What You’ll Do As a Senior Software Engineer, you’ll work at the intersection of software engineering and machine learning operations. This role is intentionally broad. We’re hiring multiple engineers with complementary strengths across platform engineering and ML systems. No single person is expected to cover everything. Depth in one area, strong fundamentals, and the ability to collaborate effectively matter more than perfect overlap. Part of the work focuses on core platform engineering: designing and building services, evolving system architecture, improving reliability, resolving issues, and making sound trade-offs in areas such as database design and schema evolution. Another part focuses on ML systems: ensuring models run reliably, efficiently, and at scale, turning research into production-ready tools. This includes deploying, monitoring, and optimizing AI workloads using Python and solid software engineering practices. Qualifications Must-Have Qualifications Bachelor’s or Master’s degree in Computer Science, Engineering, or related field (or equivalent experience). Solid programming skills in Python (plus experience with frameworks such as FastAPI, Flask, or Django). Hands-on experience with ML model deployment and monitoring in production. Knowledge of containerization (Docker). Experience building CI/CD pipelines (GitHub Actions). Experience working within startups / scaleups. Strong communication skills and a collaborative mindset. Knowledge of Agile delivery models (Scrum/Kanban) and software development best practices. 3+ years of hands-on experience building production-grade systems. Preferred Skills Understanding of optimizing both CPU-bound and GPU-bound workloads. Knowledge of monitoring and observability tools (e.g. Prometheus, Grafana, ELK stack). Experience with Infrastructure as Code (Terraform). Experience with Azure. Identifying and resolving bottlenecks in distributed machine learning workloads (knowledge of low-level languages and CUDA library is a plus). Experience in building design automation products within the construction industry. Additional Information Our Hiring Process 25-minute screening call. Coding challenge: A hands-on task to assess your problem-solving and technical skills. Final cultural fit: In-person meeting with our leadership team. Why Join Us? Work on real-world problems where AI creates measurable impact. Be part of a team where your work matters, and your ideas become real. Collaborate with sharp, driven colleagues in a culture of trust, ownership, and high standards. Contribute to making the built environment smarter and more sustainable. #LI-CC1 About AECOM AECOM is the world’s trusted infrastructure consulting firm, delivering professional services throughout the project lifecycle – from advisory, planning, design and engineering to program and construction management.
