Job description

# Senior Full-Stack EngineerEngineeringHybrid — Chandigarh, India5+ yearsfull timeWe are looking for a senior engineer who is comfortable owning a feature from the data model to the screen, and who has opinions about what belongs in the database versus the application.The work splits roughly between client platforms — web applications, portals and integrations for customers across the Gulf and Africa — and Enerxia, the oil and gas ERP we build and operate ourselves. Both are long-lived systems. An industrial ERP is read for ten years and written for two, and we hire for that timescale.## What you will do* Design and build features end to end: Prisma schema, domain services, API routes and the React UI on top.* Model business rules as effective-dated configuration rather than code, so a tax rate change is a configuration edit and an old document still calculates under the rule that applied on its date.* Write the tests that actually matter — permission tests and negative cases, not only the happy path.* Work directly with the people who will use the system, including non-technical finance and operations staff, and turn vague requirements into acceptance criteria.* Keep performance honest on real connections. A large share of our users are on mobile networks with variable bandwidth.* Review other people's code, and write the paragraph explaining a decision so the next person does not have to reconstruct it.## What we are looking for* Five or more years building production web applications, with real ownership of what you shipped.* Strong TypeScript, and React experience deep enough to reason about rendering and data fetching rather than copying patterns.* Solid relational database skills: schema design, indexing, transactions, and knowing why an ORM query is slow.* Experience with Next.js, or equivalent depth in another full-stack framework and the willingness to learn this one properly.* You can explain a technical trade-off in writing to somebody who is not an engineer.* Comfortable working with people in other time zones and writing decisions down rather than leaving them in a call.## Nice to have* ERP, accounting, or any domain where correctness is audited by somebody outside the company.* Multi-currency or multi-entity systems, and the arithmetic discipline they demand.* Prisma, PostgreSQL at scale, or background job and queue design.* Portuguese, French or Arabic — we publish and build in all three.* Experience in a regulated market: tax filing, e-invoicing, financial services or energy.## The honest partWhat you would actually be walking into, including the bits that are unfinished.* The stack is Next.js 15 with React 19, TypeScript throughout, Node, PostgreSQL 16 and Prisma, deployed to our own servers. No microservice sprawl.* Enerxia is real and it runs — 33 business domains, 258 data models, 167 test suites, 134 screens — but it is in pilot with two companies and thirty-six users. It is not a mature product with a large installed base, and we would rather you know that now than discover it in week two.* We have rules we do not bend: regulatory logic is dated configuration and never code, nothing transactional is deleted, every mutation is audited, and no regulatory fact gets a plausible-looking default when we do not know it. If those read as bureaucracy rather than as relief, this will be a frustrating place to work.* There is legacy in the codebase, as there is everywhere. Some of it is ours and we are not precious about it.* This is a hybrid role based in Chandigarh. It is not fully remote.## How hiring works* Send your CV and something you have built to [e-mail].* A 30-minute conversation about your experience and what you want to work on.* A technical discussion, working through a real problem from our domain. No timed algorithm puzzles.* A conversation with the people you would work with day to day, and your questions about us.* Offer. Compensation is discussed openly from the first conversation.## ApplySend your CV and something you have built — a repository, a system you shipped, a piece of writing about a technical decision you made. A short note about why this role, rather than a cover letter, is fine.Email [e-mail] is discussed openly in the first conversation. We reply to every application.
