Our infrastructure powers 70% of the top web3 teams, 90%+ of web2 companies building in web3 and 100+ million end users. Our customers include top web3 brands like Polymarket, OpenSea, Circle, WorldCoin, as well as major global brands like Shopify and Adobe.

The Alchemy team draws from decades of deep expertise in massively scalable infrastructure, AI, and blockchain from leadership roles at leading companies and universities like Google, Microsoft, Facebook, Stanford, and MIT.

We're backed by the world's leading VCs and institutions, including: Lightspeed, Silver Lake, a16z, Coatue, Pantera, Addition, Stanford University, Coinbase, and Charles Schwab, among others.

The Role

Alchemy builds the infrastructure that the largest financial institutions in the world depend on. The Transaction Engine team owns the systems that power gasless transactions that land on-chain reliably, predictably, and at scale.

This role is for a Senior Backend Engineer who wants to shape core transaction infrastructure, influence platform direction, and operate at the intersection of backend systems and on-chain execution. 

You’ll define and evolve the systems that handle transaction submission, simulation, tracking, and debugging across chains. Your work will directly affect transaction success rates, developer trust, and platform reliability.

You’ll operate at platform scale, with real usage, real constraints, and real outcomes.

What You'll Do:

  • Set technical direction for core transaction and wallet-adjacent backend systems.
  • Design and evolve APIs used by external developers and internal product teams.
  • Lead architecture decisions around scalability, correctness, and operational resilience.
  • Partner with product, infra, and protocol teams to drive multi-quarter initiatives.
  • Raise engineering standards through design reviews, mentorship, and technical leadership.

What We're Looking For:

  • 7+ years of relevant industry experience
  • BS/BA degree in Computer Science
  • Senior level backend engineering experience operating large production systems.
  • Strong proficiency in Java, TypeScript, and/or Rust.
  • Proven track record designing durable, widely-used APIs.
  • Strong understanding of smart contract execution:
    • Comfort reading ABIs, logs, traces, and transaction receipts
    • Ability to reason about on-chain behavior without writing Solidity
  • Experience leading complex technical projects across teams.
  • Clear ownership mindset and high technical judgment.
  • Web3 experience, a plus
