Location: Austin; Yerevan; London Workplace: OnSite About the role Teza is a systematic trading firm developing quantitative strategies across multiple asset classes. We are looking for a Lead Infrastructure Engineer to own the platform that supports our traders, quants, and developers. This includes colocation hardware near the exchanges, research compute and developer services, and the security and release processes that connect these environments. This is a player-coach role. You will lead the infrastructure team, which includes DevOps Engineers and Infrastructure Engineers, and set its technical direction while remaining hands-on. You will provision and tune bare-metal trading servers, respond to production incidents, and review the designs and solutions your team delivers. We are not looking for a manager who delegates all technical work or an engineer who avoids leading people. We need someone who can do both and determine where their time and attention are most needed. Our platform supports active trading and research today, and we are investing in making it more robust, observable, secure, and developer-friendly. You will have significant ownership and decision-making over infrastructure tooling, standards, and priorities across the firm. Location: Austin, Texas (On-Site) What You'll Own: - Trading Infrastructure and Colocation. Oversee server procurement and lifecycle management across multiple exchange colocations. Select low-latency NICs, such as Solarflare, Exanic, and Mellanox, and kernel-bypass technologies. Develop and maintain Linux tuning standards for trading hosts, including CPU isolation, NUMA-aware pinning, IRQ affinity, and BIOS and kernel settings. Manage hardware failures, spare capacity, and capacity planning. - Research and Developer Platform. Oversee compute orchestration for researchers and data engineers, including Slurm for HPC, machine learning, and GPU workloads; Hadoop for batch processing; and Airflow for workflow scheduling. Support shared services such as JupyterHub, databases, artifact storage, and large-dataset storage. Determine when Kubernetes is appropriate and when alternative approaches are better suited. - Security. Establish and maintain access controls for production trading hosts in colocation. Manage network segmentation across colocation, corporate, and research environments. Oversee secrets management for exchange credentials, API keys, and certificates, including rotation, auditing, and deployment integration. Lead vulnerability management, patching for systems that cannot be routinely rebooted, intrusion detection, and incident response. - Releases and Deployment. Define how trading strategies, data pipelines, and real-time trading systems move from development into production. Establish rollback procedures and release processes for infrastructure changes, including kernels, firmware, and NIC drivers. Oversee infrastructure-as-code pipelines and coordinate releases with the trading calendar. - Operational Maturity. Establish the on-call model and escalation paths. Improve observability across internal services through metrics, logging, tracing, and alerting. Lead incident response and blameless post-mortems, ensuring action items are tracked and completed. - Hybrid Infrastructure. Oversee colocation infrastructure for trading, along with on-premises and cloud environments supporting research and corporate workloads. Evaluate the tradeoffs between these environments, manage cloud costs, and establish disaster recovery plans with defined recovery time objectives (RTOs) and recovery point objectives (RPOs). - The Team. Hire, develop, and retain infrastructure engineers. Set priorities across trading performance and latency, research compute needs, and operational tooling. Represent the infrastructure team and its priorities across the firm. What We're Building Toward: These are the shared goals of the infrastructure team. DevOps Engineers and Infrastructure Engineers execute against them, while you set the technical approach, establish priorities, and drive progress. - Full-stack observability across internal services, including unified metrics, centralized logging, distributed tracing, and actionable alerting. - Reliable, self-service compute orchestration across Slurm, Hadoop, and Airflow, enabling researchers and data engineers to run workloads at scale without unnecessary infrastructure bottlenecks. - Mature secrets management for trading credentials, API keys, certificates, and service-to-service authentication, with rotation, auditing, and deployment integration. - Unified release pipelines that standardize how trading strategies, data pipelines, and real-time trading systems move from development to production. - A well-maintained platform foundation that includes identity management, GitHub Actions runners, VPN, and observability tooling, with updates delivered safely and without disrupting active trading. - A strong security posture across production and research environments, with security practices that evolve alongside the platform rather than being added after the fact. Basic Requirements: - Experience operating infrastructure for a trading firm or another environment with strict uptime and latency requirements, including hands-on experience with colocation hardware and bare-metal Linux servers. - Deep, demonstrable expertise in low-latency Linux, including kernel and network tuning, CPU and NUMA isolation, IRQ affinity, and kernel-bypass NICs and technologies such as Solarflare/Onload, Exanic, and Mellanox/DPDK. You must also have the measurement discipline to validate performance improvements. - Experience leading an infrastructure, DevOps, or SRE team, including hiring, setting priorities, and taking accountability for outcomes while remaining a hands-on technical contributor. - Experience building and operating internal platform services for development and research teams, including CI/CD, compute, storage, monitoring, and developer tooling. Experience consuming these services alone is not sufficient. - Strong Linux systems administration skills and experience with container orchestration technologies such as Docker and Kubernetes. You should understand where containers are appropriate in a trading environment and where they are not. - Familiarity with machine learning and data-intensive workflows, including GPU scheduling, large-dataset access patterns, and reproducible compute environments. - Experience designing and operating hybrid infrastructure across colocation, on-premises, and at least one major cloud provider, such as AWS, GCP, or Azure. You should understand the tradeoffs between these environments. - A practical, mature approach to infrastructure security, including access control models such as zero-trust and bastion hosts, network segmentation, secrets management, vulnerability scanning, patch management, audit logging, and incident response. - Hands-on programming experience in Python or another scripting language, with the ability to build tooling, automation, and infrastructure-as-code solutions rather than simply execute existing playbooks. - A solid understanding of core network protocols and services, including TCP/IP, multicast market data delivery, DNS, LDAP, Kerberos, TLS, HTTP, and SSH. - A track record of managing structured on-call and incident response processes, including escalation paths, post-mortems, and follow-through on action items.   Nice to Have: - Experience with FPGA-based or other hardware-accelerated market data and order-entry systems. - Experience with HPC storage and networking, including NFS at scale, parallel filesystems, and InfiniBand. - Familiarity with infrastructure-as-code tools such as Terraform, Pulumi, and Ansible. - Experience with log aggregation and security information and event management (SIEM) systems. - Understanding of compliance frameworks relevant to financial services.   Benefits -  Health, visual and dental insurance -  Flexible sick time policy

Location: Remote Remote (Americas, US time zones) · Full time About Startale Startale builds onchain finance as a vertically integrated stack: the chains, a JPY stablecoin, payments, and a consumer app. With SBI Group we are building Strium , a fully onchain exchange; we issued JPYSC , Japan's first trust-licensed JPY stablecoin; with Sony Group we operate Soneium ; and Startale App , used by 210k monthly users, is the front door to all of it. We raised a ~$63M Series A from Sony, SBI and others. The team is ~70 people across 20 nationalities, and English is the working language of engineering. Why US time zones Our engineering team is spread across Asia and Europe. This role anchors infrastructure coverage in US hours: you will be the infrastructure owner awake when most of the team is not. You must be physically based in a US time zone (UTC-8 to UTC-5), whether in the US, Canada, or Latin America. Working US hours from another region does not qualify. About the Role We are looking for a Senior DevOps / Infrastructure Engineer to own the infrastructure, deployment, and operational systems behind StartaleApp, Strium, and other products across the Startale ecosystem. This is a senior, hands-on role: you design, build, and operate production infrastructure end to end, from cloud and Kubernetes to CI/CD, databases, observability, and security. You will work primarily on two demanding products. StartaleApp is a user-facing Web3 wallet and application platform whose backend combines traditional cloud services and databases with blockchain nodes, indexers, and transaction processing. Strium , built with SBI Group, is a next-generation decentralized exchange bringing Japanese equities onchain, with a fully onchain order book and a consensus layer purpose-built for low-latency, high-throughput trading. Both run under high load, strict availability and security requirements, and real production conditions. We want someone who builds infrastructure rather than maintains it: comfortable making architectural decisions, automating everything that repeats, and diagnosing complex production issues. Experience running blockchain infrastructure is a significant advantage, and a SecOps or cloud security background is a major plus. What You Will Do Own infrastructure architecture and operations for StartaleApp, Strium, and other production systems. Design, build, and operate highly available cloud infrastructure on AWS: Kubernetes clusters, networking, storage, scaling, upgrades. Manage everything as code: Terraform, GitOps, and CI/CD pipelines with safe rollouts and rollback. Operate PostgreSQL in production: availability, replication, backups, performance, recovery. Build observability across infrastructure, applications, databases, and blockchain nodes, with alerting that catches incidents early. Run blockchain infrastructure (nodes, RPC services, indexers) and monitor it down to protocol level: sync, connectivity, transaction processing. Design disaster recovery and failover for critical systems, and harden security: access control, secrets, vulnerability management, monitoring. Diagnose production incidents across the full stack, and remove operational bottlenecks with automation instead of manual procedure. What You Bring 5+ years in DevOps, SRE, platform, or infrastructure engineering. A track record of building and operating production infrastructure for highly available systems, where availability directly affected users or the business. Deep hands-on Kubernetes, AWS, and Linux experience. Infrastructure as code with Terraform, GitOps practices, and CI/CD pipeline design. Solid networking fundamentals: DNS, load balancing, TLS, service discovery. PostgreSQL in production: replication, backups, recovery, performance. High-availability design, incident response, root-cause analysis, and capacity planning. Hands-on experience operating blockchain infrastructure (nodes, RPC, indexers, validators, or data pipelines) and an understanding of how distributed blockchain networks fail. Strong Plus Security: SecOps or cloud security experience, hardening production environments, AWS security services and IAM design. Platform breadth: bare-metal operations, Helm or ArgoCD, messaging systems such as Kafka or NATS, observability stacks such as Prometheus, Grafana, Loki, or OpenTelemetry. Blockchain depth: operating chain infrastructure at significant scale; Ethereum, Polkadot, or L2 ecosystems. Domain: financial, trading, or other latency-sensitive systems; using AI tools in infrastructure workflows; Go, Rust, or TypeScript. How We Think About This Role We care less about specific tools and more about how you engineer: Build infrastructure, not just operate it, and own problems from architecture through production. Design for high load and partial failure, and automate what repeats. Diagnose across the full stack, from Kubernetes and networking to databases and blockchain nodes. Treat infrastructure as a product, with users, reliability requirements, and long-term maintenance needs. Why Join Build and operate the core infrastructure behind StartaleApp and Strium, including a DEX designed for high-throughput, low-latency trading. One role spanning cloud, Kubernetes, distributed systems, databases, and blockchain infrastructure. Significant ownership and direct product impact in a small, highly technical team. Competitive compensation and equity.
