Join the senior team behind the Billease Android app — a Kotlin & Jetpack Compose fintech product that millions rely on for payments, credit, and secure account access. You'll own features end-to-end, raise the engineering bar alongside other senior developers, and help keep a fintech-grade codebase fast, secure, and a pleasure to work in.

 

What you'll do

• Own features end-to-end — from the networking and data layers through to pixel-accurate Jetpack Compose UI, verified in production.
• Help uphold and evolve the architecture: a clean, layered flow (data → domain → presentation), clear module boundaries, and reactive single-source-of-truth state.
• Raise the bar through rigorous code review, shared standards, and mentoring — contributing to a strong senior team, not working in isolation.
• Keep the app crash-resilient, performant, and secure — careful recomposition, disciplined null-safety, and sensitive data encrypted at rest.
• Investigate and drive production issues to root cause, then ship the fix and the regression guard.
• Help shape conventions, module design, and technical direction together with the team as the product scales.
  
  What we're looking for
  These are the bar for the role — a strong senior should meet essentially all of them, with real depth (not just exposure) in the core engineering areas.
   
  • 7+ years of professional Android development, including meaningful time in a senior or lead role owning architecture and technical decisions — not just closing tickets.
  • Expert-level Kotlin — structured concurrency with coroutines, Flow / StateFlow, strict null-safety, and a feel for clean, stable public API design.
  • Deep production Jetpack Compose: state hoisting, recomposition and performance tuning, custom layouts, and type-safe Compose Navigation at scale.
  • Command of MVVM / clean architecture and DI (Hilt/Dagger) — able to shape and uphold layering and patterns across a large codebase, not just follow them.
  • Fluent in a multi-module Gradle codebase and a disciplined Git / MR-based workflow with thorough reviews.
  • Solid REST networking (Ktor/Retrofit) and JSON serialization, local persistence (Room), and a proven security-first instinct for auth, sessions, and data at rest.
  • Fluent working from Figma — reading designs, specs, and a design-token system, and turning them into faithful, reusable Compose components in close partnership with designers.
  • Effective, judgment-driven use of AI coding tools (e.g. Claude Code, Copilot) — using them to move faster while critically reviewing and validating everything they produce to a senior's standard.
    
    The way you show up
     
    • Actively drive technical and feature discussions — asking sharp questions, weighing trade-offs, and helping the team land on the right approach.
    • Lead the charge when it counts: investigate and triage production issues, trace root causes, and drive them to resolution.
    • Take ownership end-to-end — you plan before you build, flag risks early, and see work through to verified-in-production.
    • Collaborate well in a cross-functional, fast-moving team and are comfortable with ambiguity.
      
      Nice to have
       
      • Fintech or payments experience at scale — with a security-first mindset.
      • Hands-on with data-at-rest encryption (Keystore / Tink), auth/session handling, biometrics, or KYC / liveness flows.
      • Feature-flagged delivery, analytics instrumentation, and crash monitoring.
      • Static analysis and quality gates (detekt / ktlint) and E2E UI testing.
      • Experience migrating legacy XML/Fragment screens to Compose, and contributing to a shared design system.

cubicmind-ai.com

We design our own models rather than wrapping someone else’s. That includes transformer and non-transformer architectures, built around what runs fast on edge hardware, and sometimes trained from scratch.

About the role
You will work on designing, training and optimising the models that power the device: screen understanding, action prediction and efficient on-chip inference.

This is research-heavy engineering. You will work on model architecture, training runs, attention and memory bottlenecks, low-bit compression, and getting models to run correctly on real hardware.
 

What you will do
— Design and implement new model architectures in PyTorch, both transformer-based and beyond
— Train models, sometimes from scratch, and run experiments to compare architectures
— Build training and evaluation pipelines on screen-understanding and computer-control data
— Profile latency, memory use and KV-cache behaviour on long, high-resolution screen inputs
— Compress models for edge chips using quantisation (INT8/INT4), pruning and distillation
— Export models to low-level runtimes and fix unsupported operators
— Work with our C++ team to get models running efficiently on the device

 

Requirements

— Deep architectural understanding of Transformers and Attention: you know the mathematical and operational differences between MHA, MQA, GQA, FlashAttention, and linear attention variants; you understand KV-cache scaling and memory access bottlenecks.

— Low-level PyTorch fluency: writing custom PyTorch modules, implementing non-standard forward/backward logic, vectorised tensor operations

Why this role exists:

This role exists to protect our financial flows and optimize payment health in real time. You’ll help us minimize fraud exposure and operational friction by owning end-to-end payment processing analysis, deposit/withdrawal risk decisions, and transaction monitoring.

What you’ll drive:

Risk Analysis & Transactional Decision-Making

• Analyze full transactional flows across deposits, withdrawals, and payment histories to spot anomalies, suspicious behavior, and operational errors.
• Review high-value and high-risk transactions in real time, making firm, evidence-based approve/decline decisions to control financial exposure.

• Identify payment fraud indicators, potential chargeback risks, payment method abuse, and mismatches between deposit sources and withdrawal destinations.

   

Operational Execution & Case Management

• Investigate complex payment cases involving failed, pending, unusual, or declined transactions across various payment methods.
• Manage multiple urgent cases simultaneously, using risk severity and potential financial impact to set priorities.

• Maintain clear, structured, and audit-ready documentation for all reviewed cases, decisions, and risk actions.

   

System Optimization & Feedback

• Distinguish root causes quickly among genuine payment fraud, platform configuration gaps, gateway technical failures, or provider-side issues.
• Identify operational friction, missing rules, or system logic gaps and submit structured feedback to improve risk tool setups.

• Respond immediately to operational spikes and risk incidents without sacrificing accuracy or thoroughness.

   

Stakeholder & Cross-Team Collaboration

• Communicate transactional findings, decisions, and necessary interventions clearly to Finance, Support, Tech, and Fraud teams.

• Follow cases through to full resolution, taking clear ownership and escalating complex scenarios promptly when higher authorization is required.

   

What makes you a GR8 fit:

Must-have:

• 1+ years of hands-on experience in payment operations, transaction monitoring, billing, fraud prevention, or risk operations (FinTech/iGaming/E-commerce).
• Practical knowledge of transactional risk analysis, deposit/withdrawal flows, transaction statuses, and chargeback exposure.
• Proven experience working with alert-based risk consoles, analytical tools, or payment back-office systems in high-volume environments.
• Strong ability to multitask and prioritize urgent, high-value alerts based on financial impact.
• Decisive judgment with the confidence to execute fast, high-stakes decisions under pressure.
• Clear cross-team communication skills to explain complex risk rationale concisely.
• Upper-Intermediate English level for clear, structured cross-team communication and audit documentation.

• Readiness to work in a rotating shift schedule, including night shifts.

   

Nice-to-have:

• Experience working with alternative payment methods (APMs) and crypto payment rails across different regions.
• Understanding of basic SQL or advanced Excel/data tools for quick pattern searching.

• Prior experience dealing with payment service providers (PSPs) and acquiring banks directly.
