Job Description

Hiring: Senior Web3 Engineer (EVM Perps)


We’re building Matrix DEX


What you’ll build (first 6–8 weeks):

  • Next.js/React (TypeScript) trading app:

    markets list, trade ticket (long/short, leverage, TP/SL), positions/PnL, order history, funding display.

  • GMX v2 integration (Arbitrum)

    : ExchangeRouter writes, Reader/DataStore reads, Subsquid history, REST market data.

  • Gains/dydx Network integration

    : trading calls + event/indexing for stocks & indices.

  • Fee plumbing

    : UI fee receiver & referrals routed to Gnosis Safe; daily fee dashboard.
  • GeoIP gate + legal pages (front-end only, contracts permissionless).
  • Stateless indexer services: funding, OI, liq levels, oracle heartbeat; metrics to Grafana/Prometheus with Slack/Telegram alerts.


Must-have skills

  • T

    ypeScript, Next.js/React, Zustand/Redux, React Query.

  • EVM tooling

    : wagmi/viem, Ethers basics, event decoding, calldata building.

  • DeFi/perps experience with GMX v

    2 (ideally GMX v2 or similar): opening/closing perps, TP/SL orders, funding/PnL math.

  • Subgraphs/GraphQL (Subsquid/The Graph)

    and REST/WS market data ingestion.

  • Security + ops mindset:

    multisig flows (Gnosis Safe), RPC failover, observability.


Nice-to-have:

  • Gains Network (gTrade) integrator experience.
  • Exposure to Hyperliquid APIs (EIP-712 signing), dYdX/Injective/Drift ecosystems.
  • Node.js micro-services, PostgreSQL, Redis; AWS/GCP; Grafana/Prometheus.
  • Chainlink/oracle sanity checks; runbooks for market pauses/oracle issues.


Day-1 environment:

  • Next.js + TS + wagmi/viem
  • Arbitrum RPC (dual vendor), GMX REST endpoints + Subsquid, contract ABIs (ExchangeRouter/Reader/DataStore/ReferralStorage/EventEmitter)
  • Gnosis Safe for fee routing; Slack/Telegram for alerts


Success looks like:

Place/close perp trades on GMX v2 mainnet with accurate PnL, funding, liq in UI.

  • UI fee captured to our Safe and visible in daily reports.
  • GeoIP gate + disclaimers live; monitoring & alerts green.
  • Engagement & compensationFull-time contract (2–3 months) with option to extend/convert.
  • Competitive compensation (USD/INR) based on experience; immediate start.

    • How to apply:

    Send a DM with subject “Matrix DEX — Senior Web3 Engineer” and include:

    • GitHub/portfolio + 1–2 relevant perps/DeFi repos.
    • A short note on your GMX v2 or similar integrations (bullets).
    • Your timezone, availability, and expected monthly/weekly rate.
    • If you’ve shipped a createOrder flow (GMX v2) or a PnL/funding module before, you’ll be fast-tracked. Let’s build the cleanest no-KYC perps experience on EVM. 💥
