Staff Software Engineer

About the role

The role focuses on building the infrastructure that enables large-scale model training and complex brain simulations. The position also defines the standards that keep research code clean, fast, and production-ready.

Software engineers turn product ideas into working code. Engineers work in small teams, review each other's work, and ship in small batches. Most teams follow agile practices such as sprints and daily standups. Engineers also write tests, fix bugs, and improve performance. The field values clear communication as much as technical skill. Engineers spend part of every week on planning, code review, and debugging, not just writing new code. The ability to explain a technical decision in plain words separates strong engineers from the rest.

Key facts

What you'll do

Infrastructure sets the pace for training large models and running neuroscience simulations, and it is architected for performance and scale. Custom reinforcement learning environments are designed and tuned to reflect neuroscience constraints and to support research workflows. Production-grade code standards are established so that research velocity is accelerated without sacrificing reliability. Research prototypes are transformed into scalable systems that handle real workloads and long-running compute jobs. Systemic technical bottlenecks are tackled across layers, from low-level kernels to high-level strategy, so that research teams can focus on science.

Requirements

The posting states a bachelor's degree requirement. A degree is required as stated in the listed qualifications. Candidates demonstrate high-velocity craftsmanship by balancing rigorous engineering with the need to iterate quickly on research prototypes. Complex systems are architected from scratch, with long-term trade-offs evaluated to ensure infrastructure survives the evolving research environment. Extreme adaptability is shown by moving quickly into neuroscience domains and guiding peers through new concepts. Mastery of hard problems is proven by leading resolution of challenges in massive distributed systems or kernel-level optimization.

Practical notes

Typical interview steps

Hiring for engineering roles usually starts with a recruiter screen, followed by one or two technical rounds. Candidates often solve a coding problem, discuss past projects, and answer system design questions. Some loops include a take-home task. Final rounds typically cover team fit and give candidates a chance to ask questions. Interviewers look for how you break down an unfamiliar problem, not just whether you reach the answer. Practicing a few problems aloud and reviewing your own past projects are the best preparation.

Good to know

Work in this field centers on models that learn from data. Distributed systems and simulation tools form the core of daily work. Rapid experimentation and rigorous testing are common practices. Infrastructure decisions shape the pace of scientific discovery. Cross-disciplinary learning is essential to succeed.

Questions to ask

Good questions to ask the employer in the interview: what does success look like in the first six months, how is the team structured, what is the current biggest challenge, and how are decisions made. Asking about growth paths and the review process is also well received. Employers expect questions, and good ones show preparation.

Career growth

Engineering careers usually progress from individual contributor to senior, staff, and principal levels. Some engineers move into management and lead teams of five to twenty people. Others stay on the technical track. Growth follows demonstrated impact, not tenure alone. A typical engineering ladder has clear levels with defined expectations for scope, quality, and mentorship. Moving up usually requires owning outcomes end to end rather than completing assigned tickets.
