Join us as an Quantitative Researcher. 

Requirements:

Education & Experience:

— MSc or PhD in a quantitative field; a live trading track record outweighs credentials

— 5+ years in quantitative research or trading at a top-tier HFT firm, market maker, systematic fund, or crypto-native market maker; exchange-side market-structure experience is a plus

— Hands-on experience with at least one TradFi asset class (FX, futures, equities) and / or equivalent crypto asset classes; both maker and taker strategies

Core Technical Skills:

— Advanced probability, statistics, time-series analysis, optimization; strict validation discipline (multiple testing, out-of-sample hygiene, live–sim parity)

— Market microstructure: order-book dynamics, queue position, fill probability, adverse selection and markouts, market impact

— Expert Python (NumPy, pandas/Polars, PyTorch); working C++ or Rust for latency-critical components

— Tick-data engineering at scale: columnar stores, cross-venue normalization, data-quality control

Market Knowledge:

— Crypto microstructure: CEX matching engines and fee schedules, perpetuals (funding, mark price, liquidation/ADL), cross-venue arbitrage, DEX/AMM basics

— TradFi microstructure: FX ECN mechanics (firm vs last-look liquidity, prime brokerage), listed futures; low-latency architecture (tick-to-trade path, colocation, exchange protocols)

— Inventory and hedging: quoting models of the Avellaneda–Stoikov class and extensions, multi-asset inventory optimization, hedging, settlement workflows, real-time risk limits and kill switches

Exchange Microstructure & Mechanism Design:

— Maker-taker economics and market-quality measurement: fee-tier and rebate architecture, per-segment elasticity, spread/depth/slippage/markout metrics, defenses against rebate farming and wash trading

— Liquidity program design: obligation-based schemes (two-sided quoting, presence at touch, minimum depth, uptime) and incentive-based schemes (tiered rebates, credit lines, connectivity benefits)

— Maker protection and flow segmentation: markout-based counterparty scoring, retail price improvement (RPI) order types, asymmetric speed bumps and latency floors, minimum quote life, self-match prevention

— Exchange P&L modeling: net fee capture, subsidy budget and payback, LP unit economics from onboarding to self-sufficiency

Mindset & Soft Skills:

— Owner mentality with direct P&L accountability; ships to production and makes honest kill decisions

— Clear written communication with traders, engineers, exchange management, and external LPs

— Compliance discipline across crypto and TradFi market-abuse regimes

Responsibilities:

Responsibilities — Liquidity Program:

— Design the program end-to-end: MM tiers, admission criteria, obligations (max spread, min depth, uptime, presence at touch), incentives, and graduation to subsidy-free self-sufficiency

— Optimize the fee schedule for net capture: taker tiers priced to measured elasticity by segment; maker rebates funded from taker fees; safeguards against tier gaming

— Design order-book mechanics for comfortable quoting: tick and lot sizing, post-only / iceberg / RPI order types, self-match prevention, minimum quote life, passive-liquidity protection options

— Build the toxic-flow framework: markout-based flow classification, counterparty scoring, continuous monitoring, access rules or surcharges for consistently toxic takers

— Own the program financial model and roadmap: subsidy budget with payback targets; phases bootstrap → organic profitability → self-sufficiency; a market-quality dashboard as the single source of truth

Responsibilities — Trading Desc:

— Own the strategy roadmap — crypto first, then TradFi FX and futures; design pricing, quoting, hedging, and execution as one portfolio

— Run end-to-end alpha research on tick/order-book, cross-venue, funding/basis, and on-chain data

— Design the inventory-aware hedging framework, portfolio risk limits, and parameter governance

— Partner with engineering on low-latency implementation; validate in high-fidelity simulation and canary deployments

— Own P&L attribution, TCA/markout analysis, and research standards

🎰 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.
