Real mission. Measured impact. Open source.
We're a small engineering-led team working on problems that matter for regulated, real-world finance on-chain — and we work in the open.
A mission that matters
Two slow-moving, existential risks — infrastructure debt and the quantum threat — converging on 20–30 year trade documents. The work has weight, and a clear reason to exist.
Measured, not promised
We ship to XDC mainnet and measure it: four clients live, a modern-geth node 3× smaller on disk and ~40× lighter on CPU, bit-exact consensus parity. Your work shows up in production numbers.
Open source by default
Our client and tooling work lives in public repositories. Read the code, see how we work, and contribute before you ever apply — github.com/XDCIndia.
Remote & async
We're remote-first and asynchronous. We optimise for deep work, clear written communication, and outcomes over hours-at-a-desk.
Hard, current problems
Path-based state, snap sync, multi-client diversity, NIST post-quantum signatures (ML-DSA / Falcon), hybrid signing. Modern protocol engineering, not maintenance of legacy forks.
Ahead of the deadline
DORA, CNSA 2.0, the EU PQC roadmap (2030) and NIST deprecation (2035) are all coming. We're building for them now — your work is early, not reactive.
Roles we're typically hiring for
These are the kinds of people we usually want to talk to. We don't run an applicant-tracking system — every application goes straight to a human.
These listings are illustrative — they describe the profiles we typically hire for, not a live, guaranteed-open requisition list. If something fits, reach out anyway; we open roles as the work demands.
Work on the XDSS-PQ standard: NIST ML-DSA (FIPS 204) and Falcon (FIPS 206), hybrid signing, and migrating XDC's quantum-exposed surface. Comfortable reading specs and turning them into code.
Maintain and extend the XDPoS engine on a modern go-ethereum base (v1.17.3) — consensus, state, sync — while preserving bit-exact parity with the canonical chain.
Contribute to XDC's client-diversity story on the Rust side (Reth-family work) — execution, sync and tooling — as part of a multi-client mainnet.
Run and measure a fleet of heterogeneous clients (go-ethereum/GP5, Erigon, Nethermind, Reth) on XDC mainnet — deployment, observability, snap sync and the measurement harness behind our published numbers.
Help developers build on XDC: documentation, examples, technical writing and community engagement around our infrastructure and post-quantum work.
