About Astera
Astera is a private foundation on a mission to steer science and technology toward a better future. We believe the coming years will bring an era of unprecedented scientific and technological advancement as exponential progress in AI converges with central advances in other fields to accelerate innovation. This inflection point provides an unparalleled opportunity to fundamentally rethink the institutions, systems, and tools that drive progress. We have committed a $3.5B endowment to that work and fit the form of our support to the function it serves: grants, investments, and in-house research programs. We accept meaningful risk in the research we back and expect some of it to fail because transformative ideas are rarely the ones already proven. Our projects, and the foundation itself, operate like high-velocity startups, with a high performance bar and competitive compensation to match. We are searching for leaders who are compelled by the challenge of driving high-impact change in the way science is funded, conducted, and communicated.

Position Summary
Astera Institute is seeking a Software Engineering Intern to help build infrastructure for large-scale distributed simulation systems, including biological systems and physics-based environments.
This internship is ideal for someone excited about systems programming, simulation, distributed computing, or scientific infrastructure. You’ll work closely with experienced engineers on real technical problems spanning simulation, networking, orchestration, and performance optimization.
You do not need prior professional experience in all of these areas — we care most about strong technical fundamentals, curiosity, and a willingness to learn quickly.
Areas you may work on include:
Distributed computing systems
High-performance C++ infrastructure
Biological system simulation
3D physics simulation environments
Networking and communication systems
Simulation tooling and visualization
Responsibilities
Contribute to distributed simulation infrastructure and tooling
Help build networking and communication systems for multi-node simulations
Assist with development of MuJoCo-based or other 3D simulation environments
Work on systems for large-scale biological simulations
Improve simulation throughput and system reliability
Debug and profile performance bottlenecks
Build internal tools for orchestration, visualization, and developer workflows
Collaborate with researchers and engineers across simulation and infrastructure projects
Qualifications and Experience
Strong programming fundamentals
Experience with C++, Python, or similar systems languages
Familiarity with Linux development environments
Understanding of data structures, algorithms, and concurrency fundamentals
Interest in distributed systems, simulation, or systems engineering
Ability to learn quickly and work independently on technical problems
Nice to Have
Experience with C++ projects
Familiarity with networking or distributed systems concepts
Experience with physics simulators such as MuJoCo, Unity, or Unreal
Experience with Python, PyTorch, or scientific computing
Familiarity with GPU programming or CUDA
Open-source, research, robotics, or simulation project experience
Interest in biology, neuroscience, or scientific infrastructure
Location
This position is hybrid at our office in Emeryville, CA. Some travel may occasionally be required for collaboration and team events.
Applicants must be currently authorized to work in the United States without the need for employer sponsorship, now or in the future.
Compensation
The posted salary range is based on location in the Bay Area. The successful candidate will receive a competitive compensation package, commensurate with their experience and location.
Cultural Alignment
Surprising problem-solver – you love finding unexpected solutions to problems we don't even know we have, and see options where others only see constraints.
Flexible by default – you don't draw hard lines around your job description and expect your role to evolve significantly over 6–12 months.
Bias to action – you launch and iterate on thoughtful experiments rather than waiting for perfect plans, and you're energized by novel problems.
High standards, internally driven – you believe you can build the world's best vehicle for unleashing extraordinary individuals to create public goods, and you hold yourself to that bar without benchmarking against others.
Open to feedback – You create opportunities to give and receive honest feedback, staying focused on both personal and team growth, and committing to transparency even when it’s uncomfortable.
Operate with the highest levels of integrity, judgment, and stewardship -- you treat residents, peers, and vendors with genuine respect for their time and contributions.
Embrace the tools that define great work today – Astera is building for an AI-driven future and equips the team accordingly. We see these as genuine force multipliers, not optional extras, and we expect our people to use them.
