Founding Engineer
Founding engineer — the most senior technical hire — at Omi Health, a pet-health startup running dog longevity tests. You set technical direction and own delivery end-to-end: Python/FastAPI on Postgres/Supabase, a SwiftUI iOS app, React/TanStack web, AWS with Terraform, plus production LLM features, pet-health data modeling, and hostile integrations.
Senior Software Engineer, Data and Orchestration
Senior engineer on Wayve's London Data and Orchestration team, building and revamping data pipeline infrastructure and a new DAG-based orchestration system for the autonomous driving data platform — high-volume ingestion, batch inference, and incident response. Core stack: Python, Kafka, Postgres/ClickHouse; Ray/Flyte/Spark a plus.
Software Engineer, Data Ingestion
Wayve is hiring a data engineer to join its Ingestion Systems team, keeping petabyte-scale Spark/Python pipelines healthy that turn real-world driving footage into data for annotation, model training and evaluation. Day to day this means debugging stalled or failing pipelines, handling corrupt data, and optimising throughput, reliability and cost.
Software Engineer, Data Enrichment
Backend engineer on Wayve's Data Enrichment Platform team, building and operating services, APIs and data-processing workflows that run large-scale ML inference, evaluation and dataset management over petabytes of driving data on GPU fleets. Core stack: Python, distributed systems, workflow orchestrators and Kubernetes.
Senior Software Engineer - Product Expansion Team
Senior backend engineer on the Product Expansion team building core services and event-driven pipelines for Alternative Payments' accounts payable and analytics products. Day-to-day is Go (or similar) and Postgres service development with Kafka/RabbitMQ messaging, testing, and observability for systems processing financial transactions.
Senior Software Engineer
Senior Software Engineer at Goodie AI (NYC, hybrid) building the company's AI platform that gives brands visibility into and optimization of how AI models like ChatGPT and Perplexity represent them. Full-stack work: React front end, Python/Node/Java back end, DevOps/CI-CD, and cloud infrastructure.
Lead Software Engineer - Alti (AI)

Remote role based in Brazil, working in Go, TypeScript/JavaScript, or Python.
Senior Software Engineer - Alti (AI)
Senior Software Engineer on Alternative Payments' Alti team builds and ships AI agent product features end to end — conversational AI, agents, automated routines, RAG pipelines, LLM evaluation, and ML in production — using Go, TypeScript/JavaScript, or Python in a small remote squad based in Brazil.
Data & Integration Engineer
Build and maintain the integrations, data pipelines, and backend services that power VMS's AI agent workforce for healthcare operations — connecting external systems via REST APIs/webhooks, ensuring data quality, and deploying reliable, secure production infrastructure using Python/TypeScript, SQL/PostgreSQL, cloud platforms, and LLM APIs.
Software Engineer - Product
Build and maintain integrations between medical imaging software and customer systems (PACS, RIS, EHR) using DICOM/HL7, while developing internal tools for case management and analytics.
Robotics Software Engineer, SLAM
Develop SLAM algorithms using LiDAR and visual sensors to enable autonomous navigation for service robots in logistics and hospitality settings.
Senior Software Engineer, Fleet Telemetry & Control (Rust)
Builds and maintains distributed energy resource control and telemetry software in Rust/C++ for grid-scale battery fleets and industrial hardware, interfacing with SCADA, PLCs, and low-power embedded systems.
Software Engineer, Distributed Systems
Build cloud-native distributed systems in Go and Python to process trillions of energy-market data points, scaling backend services and APIs for Verse’s energy intelligence platform.
Software Engineer, Product Experience (Energy Storage)
Build full-stack web apps for battery-energy-storage customers using TypeScript, React, Go, and Python; visualize real-time energy data with D3/Echarts.
Finance Systems Software Engineer - AI
Build and maintain AI-powered automation for Halter's finance team, centred on NetSuite and a new EPM tool, using enterprise Claude and native AI features. Day to day you scope, ship, and support production finance tools alongside FP&A and accounting, office-first in Auckland.
Software Engineer
Software engineer at a fast-growing Melbourne AI startup building real-time voice/video AI agents for customer experience. The role spans LLM-powered agents, low-latency real-time systems, backend services and infrastructure using TypeScript, Python, WebRTC, Kubernetes and GCP.
Software Engineer (early team)
Early-stage Sydney energy startup (team of six) that funds, installs and operates batteries for small businesses; each full-time on-site engineer owns a product area end to end — customer app, metering/billing, energy-market data pipelines, or the AI dev platform — using TypeScript, React, Postgres and serverless.
Software Engineer, Inference
Owns the reliability, scale, and efficiency of production inference systems serving live traffic, including Tinker's multi-tenant LLM serving platform. Day to day involves model rollouts, observability, capacity planning, and incident response, working with Python, Go, and distributed systems on GPU/TPU infrastructure.
Founding Engineer
Founding Engineer role at a startup building high-performance data processing platforms. You will design and scale core systems from scratch, focusing on low-latency, high-throughput architectures using a polyglot stack including Python, C++, Java, and TypeScript, while owning the entire lifecycle from architecture to production operations.
Software Engineering Intern
Range is hiring a part-time, in-office Software Engineering Intern at its McLean, VA headquarters to build and ship real full-stack features on its production AI-powered wealth-management platform. Interns work across frontend, backend, and infrastructure with JavaScript/TypeScript (React, Node.js, AWS) alongside engineers, designers, and PMs.
