Immediate Joiner

Company Description

TopGrep Tech, an ISO 27001:2022 and DPIIT-certified IT pure tech product & services company. We work with global enterprises & startups, covering SaaS, MVPs, AI, RAG, MCP, reliability engineering, DevOps, and cloud innovation.

Role Description

This is a full-time on-site role located in the Greater Bengaluru Area for a Full Stack Engineer. The Full Stack Engineer will design, build, and maintain both front-end and back-end components of web applications. Candidates must demonstrate independent coding ability. Generative AI tools, AI coding assistants, and vibe-coding tools are not permitted during coding interview rounds. They will collaborate with cross-functional teams to deliver high-quality software solutions, ensure efficient system performance, and troubleshoot and resolve bugs and technical issues. This role also involves optimizing applications for maximum speed and scalability while following best practices and coding standards.

Qualifications

• Experience with Back-End Web Development, including server-side programming, APIs and database management
• Proficiency in Front-End Development, including JavaScript & Reactjs frameworks
• Strong foundation in Software Development and Full-Stack Development
• Ability to write, optimize, and debug code
• Excellent problem-solving and communication skills
• Familiarity with version control systems such as Git
• Experience with cloud platforms
• Bachelor's Engineering or Masters degree in Computer Science with equivalent practical experience

Requirements added by the job poster

• Bachelor's Degree

• Commute to this job’s location

• 1+ years of work experience with JavaScript Frameworks

• Working in an onsite setting

• 1+ years of Software Development experience

Job Responsibilities:

• Design an API, not only implement one.
• Reason about indexes, query plans, transactions, migrations on live tables.
• Handle vendor and third-party integrations, done well: authentication, retries, idempotency, webhooks, rate limits, sandbox-to-production rollout, and reconciliation when the other side fails mid-flow.
• Work directly with a vendor's technical team to get an integration over the line.
• Manage Queues, background jobs and scheduled work, including what happens when a job runs twice.
• Perform React with TypeScript.
• Execute Component design, state management, forms that hold up under real user behaviour.
• Build a clean screen without a pixel-perfect design handed to you using enough CSS and layout sense.
• Ensure Performance and correctness on the browser side: loading states, error states, the ugly edge cases.
• Write Tests you actually write.
• Maintain Git discipline, CI/CD, and enough DevOps grounding to be self-sufficient: containers, environment configuration, pipelines, deployments and rollbacks.
• Understand AWS fundamentals: how your service runs, scales and fails.
• Instrument what you build logs, metrics, alerts so problems surface on a dashboard rather than in a customer complaint.
• Read monitoring output and act on it: triaging an alert, finding the root cause, and closing the loop with a fix or a tuned threshold rather than muting it.
• Keep an eye on infrastructure cost.
• Know roughly what your service costs to run, spotting the query, log stream or API call pattern that is quietly expensive, and factoring that into design decisions.
• Understand the problem first-hand.
• Spend time with the product owner or the ops team that has the problem, and see how the work happens today rather than working from a requirements document alone.
• Design, build and ship end to end.
• Take it to production and keep it healthy.
• Deploy it, monitor it, and act on what the monitoring tells you.
• Watch for Errors, latency, failed jobs and data quality and ideally spot the issue before someone reports it.
• Be mindful of what it costs to run.
• Think about instance sizing, storage, query patterns, log volume and the cost of third-party API calls before you ship, and raise it early when something is likely to get expensive.
• Integrate cleanly with vendors and partners.
• Work well with vendor teams, reading their documentation carefully and handling their failure modes gracefully.
• Be accountable for what you commit to.
• Give estimates you believe in, flag slippage early, and keep the status visible.
• Leave it documented.
• Build securely by default.
