Built on Solana, our platform delivers deterministic execution, guaranteed inclusion, and low-latency performance—solving the foundational failures that cause transactions to miss, trades to revert, and systems to collapse under pressure. By placing high-performance compute close to where transactions happen and coordinating execution through our advanced scheduling engine, Raiku empowers developers to build scalable, high-performance applications—and gives institutions the reliability and control they demand. We believe financial infrastructure should behave like physics: fast, reliable, and predictable—every time, without exception. ### The Role As a **Senior Validator Engineer** at Raiku, you will spearhead our engineering efforts surrounding the Solana Validator (both Agave and Firedancer), driving the innovation and implementation of next-generation high-performance distributed systems.

## The Role We’re looking for a **senior backend engineer** to own and evolve the core backend systems that power: * Protocol and pool indexing * Portfolio and allocation logic * Execution planning and transaction orchestration * Safety, constraints, and failure handling You’ll be working closely with the founder (product/system design) and will have **real ownership** over architecture and technical decisions. This is not a CRUD role. It is a **decision + execution system**. ## What You’ll Work On * Design and implement backend services that: * Ingest and normalize on-chain protocol data (pools, yields, constraints) * Represent pools, allocations, and execution plans as deterministic data structures * Build allocation and constraint logic (risk caps, concentration limits, eligibility filters) * Own execution planning: * Swaps, deposits, sequencing * Batching vs multi-tx flows * Simulation and preflight checks * Implement robust failure handling: * Partial execution * Slippage errors * Protocol unavailability * Collaborate on agent boundaries: * What is deterministic vs flexible * What the system is allowed vs forbidden to do * Help shape monitoring and post-execution state tracking ## What We’re Looking For **Required** * 5+ years of backend engineering experience * Strong system design instincts (you think in invariants, edge cases, failure modes) * Experience building production systems that interact with external, unreliable dependencies * Comfort working in ambiguous, early-stage environments * Strong opinions, weakly held **Strong Plus** * Experience with blockchain or DeFi systems (Solana preferred) * Experience with financial systems, trading, or risk-sensitive software * Familiarity with transaction orchestration, batching, or execution pipelines * Experience designing schemas and APIs that must remain stable over time ## AI Scope AI is used to interpret user intent and generate explanations - not to predict markets or autonomously move funds. You’ll help define clear interfaces and guardrails between AI outputs and backend execution logic. ## What This Is *Not* * Not a growth-hacking role * Not a UI-heavy role * Not “just integrate APIs” * Not a hype-driven AI project If you enjoy thinking about **what must never happen** as much as what should happen, you’ll like this role. ## How We Work * Non-custodial, safety-first mindset * Product clarity > feature velocity * Explicit constraints and contracts * Honest communication about what’s unfinished * Small team, high trust, real ownership The founder does not code and is very intentional about hiring senior engineers who care about correctness, architecture, and long-term product integrity.

## About Us Bullet is building a cutting-edge decentralized perpetuals trading platform on Solana. Founded by a team from HFT, Silicon Valley tech, and crypto exchanges. Backed by Electric Capital, Jump Capital, Race Capital, Wintermute, and others. We previously built Zeta Markets, one of the top perpetual DEXs on Solana with over $15B in volume traded in 2025. Bullet is the next step: 500µs trade execution latency, 10k+ transactions per second, full-featured perps and spot DEX for pros and retail. ## The Role We need a senior frontend engineer who can own large features end-to-end. You'll work with design and product to define solutions to ambiguous problems, then ship them. Small, results-driven frontend team. We care about product quality and execution speed. **What You'll Do** - Own features from technical design through production - Build and maintain Bullet's trading UI in React, TypeScript, and Next.js (App Router, Server Components, Server Actions) - Ship fast, polished interfaces for trading, portfolio management, and onboarding. Desktop-first, with mobile web and some React Native work. - Make tradeoffs between speed and quality. Know when to ship and when to polish. - Work across the stack when needed. We're frontend-focused but you should be comfortable touching APIs and some infrastructure. - Participate in code reviews. We take this seriously and expect thoughtful review of others' code, not just rubber stamping. - Communicate clearly verbally and in writing. Good async communication helps depending on timezone overlap. ## Requirements - 5+ years building production React applications - Deep experience with Next.js (App Router preferred), including SSR, SSG, ISR, Server Actions, and API routes - Ability to create clean abstractions: reusable components, custom hooks, shared utilities that work across desktop and mobile - Solid grasp of frontend performance optimization, animation, and state management - Comfortable working across the full stack when needed - Experience with financial interfaces, trading dashboards, or data-heavy applications (or genuine interest) - Sharp eye for design and detail - Familiarity with analytics, error tracking, and deployment tools (Amplitude, Sentry, Vercel) **Bonus** - Fintech, crypto, or trading UI experience - Charting libraries (TradingView) - Databases (PostgreSQL, Redis) and ORMs (Prisma, Drizzle) - WASM, service workers, edge functions - Caching strategies (Redis, CDN, in-memory) - Interest in Solana and DeFi ## Beyond Technical Skills We're a small team so a lot comes down to how you work, not just what you know. We want someone who takes ownership of their work and doesn't need to be chased. If you say you'll ship something, you ship it. You're pragmatic about tradeoffs and don't over-engineer. You communicate proactively when things are blocked or slipping. You care about whether what you're building actually moves the needle, not just whether the code is clean. If you need a lot of structure and process to be effective, this probably isn't the right fit. ## Why Bullet - Real ownership and autonomy - Strong team, low bureaucracy - Hard technical problems in a zero-to-one product - Competitive compensation + meaningful equity When applying, mention the word **CANDYSHOP** to show you read the job post completely.
