🎰 Senior Java Engineer: Build the Wallet Behind Millions of Players

Adaptiq × a major online gaming operator

The challenge:

Picture a platform where millions of players hit "play" at the same moment, every action moves real money, and the answer must come back in under a second. Now picture building it from scratch.

That's the PAM (Player Account Management) platform: real-time financial transactions, strict regulation, zero tolerance for lost cents, and traffic spikes that would make most systems sweat. No legacy code to inherit. Just a blank page and hard problems.

Your role:

You'll design and build the core backend of the platform and own your features end-to-end: from RFC to production monitoring. You'll work side by side with Principal Engineers, with real autonomy and real influence on the architecture.

What you'll do:

• Build services in Java 17+ / Spring Boot for wallets, ledger, payments, bonuses, and account state
• Create REST APIs and Kafka-based event flows for frontends, ops tools, and partners
• Make correctness non-negotiable: idempotency, clear transaction boundaries, failure handling, solid testing
• Bake in compliance: KYC/AML, responsible gaming, audit trails
• Keep production healthy with metrics, tracing, alerts, and on-call
• Shape the platform through RFCs and code reviews, and mentor teammates
• Work with AI-assisted tools daily

• Help migrate live from the existing third-party platform (parity testing, data validation, cutover)

   

What you bring:

• 5+ years in backend engineering, with strong Java 17+ and Spring Boot
• Experience with high-integrity transactional systems: payments, wallets, billing, banking, e-commerce, or gaming
• Deep PostgreSQL (or similar) knowledge: schema design, ACID, locking, tuning
• Event-driven architecture experience (Kafka, RabbitMQ), including idempotency and retries
• Automated testing as a habit: unit, integration, contract
• Hands-on production experience with containers, CI/CD, observability, and incident troubleshooting
• Solid grasp of multi-threading and fault-tolerant design

• Good English and comfort working across time zones

   

Bonus points:

✦ iGaming, betting, or fintech background
✦ Kubernetes and AWS (VPC, IAM, EKS, auto-scaling)
✦ Compliance-driven development experience
✦ Agentic development workflows
 

If you want your code to handle real money, real scale, and real responsibility, let's talk.

Do you work with bare-metal C/C++ and embedded algorithms where every millisecond and byte of memory matters? A team developing interceptor drones has opened an office in central Vilnius and is looking for an Embedded Radar Engineer to work with radar algorithms, SoC, FPGA/DSP, and RTOS.

We build miniature radar seekers. You have to extract small, low-RCS drone tracks from heavy background clutter, EW interference, and motor noise. You have to run this math on severely constrained silicon. You are bound by strict compute, memory, and thermal limits. The processing loop must close in milliseconds. There is no cloud, no heavy GPU, and no room for inefficient code.

Main Responsibilities

You own the math and the metal. You design the radar algorithms (FMCW, CFAR, beamforming, MIMO virtual arrays) and the advanced tracking math (Kalman filters, multi-target tracking, clutter rejection). You implement this across the SoC architecture – managing the heavy lifting on FPGA and DSP accelerators and writing the bare-metal C or RTOS code for the microcontrollers. You manage the memory architecture, the DMA transfers straight from the ADCs, and the low-level peripheral drivers. You also own the data handoff, packaging clean point-clouds and track histories for our Edge ML classification models.

PROOF OF EXECUTION
Degrees do not matter here. We want to see the algorithms you have built AND physically deployed on embedded hardware. If you only simulate perfect radar returns in MATLAB and have never managed a memory buffer or a DMA transfer, do not apply. Show us how you squeezed complex tracking math into a constrained chip (FPGA, RFSoC, or MCU) without blowing up the latency. We expect you to take raw field data on a Tuesday, rewrite the algorithm, and flash a new firmware image to the seeker on a Thursday.

Mandatory Requirements

You must work in our Vilnius lab every day. We go from the bench to field testing in days, not months. The financial package includes a top-of-market base salary, founding equity, a relocation bonus, company housing, and a daily allowance. We cover all logistics and remove all friction so you can focus 100% on building hardware.

We offer

This role requires your daily physical presence in our Vilnius lab. We move from the test bench to live field validation in days, not months. We provide a top-of-market base salary, founding equity, a relocation bonus, company housing, and a daily allowance. We remove all financial and logistical friction so you can focus entirely on shipping hardware.
