Software Engineer, Feature Team

We are looking for a versatile generalist who thrives on a high degree of personal responsibility. You want to be involved in the whole process, all the way from requirements through implementation and deployment, and you enjoy working across the entire application instead of being stuck in a silo. What You’ll Be Doing As a member of our feature team, you’ll dive into our UI, JS and back end to make investment portfolio management scalable and easy to use. This is a complex domain that needs to be distilled into a clear experience that allows financial advisors to understand the impact of their choices and present the best possible information to their clients. You’ll work closely with our product management team and our users to gather requirements and design solutions that make this happen. To solve the technical challenges, you’ll need to quickly wrap your head around complex user workflows. You’ll need a solid understanding of computing principles, strong analytical skills and good technical intuition. You’ll also need good communication skills to explain issues, potential solutions and tradeoffs in ways that make sense to a variety of stakeholders. Whenever you need to build internal tools or pick up new skills to achieve our goals, you’re able to roll up your sleeves and bootstrap quickly. About Us Smartleaf is a Boston-based investment portfolio rebalancing service handling over $90 billion in assets. Our next milestone is doubling our capacity to handle 1 million accounts. In order to get to this next level of scale, we need to evolve our architecture and you can have a big impact on how we do that. We need a teammate who will ramp up quickly and help us get things done. We have more things to do than people to do them; if you are proactive, competent and reliable you can earn responsibility very quickly and help shape the way the department functions. We value software engineering as a discipline. We’ll use AI where it reduces toil but not where it reduces understanding. We still expect every teammate to own and be able to explain every line of code they ship. Generating lines of code has never been our bottleneck; figuring out the right problem to solve and the right thing to build is far more important. If you can bring skill, attention to detail and focus on getting working code into the world, while being a genuinely nice person to work with, we want to talk to you.
