About DCS Card Centre
DCS Card Centre is a financial payments and Web3 company building at the intersection of AI agents and on-chain payments. We are hiring a Senior Smart Contract Engineer to design and implement the on-chain contracts and protocol integrations that enable autonomous payments by AI agents.
This is a deeply technical role focused on stablecoin settlement, on-chain authorization, agent identity, trusted machine-to-machine transactions, and secure payment infrastructure. You will write secure, gas-efficient, auditable Solidity code that may directly handle real value. Contract safety, code quality, and risk awareness are the highest priorities.
What You Will Work On
Design, develop, and test core payment smart contracts for stablecoin settlement, escrow/clearing, on-chain authorization, subscriptions, and usage-based billing.
Build reusable Solidity components and engineering standards for secure, gas-efficient, and audit-ready contracts.
Implement security best practices, including reentrancy protection, access control, integer safety, permission boundaries, upgrade risk review, and audit remediation.
Integrate emerging agentic payment protocols such as x402, AP2, ERC-8004, and related standards.
Build the on-chain identity, payment authorization, and stablecoin settlement loop for AI agents.
Contribute to multi-chain and L2 payment infrastructure, batch settlement, gas optimization, and stablecoin payment rails.
Work closely with backend, product, and risk teams to safely connect on-chain capabilities to production business flows.
Requirements
3–5 years of smart contract or blockchain engineering experience. Strong candidates with exceptional project experience are also welcome.
Strong Solidity expertise and hands-on experience shipping production smart contracts.
Deep understanding of the EVM, gas optimization, and common Solidity frameworks such as Foundry or Hardhat.
Strong smart contract security mindset and familiarity with common vulnerabilities and audit workflows.
Experience with at least one major EVM ecosystem such as Ethereum, Base, BNB Chain, or other L2 networks.
Experience in stablecoins, payments, DeFi, clearing/settlement, or other financial smart contract systems.
High ownership mindset and strong sensitivity to fund safety and production risk.
Nice To Have
Experience with agentic payment protocols such as x402, AP2, MPP, or ERC-8004.
Smart contract audit or formal verification experience with tools such as Slither, Echidna, Certora, or similar.
Experience with stablecoin payments, cross-chain settlement, or account abstraction such as ERC-4337.
Familiarity with AI Agent, MCP, A2A, or related agent technology stacks.
Rust or Move smart contract experience.

About the Role
We’re looking for a hands-on Business Development Manager who can help Schedar build strategic relationships across the AI, Web3, crypto, infrastructure, and startup ecosystem.
This is not a “send cold messages and collect logos” role. We need someone who can identify high-value founders, protocols, funds, ecosystem partners, communities, infrastructure providers, KOLs, accelerators, and technical teams — then turn those relationships into real opportunities for collaboration, deal flow, partnerships, talent, and growth.
You’ll work directly with Schedar’s team, founders, portfolio-related projects, and external ecosystem partners to expand Schedar’s network and support early-stage AI-native and Web3 products.
What You’ll Own
Identify and source high-potential startups, founders, projects, protocols, and ecosystem partners across AI and Web3
Build relationships with founders, operators, investors, accelerators, developer communities, protocol ecosystems, KOLs, and strategic partners
Create and manage outbound BD pipelines across LinkedIn, Telegram, X, email, Discord, events, and founder communities
Support Schedar’s deal flow by discovering early-stage AI-native and Web3 projects that may be relevant for investment, incubation, or collaboration
Build partnership opportunities for Schedar-backed and incubated projects
Map key ecosystems, communities, events, accelerators, grants programs, and founder networks
Qualify inbound and outbound leads based on relevance, stage, traction, team quality, technical depth, and strategic fit
Coordinate intro calls, follow-ups, partner conversations, and relationship tracking
Maintain CRM hygiene and structured notes on founders, projects, partners, and opportunities
Work with product, growth, recruiting, and investment teams to turn ecosystem relationships into actionable outcomes
Help represent Schedar in online communities, events, founder groups, and partner conversations
What We’re Looking For
Experience in business development, partnerships, ecosystem growth, venture scouting, startup operations, community, sales, or founder relations
Strong interest in AI, Web3, crypto, blockchain infrastructure, developer tools, automation, fintech, or frontier technology
Ability to identify high-signal people, projects, and communities before they become obvious
Comfortable doing direct outreach and building relationships from scratch
Strong communication skills and ability to explain Schedar’s value clearly to founders, partners, and technical teams
Ability to qualify opportunities, ask good questions, and understand what makes a project strategically relevant
Comfortable working in a fast-moving, ambiguous, remote-first environment
Strong follow-up discipline, CRM organization, and ownership over relationship pipelines
Ability to move between strategy and execution in the same day
High agency, curiosity, and bias toward action
Nice to Have
Existing network across Web3, AI, crypto, venture, startup, developer, or founder communities
Experience working at a VC fund, accelerator, startup studio, crypto exchange, protocol foundation, or early-stage startup
Understanding of DeFi, wallets, L1/L2 ecosystems, infrastructure, token incentives, on-chain analytics, decentralized compute, or AI agents
Experience with tools like Notion, Airtable, HubSpot, Attio, Clay, Apollo, Telegram, Discord, X, LinkedIn, or similar
Experience sourcing startups, founders, investment opportunities, or strategic partnerships
Experience organizing founder intros, ecosystem collaborations, demo days, events, or community partnerships
Ability to write clear outreach messages, partner briefs, founder notes, and follow-up summaries
Multilingual ability or strong network in Asia, Europe, MENA, or global Web3 markets is a plus
You Might Be a Fit If
You enjoy building relationships before there is a clear playbook
You can spot strong founders and interesting technical projects early
You are comfortable talking to founders, investors, developers, community leads, and ecosystem partners
You don’t just network — you turn conversations into structured next steps
You understand that BD in early-stage ecosystems is about trust, timing, relevance, and follow-through
You are curious about AI-native products, Web3 infrastructure, decentralized compute, developer tools, and new digital primitives
You like working close to founders and helping early products find the right partners, users, investors, and talent
You care about speed, ownership, and measurable relationship outcomes
Why Join Schedar
Work at the intersection of AI, Web3, venture capital, and early-stage company building
Collaborate directly with founders, technical builders, investors, and ecosystem leaders
High ownership over Schedar’s partnership and ecosystem development
Remote-first and flexible setup
Exposure to Schedar’s portfolio, network, and technical ecosystem
Opportunity to help discover and support new primitives for the digital economy
Build relationships across some of the most interesting AI-native and Web3 communities globally
Compensation
Competitive compensation based on experience, scope, and role structure. Performance-based incentives, success-based bonuses, equity/token exposure, or project-based upside may be available depending on the specific engagement model.

Hands-on experience using crypto products such as wallets, CEXs, DeFi apps, or on-chain tools
Experience with developer tools, APIs, SDKs, infra, or technical products
Experience working with early-stage startups or venture studios
Familiarity with tools like Notion, Linear, Jira, Figma, Airtable, Slack, Discord, Telegram, or CRM systems
You Might Be a Fit If
You like building products from zero rather than optimizing mature systems
You can move between strategy and execution quickly
You enjoy working directly with founders and technical teams
You can simplify complex technical ideas for real users
You care about user behavior, activation, retention, and product-market fit
You are excited by AI-native and Web3 products
You are comfortable with stealth products and fast-changing priorities
