
Design and implement APIs
Ensure seamless integration between UI and backend systems

SDE-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 workflows
State management and persistence
Error handling and fallback strategies
Scalable API design

Real-Time & Event-Driven SystemsImplement real-time patterns using WebSockets, SSE, or async workflows:

Live updates
Progress tracking
Partial results and responsiveness

Make tradeoffs around latency, consistency, and user experience.User Control & Workflow DesignBuild systems that allow users to:

Review and approve actions
Override system decisions
Intervene in workflows when needed

Senior+ engineers help define how control, automation, and usability are balanced.Performance & ReliabilityOptimize across the stack:

UI performance and rendering
Backend query efficiency
Caching and throughput
System reliability and observability

Senior and Staff engineers define SLOs and performance standards.Code Quality & Mentorship

Write clean, testable, maintainable code
Participate in code reviews
Mentor 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 abstractions
Resolve architectural ambiguity
Align engineering decisions with product goals

Staff engineers drive org-wide technical direction.QualificationsThe engineering progression from SDE-2 to Staff Engineer reflects a clear increase in technical depth, ownership, and strategic influence. An SDE-2 typically brings 3–5 years of full-stack experience, with strong proficiency in React and TypeScript on the frontend and a solid grasp of API design and database fundamentals on the backend. At this stage, engineers are exposed to moderately complex workflows, are familiar with asynchronous patterns, and can execute well-defined tasks independently while understanding user flows and product basics. Their communication is clear and structured, enabling effective collaboration within teams.A Senior Engineer, usually with 5–8 years of experience, demonstrates deeper expertise across both frontend and backend systems. They possess strong React knowledge, along with hands-on experience in building robust backend systems involving queues, caching, and authentication. Senior engineers have built production-grade systems, exercise strong architectural judgment—especially in real-time scenarios—and are capable of designing for edge cases, scalability, and trade-offs. They operate with a high degree of independence, make key technical decisions, and effectively communicate complex trade-offs across cross-functional teams.At the Staff Engineer level, with 9+ years of experience, the role evolves into one of technical leadership and system-wide impact. These engineers are experts in frontend architecture and distributed systems, capable of designing and scaling large, complex infrastructures. They define real-time system patterns, influence long-term technical direction, and shape both product and engineering strategy. Their impact extends beyond individual contributions to organization-level leadership, guiding teams and aligning business, product, and technology goals. Communication at this level involves bridging strategic priorities across stakeholders while driving clarity and execution at scale.Nice to Have
