Who We Are ParamAIQ is an applied-AI company building NyaayOS, the reasoning layer for Indian law. We turn the primary sources of Indian law, from the BNS, BNSS and BSA to decades of Supreme Court and High Court precedent, into something any advocate can stand on. Work that took days takes minutes. India has more than 55 million pending cases, and the outcome for a litigant can turn on who they can afford. We're building the foundation that gives an independent lawyer the same analytical leverage as a partner at a leading firm, and we build it with practising lawyers, not just for them. Why This Role Matters A lawyer won't file anything on the strength of an answer they can't check. In ParamAIQ, the interface is where trust is won or lost. Every answer has to show where it came from, how sure we are, and whether the law it cites is still good, and the lawyer has to be able to verify it in one click. You'll build that. This is a senior, hands-on role: you make the frontend architecture calls, and you write the code that matters most. What You'll Own
• The product: The architecture and the code of the app lawyers and firms log into.
• Search: Millions of judgments, orders, and statutes, with filters by court, judge, section, and date, and results a lawyer can scan in seconds.
• The research assistant: Answers that stream in, live progress while it searches and reads, and a citation on each claim that opens the source at the right paragraph.
• Evidence on every answer: Sources, confidence, and whether a cited judgment has since been overruled.
• The drafting editor: Citations and defined terms as live objects, formatting that follows each court's rules, and PDF and Word export that's ready to file.




• The document viewer: Long judgments in PDF or text, with the cited passage highlighted.
• Matter workspaces: Where a firm keeps its research and drafts, visible only to the people who should see them.
• Speed in real

conditions:
Long documents, streamed answers, mid-range laptops, and office connections that drop.
• The design system: Built with our designer, so the product looks and behaves as one thing.
• Internal tools: The software our legal, research, and operations teams run on, with the same care as the product. The Hard Problems You'll Take On
• Showing uncertainty without hiding the answer: Making it visible, claim by claim, when an answer is part grounded, part inferred, or leans on an overruled judgment, without burying the lawyer in warnings.
• Making slow, fallible AI feel dependable: Show progress honestly, handle partial and failed results gracefully, and never present a half-finished answer as a finished one.
• An editor that knows what it contains: Clauses, citations, and defined terms as structured objects that can be checked and flagged when the law changes, while the lawyer still types as freely as in Word. What You Bring
• You've shipped a complex web app that people use for real work, in TypeScript and React or a similar framework,



and can talk through a hard architecture call you made in it
• Deep browser knowledge: you can profile a slow page, find what's blocking it, and keep a large interactive screen quick against Core Web Vitals
• Streaming and async UI: server-sent events or WebSockets, cancellation, and the error and partial states most apps skip
• Accessibility and tests are part of done for you, not a later ticket
• Comfort working with backend and research to decide what an answer must carry, so the screen can show it honestly
• Happy to be in the code, down to the empty states Bonus Points
• A rich-text editor built on ProseMirror, Lexical, or similar, taken well past the default setup
• AI products: streamed model output, citations, confidence, or human-review interfaces
• Document-heavy interfaces: PDF rendering, virtualised long documents, highlights and annotations
• A design system built from zero This Isn't the Role If
• You think a spinner is a finished design for a ten second wait. Most of the hard work is in the states between "loading" and "done."
• You want a mature design system to work inside. We're building it.
• You want the backend to hand you finished data.
• You want to architect and hand off. What You Get
• Real ownership of frontend architecture and the code that matters most, from day one
• The chance to build a design system from zero, alongside our designer
• Work shoulder to shoulder with practising lawyers on a product built for real legal work
• A hand in making justice more accessible in one of the largest judicial systems on earth
