FinTech · PCI-DSS-aware · FCA-aware · KYC/AML

Hire FinTech app developers. PCI-DSS-aware, FCA-aware senior talent.

Senior FinTech engineers — payments, KYC, AML, customer-due-diligence, PCI-DSS-aware backends, 3DS2/SCA — into your team in 14 calendar days. FinTech apps are not “apps that handle money”; they are apps that handle money under audit. The engineers we deploy have shipped this stack in production, not configured it from a tutorial.

Rates run $32/hr mid-level to $58/hr architect, against US senior FinTech rates of $90–$160/hr. PCI-DSS-aware design, FCA-aware for UK fintech, SOC 2-aware for B2B.

Why eCorpIT

Why hire FinTech developers through eCorpIT.

FinTech apps handle money under audit. KYC and AML flows that survive FCA, RBI, MAS or US state-banking review. PCI-DSS-aware data handling that never stores card data on device. Customer-due-diligence audit trails that survive a regulator’s data-subject request. Cryptographic key management that doesn’t leak through observability tooling. Tokenisation, fraud signals, dispute and chargeback flows.

Manu Shukla reviews every FinTech engagement at architecture and milestone stages. The engineer whose CV you interviewed is the engineer who ships.

US seniors $90–$160/hr
UK seniors £50–£95/hr
eCorpIT $44–$48/hr (senior)

A 60–70% vs US specialists saving at the same seniority, on a dedicated pod with an MSA and DPA signed before code is written. Industry rate benchmarks.

  • PCI-DSS-aware by default

    Card data never touches your servers — Stripe Elements, Adyen tokenisation, or Apple Pay / Google Pay as the acceptance layer. Server-side handling restricted to tokens. No card PANs in logs, no plaintext in databases, no card data on device.

  • KYC, AML & CDD flows

    Document capture (CameraX edge-detection, Vision framework), liveness checks, sanctions-screening API integrations, ongoing-monitoring webhooks. Shipped for UK FCA-regulated clients and US payment processors.

  • SCA & 3DS2

    Required for EU/UK payment flows under PSD2/PSD3. Senior engineers who understand the SCA exemption matrix beat juniors who treat 3DS as one library call.

  • FCA-aware UK fintech

    Shipped UK fintech apps with KYC, AML, CDD and operational-resilience flows that survived FCA-regulated client audits. We don’t claim “FCA approved” — only the regulated firm can be — but we design to make the audit straightforward.

  • Multi-PSP architecture

    Stripe, Razorpay, Adyen, Plaid; BNPL (Klarna, Affirm); KYC SDKs (Onfido, Sumsub, Jumio). Dispute and chargeback flows. India: UPI 2.0, RBI tokenisation, video-KYC.

  • Secure-by-construction

    Secure enclave usage, EMV tokenisation, OWASP MASVS Level 2 design, PCI-DSS scope-reduction architecture. PSP sandbox only in development — no real card data ever lands in dev or staging.

Transparent pricing

FinTech rate card (USD, hourly).

Same rate card as the umbrella hire page. FinTech work is typically staffed at the Senior or Lead tier given the regulatory exposure; Junior FinTech engineers rarely work without senior pairing on regulated workloads. All-in, weekly invoicing, net 14.

Tier Experience Flutter / RNiOSAndroid
Junior 1–2 years $22/hr$24/hr$22/hr
Mid-level 3–5 years $32/hr$35/hr$32/hr
Senior 6+ years $44/hr$48/hr$44/hr
Lead / Architect 8+ years $58/hr$62/hr$58/hr

For a typical UK-bought fintech MVP at 160 hours/month with one Senior plus shared PCI-DSS-aware backend support, that is about $42K eCorpIT versus $108K at the US senior midpoint. Same regulatory comfort, same shipped app.

How you work with us

Four engagement models.

You pick the one that fits how you actually want to work. We do not push everyone into the same shape.

Hourly

True Time & Materials

Weekly invoicing, minimum 40 hours per month, weekly demos. You pay only for the hours we log against your project board. Best for fintech maintenance, regulatory-driven updates, or short technical spikes.

Monthly

Dedicated developer · 10% off

160 hours per month, dedicated. 10% discount on the hourly rate. The engineer attends your standups, sits in your Slack, follows your sprint cadence. Pause with 30 days’ written notice. Best for active builds.

Quarterly

Pod · 480 hours · 15% off

3-month commit, 15% discount on hourly. Includes a shared designer (40 hours) familiar with payment flows and a shared QA engineer (40 hours) at no additional cost. The pod model — a real team behind one engineer.

Project

Fixed scope · fixed price · fixed timeline

$15K (fintech-aware) MVP starting (a small premium over the $8K cross-platform start because regulatory overhead is real). We own scope, milestones and acceptance criteria. Weekly demos, weekly invoicing against milestones. Best when the spec is well-defined and you want predictability.

All four models include the NDA signed before any technical conversation, an MSA with India and EU/UK-aligned clauses, a DPA aligned with GDPR and India’s DPDP Act, weekly invoicing, and a single named delivery lead for the whole engagement. PCI-DSS-aware delivery from Sprint 1.

Answers, up front

How much does it cost to hire fintech app developers?

eCorpIT senior fintech engineers bill $22–$58/hour by seniority — about 60–70% below US cost — with PCI-DSS-aware (and FCA-aware) delivery, KYC/AML and payments integration. The regulated overlay adds hours, but the rate base keeps a compliant build well below US-agency pricing.

What should I look for in a fintech app developer?

Look for PCI-DSS-aware architecture, KYC/AML flows, secure payments and ledgering, and — for UK fintech — FCA-aware documentation. eCorpIT matches senior engineers who have shipped regulated financial apps, with the audit and security scaffolding designed in, not bolted on.

FAQ

Questions, answered.

What US and UK teams ask before hiring FinTech developers with us.

Do you handle PCI-DSS-aware fintech development?
Yes — tokenisation, scope-reduction architecture, no-PAN-on-device design, audit-trail patterns. We are not ourselves PCI-DSS certified as an entity — the merchant-of-record is the regulated firm. We make the client’s audit straightforward.
Can you build for FCA-regulated UK fintech firms?
Yes — we have shipped UK fintech apps with KYC, AML, CDD and operational-resilience flows that survived FCA-regulated client audits. We don’t market as “FCA approved” — only the regulated firm can be.
What are your fintech rates vs a US specialist agency?
eCorpIT senior rate is $44–$48/hour. US fintech-specialist agencies bill $90–$160/hour at the same seniority. Arbitrage is 60–70% on like-for-like work.
Do you integrate with Stripe, Razorpay, Adyen, Plaid, Onfido, Sumsub?
Yes — multi-PSP architecture is standard. Our senior engineers have shipped each integration into production for US, UK and Indian clients.
Can you ship 3DS2 / SCA for EU and UK payments?
Yes — the PSD2/PSD3 SCA exemption matrix is standard knowledge, not a research exercise. We have shipped SCA-compliant flows for FCA-regulated UK fintech clients.
Do you handle KYC and AML for the Indian RBI regime?
Yes — UPI 2.0, RBI tokenisation, video-KYC, Aadhaar-based KYC (where authorised), and CKYCR integration for Indian neobank and NBFC clients.
How do you protect customer financial data during development?
PSP sandbox environments only during development. No real card data ever lands in dev or staging. Synthetic data for test fixtures. Production data access restricted to the customer’s deployment.
Who actually writes the code?
The engineer whose CV you interviewed. No bait-and-switch, no junior backfill on regulated workloads.
