Kraken is hiring a Network Engineer for Core Infrastructure to design and build data centers and fabrics, implement zero-trust network security, operate and respond to infrastructure requests, and automate tooling and IaC. The role requires 2+ years of network engineering experience, hands-on data-center work, familiarity with firewalls and routing/switching, and exposure to cloud networking and automation tools.

Work on designing and implementing robust, high-performance Rust services and libraries powering trading, payments, and crypto integrations. Collaborate on distributed systems architecture, apply technologies like RPC and Kafka, prioritize security and reliability, and take end-to-end ownership of revenue-critical systems. Requires 3+ years of software engineering experience and proficiency in asynchronous/networked Rust development.

Responsible for scoping, planning, executing, and closing M&A-driven migrations of collaboration platforms and domains into the parent environment. Own platform architecture, governance, email and domain security, eDiscovery and archiving workflows, DLP and access controls, tooling/automation, and vendor management across multiple brands and entities.

Remote Staff Software Engineer for Grafana Labs’ Identity and Access team (role available for candidates in the UK, Germany, Spain, Ireland and Sweden). Lead architecture and implementation of large-scale, low-latency authentication systems (edge redesign), mentor senior engineers, drive organization-wide identity standards, and contribute to reliability and operations. Primary backend development in Go; expertise in modern identity protocols and distributed systems required.

Work on Firefox's security architecture and cryptography stack, design and implement web platform security features, and improve browser reliability, performance, and memory efficiency. Role emphasizes C/C++ proficiency, familiarity with Rust, multi-threaded and cross-platform native development, and applied cryptographic/security knowledge while collaborating across distributed teams.

SearchApi seeks an experienced engineer to own the browser stack: patch browser engines (Chromium/Firefox) in C++, maintain per-OS fingerprint profiles, eliminate automation-detection signals (navigator, WebGL, canvas, audio, fonts, Client Hints, CDP leaks), and build tooling and tests to prevent regressions. The role requires deep reverse-engineering skills, familiarity with large browser build systems, and proven contributions to browser-engine patches or stealth tooling.

Kraken is hiring a Staff (Senior) Security Architect within Kraken Security Labs to design, review, and verify security architecture across a heterogeneous environment. Responsibilities include conducting security assessments and audits, advising blockchain teams, and working hands-on on topics spanning infrastructure security, cryptography, web3, Rust projects, and AI security. Familiarity with OWASP/NIST and strong collaboration and communication skills are expected.

SearchApi seeks a remote Anti-Bot Engineer to research and implement anti-bot evasion, reverse engineer detection systems (Cloudflare, Akamai, DataDome, PerimeterX, etc.), optimize Playwright/Puppeteer/CDP configurations, debug TLS/protocol fingerprinting (JA3/JA4, HTTP/2, HTTP/3/QUIC), analyze network traffic, and run headless browsers reliably at scale. Fluent English and deep hands-on experience with browser internals, fingerprinting, network analysis tools, and relevant tooling (Playwright, Puppeteer, Selenium, Wireshark, Burp Suite, mitmproxy) are required.
