Sidechain is a talent platform connecting you with vetted fintech and payments engineers who've built production financial systems, a faster alternative to a fintech recruiter or recruitment agency.
Fintech engineers build the infrastructure behind digital financial services: payment processors that handle millions of transactions per day, banking APIs that connect to legacy core systems, trading platforms that execute orders in microseconds, and compliance systems that detect fraud and meet regulatory requirements.
Beyond transaction processing, they design ledger systems that maintain accurate balances, build reconciliation workflows that catch discrepancies, implement KYC and AML checks, integrate with card networks and ACH, and create reporting tools for finance and operations teams. The role demands understanding of both modern distributed systems and legacy financial infrastructure.
In practice, fintech engineering spans backend systems for payment processing and account management, integration with banking partners and payment networks, security and compliance tooling, data pipelines for financial reporting, and customer-facing APIs. Reliability and accuracy are non-negotiable when handling real money.
Many teams hire engineers with general backend experience when they need financial systems expertise. Building fintech is fundamentally different from building e-commerce or social apps. Transactions must be idempotent, ledgers must balance to the penny, and compliance failures have legal consequences. Look for engineers who've worked with real money and understand financial primitives.
Another mistake is underestimating regulatory complexity. Every payment flow touches multiple regulations: KYC, AML, OFAC sanctions, PSD2, GDPR, card network rules, and banking partner requirements. You need engineers who've navigated compliance workflows, implemented audit trails, and maintained certifications like PCI-DSS or SOC 2.
Finally, many companies overlook operational maturity. Fintech systems must handle edge cases: failed payments, partial refunds, currency conversion, timezone handling, and reconciliation discrepancies. The best engineers think about failure modes, implement robust retry logic, build monitoring for financial anomalies, and design systems that can be audited.
We're a curated talent platform for fintech recruiting, not a job board. Instead of sifting through generic applications, you tell us your requirements and we introduce a tailored shortlist of pre-vetted fintech engineers from our network of 1,500+ engineers.
Every engineer has been screened on their previous work and shipped projects, background and references, communication skills, and culture fit. We evaluate real systems: payment platforms they've built, banking integrations they've completed, and compliance workflows they've implemented. Only the top 3% make it through our vetting process.
Most clients receive their shortlist within 5-7 days and complete a hire within 1-2 weeks. We support both contract and full-time placements. You pay nothing until you hire, with success-based fees and no retainers. If a hire leaves within 90 days for reasons unrelated to company performance, we provide a one-time replacement at no additional fee.
Look for engineers who understand financial systems, regulatory requirements and production infrastructure at scale. The best fintech engineers have shipped payment systems, know how money moves through banking networks, understand compliance and KYC workflows, and can reason about edge cases involving real transactions and real money. Domain knowledge matters as much as technical skill.
Most clients receive a tailored shortlist within 5-7 days. Our network includes engineers with experience across payment processing, banking infrastructure, trading platforms and financial APIs, so we can move at your pace.
Both. Whether you need an engineer to build a payment API, integrate banking rails, or join your team permanently, we support contract and full-time placements.
We back every placement. If a hire leaves within 90 days of their start date for reasons unrelated to company performance, we provide a one-time replacement at no additional fee.
Nothing until you hire. We charge a success-based fee only once you've made a placement. No upfront costs, no retainers.
