Card-present acceptance on phones
Tap2Mobile SoftPOS runs on Android devices used by real merchants. Teams own device telemetry, transaction state, acquirer context, and bank integration boundaries.

Firisbe teams ship PCI-certified infrastructure for banks, PSPs, acquirers, and fintechs. The work spans card acceptance, orchestration, risk, operations, and evidence, with production ownership from the first quarter.
Teams work on regulated payment systems with real throughput, live bank traffic, and audit evidence that has to stand up every year.
Most work starts from a live payment surface, not a blank canvas. You improve the path from device to acquirer, then make the evidence useful for operators and auditors.
Tap2Mobile SoftPOS runs on Android devices used by real merchants. Teams own device telemetry, transaction state, acquirer context, and bank integration boundaries.

Routing, fallback, provider health, cost rules, and settlement preferences sit in the orchestration layer. A small change can affect authorization quality at production scale.

Support, risk, finance, and compliance use the same logs, dashboards, exports, and audit trails. Engineering work is not done until the operator can explain what happened.

We hire around operating boundaries rather than generic departments. If your work touches correctness, uptime, risk, or partner outcomes, there is probably a useful conversation to have.
Authorization flows, ledger-adjacent services, provider integrations, webhook contracts, reconciliation exports, and internal APIs.
Android Tap to Phone surfaces, SDK integration quality, merchant app reliability, receipt flows, device signals, and field diagnostics.
PCI evidence, transaction monitoring, KYC handoffs, access reviews, incident timelines, and audit-ready operating controls.
Bank and PSP launches, sandbox enablement, migration planning, production readiness, and technical account ownership.
Observability, incident response, capacity planning, release discipline, runbooks, and the boring work that keeps payments moving.
Admin surfaces, operator workflows, documentation, internal tools, and the web systems that make complex payment work legible.
Firisbe is a small enough team for direct ownership and a regulated enough environment for careful engineering habits to matter.
Teams are accountable for a clear surface, such as SDK state, routing health, reconciliation, support tooling, or audit evidence.
Engineers sit close to support, risk, finance, and partner teams so product decisions are tested against real production work.
PCI scope, MPoC controls, and QSA evidence are taught through reviews, shadowing, and live procurement conversations.
Design notes, runbooks, dashboards, and audit trails are treated as part of the feature, not cleanup after launch.
Maslak office days are for design reviews, launch rooms, incident work, and partner sessions. Focus work can stay quiet.
Offers are calibrated for the Turkish market with private health coverage and equity for roles that carry long-term ownership.
The signal we look for is production judgement: how you debug, make tradeoffs, communicate risk, and leave systems easier to operate.
Thirty minutes with the hiring manager to understand your work, the role boundary, and what you want to build next.
A practical session around a payment or systems problem. No brainteasers, no whiteboard theatre, no unpaid project week.
Meet future teammates across engineering, product, or operations. You evaluate the team as much as the team evaluates you.
If there is a fit, we send a written offer with salary, equity, benefits, hybrid expectations, and start-date options.
Short answers for candidates considering engineering, risk, operations, product, or partner-facing roles.
Send a short note, links to relevant work, and the boundary you want to own. A Firisbe hiring manager will route it to the right team.
