we’re looking for a senior blockchain engineer to build low-latency execution infrastructure around hyperevm and hyperliquid-related trading systems.
 
this is not a frontend or dapp role. the focus is on real-time execution systems, chain-native infrastructure, and market-aware backend engineering where latency, ordering, and state correctness directly impact execution outcomes.
 
you will work on systems that operate under noisy, adversarial, and highly dynamic conditions, including delayed or missing websocket events, rpc inconsistencies, transaction lifecycle complexity, state desynchronization, retries, and recovery logic.
 
core responsibilities include building and maintaining realtime blockchain data pipelines, websocket and rpc streaming systems, execution orchestration layers, liquidity-aware routing logic, transaction lifecycle management, and integration with orderbook and market data systems.
 
we are specifically looking for engineers who think in systems rather than features. meaning understanding how data flows through pipelines, how state evolves over time, how failures propagate, and how to design systems that recover automatically without manual intervention.
 
areas of work include:
 
- realtime blockchain data ingestion
- mempool-aware execution flows
- transaction lifecycle handling
- execution sequencing and routing
- websocket and rpc infrastructure
- state synchronization systems
- liquidity and orderbook integration
- performance and latency optimization
 
you should be comfortable working with distributed systems, asynchronous event processing, and latency-sensitive backend architectures.
 
strong experience in one or more of the following areas is highly relevant:
 
- exchange infrastructure
- trading systems
- execution engines
- blockchain indexers
- realtime event systems
- arbitrage systems
- rpc/node infrastructure
- defi backend systems
- low-latency backend engineering
 
preferred technical stack:
 
- typescript / node.js
- go
- rust
- python
- postgres
- clickhouse
- redis
- kafka or similar messaging systems
- docker
- linux environments
- evm rpc internals
- websocket infrastructure
 
ecosystem familiarity:
 
- ethereum, arbitrum, base, optimism, bsc
- hyperliquid / hyperevm
- foundry
- ethers.js / viem
- geth / erigon / nethermind
- dex and amm mechanics
- liquidity math, slippage, gas strategy, routing logic
 
this role is not suitable for:
 
- frontend-only developers
- nft or basic dapp experience only
- tutorial-level web3 developers
- candidates without production systems experience
 
we value engineers who have built real systems where correctness, latency, and reliability matter under load. we care less about buzzwords and more about concrete systems you have personally built and operated.
 
ideal candidates can clearly explain:
 
- system architecture decisions
- bottlenecks and tradeoffs
- failure modes and recovery strategies
- latency considerations in real systems
- production debugging experience
 
working style:
 
- remote
- async-first
- low bureaucracy
- high ownership
- engineering-driven team
- direct technical communication
 
we strongly prefer practical engineering depth over polished presentation. if you have built or worked on systems involving realtime data, trading infrastructure, blockchain execution, or latency-sensitive backend systems, please include details of those systems when applying.
 

Mission:Emit immutable trade clones at the speed of mempools. Engineer on-chain vault + relay contracts that ingest master signals, laser-bridge them across EVM chains, and absorb slippage, MEV, and NFL Sunday-level volatility without exposing followers to liquidation contagion.

Gas profiling: forge-std Vm for on-chain gas snapshots pre-per-release hook
Hard-Check Trader DNA
⚔️ You have personally executed >$10 k notional on perpetuals & on-chain or cross-margined DeFi strategies with stress traces or Etherscan proof of addr.
⚔️ You’ve felt (or caused) impermanent loss >10 % in a single block.

Responsibilities
Build gas-constrained e2e testnets atop Anvil mainnet fork for every release candidate.
Continuous white-hat review loop – both formal (Certora specs) & red-team bounty (Immunefi).
Coordinate with backend for off-chain signatures (EIP-712 typedData balancers).
Draft governance & upgrade timelocks (OpenZeppelin UUPS).
Be on-call for on-chain incidents (failed Oracle, stuck bridge, keeper tottering). with protocol parameters YAML files.
Soft Enemies – Don’t apply 
ifYou only deployed ERC-20 tokens and never** felt liquidation missiles.
You ignore MEV game theory.
Perks / Weapons Cache
Hardware fund: Apple M Max + 64 GB RAM, 10 Gbps fibre hookup.
Personal copy-trading gas allowance 1 k USD monthly – trade openly on testnet, share P&L in public.
Health stipend for red-eye debugging—includes premium dark-coffee & builder-milk.
Additional 1 % of inflation-scheduled supply upon achieving $100 m copy-AUM on ETH L2.

About the Role
We’re looking for a hands-on Growth Lead who can build early GTM systems from scratch. 
This is not a “manage a marketing calendar” role. We need someone who can identify the right ICPs, test acquisition channels, build automated growth loops, turn market feedback into product direction, and help early products reach real traction.
You’ll work directly with founders, product teams, and technical builders across Schedar-backed and incubated projects.
What You’ll Own
Define and validate early ICPs, user segments, and GTM hypotheses
Build 0-to-1 acquisition systems across outbound, community, partnerships, content, and product-led loops
Design automated growth workflows using tools like Clay, n8n, Zapier, Airtable, Notion, Apollo, scraping/enrichment tools, AI agents, or similar
Run fast experiments to identify what drives activation, retention, and conversion
Work with product and engineering teams to translate market feedback into product priorities
Build dashboards and feedback loops around growth metrics
Develop messaging, positioning, landing pages, outreach flows, and early user onboarding
Help founders understand which markets, channels, and customer segments are worth scaling
What We’re Looking For
Experience leading or executing 0-to-1 growth for early-stage startups
Strong understanding of product-led growth, GTM experimentation, and acquisition systems
Comfortable working with ambiguity, incomplete data, and fast-changing product direction
Hands-on ability to build growth workflows, not just plan strategy
Strong written communication and ability to explain complex products simply
Interest in AI, Web3, crypto, infrastructure, automation, developer tools, or fintech
Ability to work closely with technical founders and product/engineering teams
Strong bias toward execution, testing, and measurable outcomes
Nice to Have
Experience in Web3, crypto, AI, fintech, developer tools, or infrastructure startups
Experience building automated outbound or growth systems
Familiarity with tools like n8n, Clay, Zapier, Apollo, PhantomBuster, Airtable, Notion, Webflow, Framer, v0, or AI agents
Experience with community-led growth, founder-led sales, partnerships, or ecosystem growth
Prior founder, operator, or early employee experience
Understanding of wallets, protocols, DeFi, token incentives, or Web3 user behavior
You Might Be a Fit If
You like building from zero, not optimizing mature funnels
You can move between strategy and execution in the same day
You are comfortable talking to users, writing copy, building workflows, and analyzing data
You enjoy technical products and can turn complexity into clear positioning
You care about speed, ownership, and strong feedback loops
You want to work close to founders and help shape early products before they scale
Why Join Schedar
Work on multiple AI-native and Web3 products at the earliest stage
Collaborate directly with founders, engineers, and investors
High ownership and direct impact on product direction
Remote-first and flexible setup
Exposure to Schedar’s portfolio, network, and technical ecosystem
Opportunity to help build new primitives for the digital economy
Compensation
Competitive compensation based on experience, scope, and role structure. Equity/token exposure may be available depending on the specific product and engagement model.
