Ready to tackle global challenges that impact business, society, and the environment? Come join us. Why Customs Matters More Than Ever International trade is under more pressure than ever before. With tariffs, shifting regulations, and geopolitical uncertainty, customs has gone from a back-office function to a boardroom priority. The recent trade crisis—sparked by Trump-era tariffs—has made customs the single most complex challenge for global businesses. For many, it’s the difference between keeping supply chains moving or grinding them to a halt. That’s where we come in. The Customs Technology team at Flexport is leading the charge. We are building the systems that help entrepreneurs and global brands navigate complexity, stay compliant, and keep the world’s goods flowing. The opportunity: Customs brokerage is one of the largest, most under-innovated opportunities in logistics. Legacy customs brokers are stuck with outdated systems and manual processes—they simply can’t adapt fast enough. Flexport is growing fast because we’re different. We are the only big tech company in the space, and the only freight forwarder that got founded after the launch of Netscape. Being a tech company, we can move much faster than our competitors, and give our customers the se

About BlockTech BlockTech is a fast-paced algorithmic trading firm. Specializing in crypto options, we facilitate global cryptocurrency derivatives and spot trading, while expanding into new markets. As we continue to grow rapidly, we are looking for a Senior Software Engineer to take technical ownership of the data infrastructure our trading and technology teams are built on. Every decision at BlockTech starts with data: exchange feeds, our own trade and account events, and the history we query to make sense of both. The Foundation team owns the systems that move, aggregate, and store all of it. We run our own Kafka, NATS, PostgreSQL, ClickHouse, and Iceberg, self-hosted and tuned by us. We work primarily in Rust, with Python and SQL alongside. This is a role for an engineer who has already built and operated data infrastructure at scale, and who wants their technical decisions to set direction rather than follow it. What will you do? You will own the pipelines and stores every other team depends on. When a researcher backtests a strategy, when a trader checks a position, when risk queries yesterday, they are all reading data your systems ingested, routed, and kept correct. As a senior engineer, you will also set the technical standards the rest of the team builds against. You will: Own the ingest path. Collect public and private exchange information and internal trading data with minimal latency impact, and land it in our trading systems in real time. Architect the streaming layer. Design and operate our Kafka and NATS messaging systems for the throughput and delivery guarantees our critical flows depend on. Build the storage layer. Develop real-time aggregation and long-term storage across PostgreSQL, ClickHouse, and Iceberg, and make the structural calls that keep queries fast as volumes grow. Run what you build. Own capacity, retention, schema evolution, and failure behavior for infrastructure we host ourselves, with no managed service to hide behind. Make the
