Absinthe Labs | Full-Stack Engineer | REMOTE / NYC Hybrid | Full-Time

About us: Absinthe is building the most sophisticated gamification engine for crypto-native incentive programs. Since 2022, our products have reached 50M+ visits and 2M+ active users. We’re a 10 person, well-funded team shipping fast.

The problem we’re solving: Tracking per-user activity across DeFi protocols sounds simple but is surprisingly hard. Want to know how long someone held an LP position, or which users provided liquidity for more than 30 days? That data is on-chain but can’t be efficiently queried today.

We built an indexing framework that turns protocol events into time-weighted balances and point-in-time actions. Adapters map protocol-specific semantics (Uniswap ≠ Aave ≠ Morpho) into a unified model. The engine handles state, TWAP pricing, and exporting data anywhere. With ~100 lines of adapter code, you can track user balances and contributions at a fidelity no one else supports.

Why it matters: This infrastructure underpins analytics, loyalty, and incentive programs across Web3. We see the Absinthe Adapter Library becoming the default developer layer for embedded finance.

The role: We’re hiring a Full-Stack Engineer to own features end-to-end schema design, wiring GraphQL, polished frontends, and deployment. Our stack: Next.js, Hasura, dbt, MotherDuck/DuckDB, GraphQL, and in-house Web3 indexing. See open positions here: absinthe.network/careers#open-positions

StorPool | Senior Software Engineer - Storage Core (C/Linux) | Remote (UTC-1 to UTC+5) | Full-time | Multiple roles

StorPool is building the future of data storage. Our software runs at the heart of modern clouds, delivering <100µs latency, 113M+ IOPS per cluster, and 99.999% availability. We're profitable, self-funded, and our customers love us (NPS off the charts).

We're looking for a Senior Software Engineer to join our Core Storage team. You'll tackle genuinely hard problems: writing custom Linux drivers, optimizing lock-free data structures at nanosecond scale, building fault-tolerant distributed algorithms, and debugging issues that go all the way down to kernel internals. This isn't CRUD work - it's systems programming at its most challenging.

Competitive salary, fully remote, meaningful time off, and a yearly education budget to keep learning.

If you get excited about shaving microseconds off I/O paths and building infrastructure that simply doesn't break, we should talk.

BuildBetter | Senior Engineer (Backend, Full-stack) | Full-Time | Remote (US) | 170-200k base + equity | Visa Sponsorship not provided

BuildBetter is the product operations platform for customer-led teams. We've built an AI-first product that lets our customers, like Rappi, n8n, and Posthog, automate the operations work that lets them provide their customers with world-class product experiences.

We're looking for two senior engineers to join the team; our headcount has remained small while growing revenue, and we're now bottlenecked by development speed in a way that will make you invaluable. You'll have real ownership over your code from product ideation to customer support, and we'll be making substantive product updates weekly. We're looking for team players who are as fun to work with as they are productive, and are willing to compensate these two rolls commensurately - our aim is to be in the 95th percentile of equity compensation, and we expect that in exchange we'll have value-aligned employees who will help us grow the business.

Joining us will mean solving hard problems at the frontier of AI adoption, including:

- maintaining performance at scale

- building and maintaining rich frontend user experiences that maintain the standards of usability and delight that our customers know us for.

- building agent and workflow systems that automate real work for customers

- playing around with the latest models to figure out new experiences that we can offer our customers as cutting-edge models get released monthly

- building automation that's grounded in supporting product teams rather than automating them - our bet is that this is the likelier outcome out of the current generation of AI systems

Stack: Postgres / TS (Nest + React) / Hasura / EKS / S3 / LLM APIs / Python

Benefits:

- unlimited PTO

- $100/mo education stipend

- flexible hours: we measure productivity in terms of outcomes, not time, so as long as you're able to stay aligned, productive, and in regular communication, we don't really care what hours you work

- health insurance

This may not be the “right” place to ask this, but I am a software engineer in the entertainment industry and it’s pretty bad right now. What is a pivot I can make? My skills are mostly C++ and Python.
